In scenarios where the reliability of locks is highly critical, such as in industrial equipment, communication cabinets, and rail transit, the quality of a passive cam lock that can operate stably in dusty, vibrating, and high/low temperature environments not only affects equipment safety but also directly impacts production efficiency. As a manufacturer specializing in industrial locks, we are well aware that the "passive advantage" (battery-free, maintenance-free) of passive cam locks is backed by a comprehensive quality control system from raw materials to finished products - every qualified lock must undergo 12 rigorous inspections before it can be finally shipped out. Raw material end: Quality genes starting from "material selection" The durability of industrial passive cam locks primarily depends on the "inherent quality" of the raw materials. We establish three thresholds in the raw material procurement process: The core material is locked to 316 stainless steel: Compared to the commonly used 201 or 304 stainless steel in ordinary industrial locks, 316 stainless steel contains molybdenum, which enhances its corrosion resistance by more than 3 times, making it particularly suitable for wet and salt-spray environments such as chemical and marine environments. Each batch of steel requires a material certificate and is tested using a spectrometer to ensure that the chromium, nickel, and molybdenum content meets the standards (chromium ≥16%, nickel ≥10%, molybdenum ≥2%). ​ The lock cylinder assembly is made of engineering plastic PA66 + glass fiber: the internal transmission parts of the cam lock need to be both wear-resistant and tough. The PA66 material with 30% glass fiber can withstand temperature fluctuations from -40°C to 120°C, and its friction coefficient is lower than 0.15 (about 0.3 for ordinary plastic), ensuring long-term rotation without jamming. The raw materials need to undergo temperature resistance testing before being stored: they are placed in a 120°C oven for 72 hours, and are considered qualified if they are not cracked or deformed after cooling. ​ Electronic module screening for "military-grade" chips: The NFC sensing module of the passive cam lock is the core component. We choose chips that support the ISO 14443A standard, which can maintain stable communication in an environment ranging from -40°C to 85°C, and have an anti-electromagnetic interference capability of Level 3 (able to withstand common electromagnetic radiation found in industrial equipment). Each chip undergoes 2000 cycles of high and low temperature testing (alternating between -40°C and 85°C), and products with signal attenuation exceeding 5% are eliminated. Production process: "Zero tolerance" control of 3 key processes 1. The structure of the passive cam lock is precise (with part tolerances controlled within ±0.02mm), and any deviation in any step may lead to functional failure. We focus on controlling three key processes during production: 2. Precision machining to "micron-level" standards: The lock housing is processed using a CNC machine tool, employing five-axis linkage technology to ensure that the coaxiality error between the lock hole and the cam is ≤0.01mm - this precision is equivalent to 1/5 of the diameter of a human hair. After processing, each piece is inspected using a three-coordinate measuring machine, recorded, and archived. Non-conforming products are directly scrapped. ​ 3. The "dust-free" requirement for the assembly process: In a Class 1000 clean room, workers must wear anti-static wrist straps while assembling internal components to prevent dust from entering the lock body and affecting the transmission. Key steps, such as spring installation and chip soldering, are equipped with high-definition microscopes to ensure that the error in the reset force of the spring is controlled within 0.5N (feeling uniform and without any jamming). ​ 4. Verification of "Sealing Performance" for Ultrasonic Lamination: The housing and base of the passive lock utilize ultrasonic lamination technology (instead of traditional screw fixation). The joints must be tested using a helium mass spectrometer leak detector, with a leakage rate of ≤1×10⁻⁹ Pa・m³/s, ensuring IP67 waterproofing (able to withstand immersion in 1 meter of water for 30 minutes without leakage). Finished product testing: 12 rigorous tests simulating "extreme operating conditions" A qualified industrial passive cam lock must withstand the "harsh test" on site. Our finished product inspection process covers 12 rigorous tests, and only products that pass all tests can be labeled and shipped out: Mechanical life test: Simulate unlocking/locking actions with automated equipment, operating continuously for 50,000 times (equivalent to a usage frequency of 5 years in industrial scenarios). After the test, the lock cylinder must still operate smoothly, without any jamming or loosening. ​ Vibration resistance test: Fix the lock on a vibration table and subject it to frequency-sweep vibration within the frequency range of 10Hz~2000Hz for 4 hours (simulating vibration during truck transportation and equipment operation). Afterwards, check that the internal components are not loose and the function is normal. ​ High and low temperature cycling test: Place the device in an environment at -40℃ for 2 hours → place it at room temperature for 30 minutes → place it in an environment at 85℃ for 2 hours → place it at room temperature for 30 minutes. Repeat this cycle 10 times. After the test, the attenuation of NFC sensing distance should not exceed 10% (standard sensing distance ≥3cm). ​ Salt spray test: Place the item in a salt spray chamber with a 5% concentration for 48 consecutive hours. After removal, rinse with clean water. The rusted area on the lock surface must not exceed 5%, and there must be no functional damage (most industry standards are for 24 hours). ​ Tamper resistance test: Apply a torque of 10N·m to the lock cylinder using a specialized tool (equivalent to an adult exerting full force to twist it), and the lock body must not deform, and the cam must not dislodge from its original position. ​ In addition, it also includes humidity testing (placed in a 95% RH environment for 72 hours), drop testing (free fall from a height of 1 meter onto a concrete floor), NFC anti-interference testing (able to sense normally even when there are devices such as mobile phones and walkie-talkies within a 1-meter range), etc., to comprehensively verify the reliability of the lock. Customized quality control: tailoring measures to the specific scenario The needs of different industrial scenarios vary greatly: chemical workshops require stronger corrosion resistance, while rail transit equipment demands higher vibration protection. As a manufacturer, we offer "customized quality control solutions" For offshore platform scenarios, the salt spray test standard can be raised to 96 hours; ​ For military equipment, add impact resistance testing (capable of withstanding an impact with an acceleration of 500G); ​ For food processing workshops, food-grade lubricants are used, which have passed FDA certification testing. ​ Each batch of customized products is accompanied by a "quality archive" that records the batch of raw materials, processing parameters, and testing data, enabling customers to trace and query. Additionally, we offer complimentary sample testing services, allowing customers to take samples back to their sites for trial use to verify their compatibility with their specific working conditions. Why is "quality control" more important than "function" in industrial locks? The cost of lock failure in industrial scenarios often far exceeds the cost of the lock itself: a broken lock in a communication cabinet may lead to the shutdown of a base station; a malfunctioning lock in chemical equipment may trigger safety accidents. The "maintenance-free" advantage of passive cam locks is predicated on "high reliability" - if frequent replacement is required due to quality issues, it will actually increase costs. ​ Our quality control system essentially employs "extreme testing" to simulate "daily use" and utilizes "full-process traceability" to replace "post-event remediation". For industrial customers who pursue long-term stability, choosing a passive cam lock that has undergone rigorous testing is not just about selecting a product, but also about choosing "peace of mind". ​ If your equipment has special working condition requirements for locks, or if you want to learn more about quality control details, please feel free to send us a private message. We can provide customized testing solutions and free samples, ensuring that every lock becomes a "reliable barrier" for equipment safety.

Every aspect of logistics and distribution cannot be separated from "locks" - containers need locks, truck bodies need locks, and end-of-line distribution cabinets also need locks. However, the pain points of traditional padlocks have long become a persistent issue in the industry: lost keys leading to unopenable containers, violent lock-picking causing theft of goods, and time-consuming and laborious manual registration of unlocking records... The emergence of battery-free NFC smart disc padlocks is redefining the value of logistics locks with "passive intelligence", improving the security efficiency of the entire chain from warehousing to the end by 300%. Battery-free design: a "durable" and rigid demand in logistics scenarios The "living environment" of logistics locks is harsh: containers are subjected to salt spray erosion during rough seas, truck interiors can reach temperatures of 60°C under intense sunlight, and last-mile delivery vehicles may navigate through heavy rainstorms. In such an environment, the battery life of traditional electronic locks either plummets (from three months to one month) or the battery swells and fails outright. However, the "passive black technology" of the battery-free NFC smart disc lock has elegantly solved this problem. ​ Its core principle lies in NFC reverse power supply technology: when the delivery person holds their phone close to the lock, the NFC signal from the phone instantly powers the lock, completing the identity verification and unlocking process. The entire process eliminates the need for an internal battery, thus eliminating the embarrassment of "being unable to unlock due to battery depletion" - even in cold chain compartments at -40℃ or high-temperature cargo containers at 85℃, the lock remains stable and functional. ​ Crucially, the battery-free design ensures the lock body achieves IP68 full sealing. The housing is made of zinc alloy die-casting and stainless steel latch, which not only withstands high-pressure water gun washing but also endures severe vibrations during truck transportation, effectively addressing the issues of "rust and jamming" and "collision damage" inherent in traditional padlocks. Test data from a cold chain logistics enterprise shows that after using this lock, the rate of delivery delays caused by lock malfunctions has decreased by 92%. Mobile phone as key: Reconstructing logistics permission management logic The "key management" in the logistics industry has always been a perennial problem: a truck may need to be handed over multiple times by drivers, warehouse staff, consignees, etc., posing a high risk of key loss or duplication; when there is a need for temporary goods adjustment, special personnel have to be assigned to deliver the keys, resulting in a significant waste of manpower. ​ The battery-free NFC smart disc padlock, through the "mobile phone authorization" mechanism, makes permission management flexible and controllable: ·Remote issuance of temporary permissions: The dispatch center enters the consignee's phone number in the backend, allowing the recipient to unlock with their phone's NFC. Permissions can be set with a time limit (e.g., "valid for 2 hours") or a limit on the number of unlock attempts (e.g., "limited to 1 unlock"). They will automatically expire after the set time limit. After using this feature on a certain city distribution platform, the communication cost for temporary goods adjustments has been reduced by 70%, eliminating the need for specially-assigned personnel to deliver keys. ​ Multi-level permission hierarchy: Different permissions are set for different roles in the logistics chain (driver, warehouse administrator, customer) - drivers can only unlock the trucks they are responsible for, administrators can view the status of all locks, and customers can only open the corresponding delivery cabinets, avoiding security risks caused by confusion of permissions. ​ Offline unlocking without delay: Even in remote areas without network coverage, the lock can store up to 1000 authorized records, which will be automatically synchronized to the backend once connected to the internet, ensuring normal use in scenarios such as mountainous area deliveries and cross-border transportation. Fully traceable: from "disappearing goods with no clear explanation" to "every step is recorded" The "difficulty in defining responsibility" after goods are lost is a common trigger for logistics disputes: the driver says "the lock was fine", the warehouse says "there was no problem during delivery", and in the end, nothing can be done. The "electronic ledger" function of the battery-free NFC smart disc lock makes every unlocking traceable. ​ After each unlocking, the lock automatically records information such as the unlocker, time, and location (combined with mobile phone positioning), and uploads it to the management platform in real time. Administrators can query by "lock number", "time period", "operator", and other dimensions in the background to generate visual reports. More importantly, the records are stored in encrypted form and cannot be tampered with, which can directly serve as the basis for determining responsibility in case of disputes over lost goods. ​ A cross-border logistics company once quickly identified the suspect in a container theft case through unlocking records. The system showed that there were three abnormal unlockings during non-scheduled times, and the locations matched the suspicious vehicle tracks captured by surveillance cameras, providing crucial evidence for solving the case. Compatible with all logistics scenarios: from containers to end-of-line distribution cabinets The "versatility" of the battery-free NFC smart disc padlock enables it to cover different scenarios across the entire logistics chain: Mainline transportation: For large equipment such as containers and semi-trailers, the locks can withstand a tensile force of 1.5 tons, are tamper-proof and shear-resistant, and are equipped with an electronic fence function (automatically alarms when leaving a designated area), reducing the risk of theft during long-distance transportation. ​ Urban distribution/express delivery: For small scenarios such as electric vehicle trunks and delivery cabinets, the lockset has a diameter of only 5cm and weighs 50g. No drilling is required for installation, and replacement can be completed in 3 minutes, making it particularly suitable for rapid renovation of express delivery outlets. ​ Warehousing process: Used for locking temporary containers and turnover boxes. Administrators can view the on/off status of all locks in bulk through their mobile phones, eliminating the need for individual inspections and increasing inventory efficiency by 3 times. ​ The practice in a certain e-commerce logistics park shows that after installing the lock on 100 turnover boxes, the inventory time was shortened from 8 hours per day to 2 hours, and the error rate was reduced from 3% to 0.1%. Why is it called an "invisible driver" for logistics cost reduction and efficiency improvement? The costs in the logistics industry are hidden in every detail: a delay caused by a lock malfunction may spoil an entire vehicle's fresh produce; a lost key may require hundreds of yuan to pry open and replace the lock; a dispute over lost goods may result in tens of thousands or even hundreds of thousands of yuan in losses. ​ The value of the battery-free NFC smart disc padlock lies not only in being a "more durable lock", but also in helping logistics enterprises plug these invisible loopholes through three major features: "passive maintenance-free", "digital authorization", and "traceable records". A third-party logistics enterprise has calculated that after using this lock, the annual average maintenance cost of locks has decreased by 68%, the processing time for cargo damage disputes has been shortened by 80%, and the overall operational efficiency has increased by 23%. ​ If your logistics team is still struggling with issues such as "inability to lock, poor management, and unclear communication", why not give this smart lock a try, which redefines "logistics security"? Apply now for free samples and receive customized solutions tailored to different scenarios (such as a low-temperature-resistant version specifically for cold chain use and a high-security, industrial-grade version), ensuring every delivery is more secure and efficient.

Padlocks, as one of the oldest and most common locks, have always played a fundamental role in the field of security. However, traditional padlocks rely on mechanical keys, there are easy to lose, difficult to manage, weak security and other issues. With the integration of passive electronic technology, padlocks ushered in an intelligent breakthrough, passive electronic padlocks by virtue of the “battery-free, traceable, high-security” features in a number of scenarios to show the unique value of redefining the boundaries of the application of padlocks. Logistics Transportation: Keeping Cargo Safety Under Control In long-distance freight transportation and container transportation, the key management of traditional padlocks is a difficult problem -- the driver, warehouseman and consignee hand over the keys to each other, which is not only inefficient, but also has the risk of the keys being copied. Passive electronic padlock perfectly solves this pain point: it does not need a key, through the NFC card or cell phone APP authorization to open the lock, each time the lock will automatically record the time, the operator and other information, synchronized to the management platform. Managers can view the lock status of goods in transit in real time through the backstage, and if there is abnormal locking, the system will immediately warn you, thus reducing the possibility of goods being stolen or switched from the root. In addition, its anti-pry structure and IP67 waterproof performance can withstand bumps, rain and dust during transportation, ensuring safety throughout the process. Power communication: to protect the stable operation of outdoor equipment Power base stations, communication cabinets and other outdoor equipment is widely distributed, the traditional padlock is exposed to the wind and sun for a long time, easy to rust and jam, and the key is easy to be accessed by unauthorized personnel, threatening the safety of the equipment. Passive electronic padlock is made of stainless steel and sealed design, can work stably in extreme environment from - 40℃ to 85℃, completely get rid of the trouble of “rusty deadbolt”. Operation and maintenance personnel do not need to carry a large number of keys, only with an authorization card can open all padlocks within the jurisdiction, significantly improving the inspection efficiency. What's more, through the hierarchical management of authority, the scope of locking can be restricted to different personnel -- for example, maintenance personnel can only open the cabinets in the responsible area, and the administrator can view the locking records of all the equipment, so as to make the management of outdoor equipment more standardized. Sharing Economy: Activating the Safe Circulation of Idle Resources In the fields of shared bicycles, shared charging treasures and shared tools, the “one-size-fits-all” management of traditional padlocks can hardly meet the demand for refined operation. Passive electronic padlock supports temporary authorization function, users can get short-time unlocking authority through APP code scanning, and it will be locked automatically after use, without manual intervention in the whole process. For the shared tool cabinet, it can realize the traceability management of “who receives, who returns” through the authority setting, which reduces the loss rate of tools. Its “battery-free” characteristics do not need to worry about longevity, even if the equipment is idle for a long time, it can always respond to the unlocking command, reducing the operator's maintenance costs. Warehouse Management: Enhancing the Security Level of the Warehouse Area The confusing key management of large warehouses and cargo containers is a common pain point, and once the key is lost, it may lead to the failure of the security system of the whole warehouse area. Passive electronic padlock can be linked with the warehouse management system, for different positions, different goods set exclusive locking privileges: forklift drivers can only open the padlock of the designated cargo area, temporary workers do not have access to high-value goods area. The unlocking record is synchronized to the system in real time, which is convenient for checking the correlation between goods in and out of the warehouse and locking operation at the end of the month inventory, making the warehouse management more accurate. At the same time, its anti-shearing and anti-sawing physical structure can effectively resist violent damage, adding “double insurance” for cargo safety. Campus and Park: Simplifying Public Facility Management In the sports equipment rooms and laboratories in schools, and public lockers and green belt fences in parks, traditional padlocks are often forced to be picked and replaced due to key loss, which is a waste of cost and affects usage. Passive electronic padlock support batch authorization and permission recovery, the new semester for teachers and students to open locker permissions, graduation one-key recovery; laboratory hazardous materials storage cabinets can be set up “two-person authorization” mode, requiring two administrators at the same time to verify that the locks, to eliminate security risks. Its operation is simple and intuitive, no need for complex training to get started, especially suitable for public scenes with frequent personnel movement. From freight cars to outdoor cabinets, from shared equipment to campus facilities, passive electronic padlocks with “keyless management”, “full-process traceability”, “extreme environmental adaptation” three core advantages It breaks the application limitations of traditional padlocks. It is not only a lock, but also a set of lightweight security management solutions, so that the originally dispersed security nodes to form a linkage network, in order to enhance the security at the same time, significantly reduce the management costs, and become the “finishing touch” of the intelligent upgrading of various industries.

In scenarios such as heavy industrial workshops, outdoor base stations, and chemical warehouses, the locks on equipment cabinet doors often face a "triple test": continuous erosion from high-temperature oil and grease, pervasive dust and moisture, and mechanical wear from frequent opening and closing. Traditional mechanical locks are prone to rust and jamming, while electronic locks frequently "strike" due to battery failure. However, a rotary handle lock equipped with "passive electronic technology" is redefining the durability standards for industrial locks. Passive design: From "battery-changing anxiety" to "once and for all" The "battery replacement dilemma" in industrial scenarios is far more intractable than imagined: The battery life of locks in high-temperature workshops can be drastically reduced from one year to three months, and the labor cost for downtime to replace the batteries far exceeds the cost of the locks themselves; ​ The cabinet door of the outdoor wind turbine tower is tens of meters above the ground, requiring the erection of scaffolding for each battery replacement, with a single cost reaching several thousand yuan; ​ For explosion-proof locks in chemical warehouses, dismantling the casing to replace the battery may violate safety regulations and even pose compliance risks. The "passive electronic solution" for rotary handle locks directly addresses the pain point: it eliminates the need for an internal battery and relies on NFC energy induction technology for power supply. When an authorized mobile phone or card reader is brought close to the lock, the NFC signal instantly powers up the lock, completing the identity verification and unlocking process. The entire process is contactless and power-free, effectively eliminating the risk of "battery failure" from the root. ​ Crucially, the passive design enables the lock body to achieve a fully sealed structure. The casing of this rotary handle lock is forged from 316 stainless steel, achieving a waterproof rating of IP69K (able to withstand direct high-pressure water jets), and a temperature range of -40°C to 85°C. Even if it is immersed in oil, acid, or alkali mist for extended periods, the internal electronic components can maintain stable operation. Electronic encryption + mechanical anti-tampering: dual protection against industrial-grade brute force The security requirements in industrial settings have never been about "guarding against the honest but not the dishonest" - once the wires, instruments, and materials inside equipment cabinets are maliciously tampered with, it could lead to production downtime or even safety accidents. ​ The core competitiveness of this rotating handle lock lies in its dual protection of "electronic encryption" and "mechanical anti-pry": More precise permission management: Through the supporting management system, multi-level permissions (such as administrator, maintenance worker, temporary visitor) can be set. Each lock corresponds to a unique ID, and remote revocation of permissions is supported, avoiding the risk of "losing control when the key is lost" associated with traditional mechanical locks; ​ Operational records are traceable: Every unlocking generates an encrypted record (including time, operator, and device number), which is synchronized to the cloud platform. Even if the network is disconnected, the data can be stored locally, and it will be automatically uploaded once the network is restored later, meeting the compliance requirements of industrial auditing; ​ Mechanical structure resistance to violence: The rotating handle adopts an "idle anti-pry design", ensuring that when subjected to violent twisting, the lock cylinder will separate from the handle, preventing damage to core components. The lock bolt is made of hardened alloy material, with a shear resistance strength of 15kN, far exceeding the 8kN standard of ordinary industrial locks. "Detail evolution" tailored for industrial scenarios In practical applications, the "ease of use" of industrial locks is often overlooked. However, the numerous detailed designs of this rotary handle lock precisely address the pain points of frontline operations: It can be operated with gloves: the handle diameter is thickened to 32mm, and the surface is treated with anti-slip knurling, so that workers can easily rotate it even when wearing heavy labor protection gloves; ​ Blind operation with precise alignment: The installation tolerance between the lock body and the cabinet door can accommodate ±2mm, ensuring smooth locking even if the cabinet door experiences slight displacement due to long-term vibration of the equipment; ​ Quick replacement of old locks: The dimensions are compatible with 80% of the industrial cabinet door pre-drilled holes on the market, eliminating the need for re-drilling. Replacing old locks takes only 10 minutes, without affecting production progress. ​ Currently, this lock has been implemented in various scenarios such as automobile welding workshops, offshore oil platforms, and waste-to-energy power plants. A certain automobile factory reported that after replacing traditional locks, the "unlocking time" for equipment maintenance was shortened from an average of 5 minutes to 10 seconds, resulting in a reduction of 23 hours of downtime caused by lock malfunctions throughout the year. A new energy power station has improved the efficiency of tracing unlocking records of outsourced construction teams by 300% through its permission management function. The "durability revolution" of industrial locks begins with passive solutions As Industry 4.0 moves towards "unmanned and intelligent" operations, locks, as the "last line of defense" for equipment security, have evolved beyond being mere "switching tools" and have become important nodes in the industrial Internet of Things. ​ The passive electronic solution of this rotary handle lock is essentially designed with "low maintenance and high reliability" to meet the stringent requirements of industrial scenarios. It proves that good industrial products are not created by pursuing extreme parameters in the laboratory, but by maintaining stable performance in real environments with oil, dust, and high temperatures. ​ If your workshop is still struggling with rusty locks, battery failures, and confusing permissions, consider this "maintenance-free" rotary handle lock. Contact us now to obtain customized solutions tailored to different industrial scenarios, transforming equipment security from "constant firefighting" to "once and for all.".​

While traditional padlocks still rely on keys and batteries, a game-changing "battery-free NFC smart disc padlock" has quietly gained popularity. It eliminates the need for frequent battery replacements, allows unlocking with just a tap on your phone, and enables remote authorization of temporary permissions and real-time tracking of every unlocking record. For scenarios such as logistics warehousing, container transportation, and self-service lockers, this may be the optimal solution to address issues like chaotic key management, difficult permission control, and lack of security traceability. Why is "battery-free" a hard power? The pain points of traditional electronic locks often start with "changing batteries": The locks on logistics trucks are exposed to the wind and rain all year round, causing the battery life to dwindle quickly. In winter, when temperatures are low, they may even malfunction, making it impossible to unlock the truck at crucial moments; ​ The locks of self-storage facilities are scattered across hundreds of cabinets, and checking the battery level of each one is a "physical labor". Missing even one could lead to customer complaints; ​ Replacing the battery of the lockset for outdoor equipment requires climbing high and dismantling the equipment, which is not only troublesome but may also affect the sealing performance of the lockset due to improper operation. ​ The core breakthrough of the battery-free NFC smart disc padlock lies in the adoption of "energy harvesting technology" - when a mobile phone approaches the lock, the NFC signal instantly powers the lock, completing the transmission and execution of the unlocking command. The entire process eliminates the need for a built-in battery, saving the cost of frequent battery replacement and avoiding potential safety hazards caused by battery failure. ​ More importantly, the absence of a battery means that the lock can be completely sealed. The casing of this disc padlock is made of high-strength zinc alloy through die-casting, achieving a waterproof rating of IP67. It can function normally even when submerged in water or exposed to prolonged rain, making it particularly suitable for outdoor, humid, and other harsh environments. Remote authorization: Say goodbye to the cumbersome "key handover" For scenarios that require frequent temporary authorization, such as: The logistics company permits drivers to temporarily open containers for unloading; ​ The warehouse administrator grants customers a 2-hour self-service pickup access; ​ Equipment maintenance personnel need to enter the computer room for maintenance at one time Traditional solutions either rely on "manually delivering keys" or involve leaving spare keys, posing security risks. However, the battery-free NFC smart disc padlock, through its accompanying management app, enables "precise remote access control":​ The administrator selects the corresponding lock on the APP, sets the authorization object (phone number/WeChat), unlocking time (such as "9:00-12:00 on October 1, 2023"), and unlocking times (such as "limited to 1 time"); ​ Upon receiving a text message or an APP notification, the authorized person can unlock the lock by simply tapping the phone's NFC function against the lock (supporting both Android and iOS systems), without the need to download any software; ​ The permission will automatically expire upon expiration, eliminating the need to reclaim the key and the concern of permission abuse. ​ This "use-and-grant" model not only saves labor costs, but also enables fine-grained management through permission segmentation (such as "read-only permission" and "full permission"), making it particularly suitable for enterprise users who collaborate across multiple scenarios. Unlocking record inquiry: every operation has an "electronic ledger" The core of security management lies in "traceability". However, traditional padlock unlocking records rely entirely on manual registration, which often leads to omissions, errors, and falsifications. ​ Every unlocking operation of the battery-free NFC smart disc padlock will be synchronized in real-time to the cloud management platform: The record includes: unlocker, unlock time, unlock location (requiring cooperation with APP positioning), unlock method (authorized unlock / administrator unlock); ​ Administrators can filter and query by time, lock number, operator, and other dimensions in the backend, and generate Excel reports; ​ In the event of abnormal unlocking (such as brute force cracking), the system will automatically send an alarm message to the administrator's mobile phone, achieving "early warning for abnormalities". ​ For industries requiring compliance audits (such as cold chain logistics and hazardous goods transportation), these records can also serve as electronic vouchers for "operational compliance", avoiding liability disputes caused by incomplete manual records. Who needs such a smart padlock? From the perspective of practical application scenarios, this battery-free NFC smart disc padlock is particularly suitable for three types of users: Logistics and transportation industry: temporary unlocking management of containers, trucks, and freight containers, reducing key handover costs; ​ Self-service storage and shared space: Users can unlock mini-storage units, lockers, and shared tools independently, enhancing service efficiency; ​ Outdoor equipment and engineering: Anti-tampering and remote authorization for communication base stations, power cabinets, and municipal facilities, reducing maintenance costs. ​ Currently, multiple logistics enterprises have reported that after using this padlock, the duration of a single temporary authorization has been shortened from "2 hours" to "5 minutes," resulting in a 70% reduction in key management costs. A certain self-storage brand has successfully resolved multiple disputes involving "users claiming lost items" through the unlocking record tracing function, significantly enhancing customer satisfaction. In conclusion: The essence of intelligent security is to "reduce costs and increase efficiency" The innovation of the battery-free NFC smart disc padlock lies not in the accumulation of complex functions, but in precisely addressing the "pain points" of traditional locks - eliminating maintenance hassles with a battery-free design, simplifying permission management with remote authorization, and ensuring safety and compliance through record tracing. ​ If you are struggling with "disorganized key management, cumbersome battery replacement, and no security records", why not give this product a try, which redefines the "smart padlock". Send us a private message now, and you can receive a free sample for testing, experiencing the new security experience of "one-touch unlocking, remote controllability, and full traceability".

In industrial equipment, distribution boxes, control cabinets and other scenarios, cam locks are the core components for safeguarding the security of internal components, and industrial passive cam locks have become the preferred solution in the field of industrial security by virtue of the characteristics of “battery-free, highly adaptable, and strong durability”. Behind its seemingly compact body lies a subtle design principle and rigorous mechanical structure, and it is the integration of these technical details that allows it to play a stable role in complex industrial environments. Passive drive: the core design principle of energy self-sufficiency The “passive” characteristic of the industrial passive cam lock is the most essential difference between it and traditional electronic locks, and the core lies in the design logic of energy acquisition and conversion. It does not require a built-in battery, but rather realizes energy transfer through RF signals emitted by external authorized devices (such as dedicated card readers and cell phone NFC modules) - when external devices are close to the lock's induction area, the coil inside the lock will convert the RF signals into electricity, instantly activating the internal circuitry and completing the identification and unlocking command execution. This design not only solves the problems of battery leakage and lack of battery life, but also synchronizes the service life of the lock with that of the device. In order to realize efficient energy conversion, the induction coil is made of multi-stranded enameled wire, together with the magnetic core focusing magnetic field, to ensure that the energy can be stably obtained within the induction distance of 1-3 cm, and even in the industrial environment covered with grease and dust, the identification success rate can be maintained at more than 99%. Mechanical structure: dual consideration of security and adaptability 1. Cam assembly: the “execution terminal” of precise transmission Cam is the core execution part of the lock, and its shape design directly determines the locking range and the way of force. The cams of industrial passive cam locks are forged from 45-gauge steel, with a hardness of HRC40-45 after heat treatment, and are able to withstand long-term torsional force without deformation. According to different application scenarios, the cam can be designed as a word, L-type, T-type and other forms, for example, the L-type cam is commonly used in the cabinet door of the distribution box, which realizes the linkage of “latch retraction - cabinet door compression” through 90-degree rotation to ensure that the cabinet door and the cabinet are closely fitted with the dustproof and waterproof performance of IP65 level. The connection between cam and lock cylinder adopts keyway structure, and the coaxiality error of the two is guaranteed to be no more than 0.02mm through precision machining, so as to avoid jamming when rotating. At the same time, the cam sleeve is equipped with oil bearing to reduce the friction coefficient, so that the unlocking torque is controlled at 3-5 Nm, which not only meets the demand of labor-saving operation, but also can judge the lock status through the torque feedback. 2. Lock cylinder system: the “security center” of anti-picking and anti-theft The lock cylinder is the key carrier of security performance, and the industrial passive cam lock adopts the dual protection structure of “electronic verification + mechanical locking”. At the electronic level, the built-in encryption chip stores the unique identification code, and each time the lock is opened, the three-step process of “key exchange - identity verification - command authorization” must be completed, and when the verification fails, the lock cylinder will trigger the self-locking, and even if the violent rotation can't drive the cam. Mechanical level, the lock cylinder shell is made of zinc alloy die-casting molding, the internal anti-drilling steel ball and blade anti-prying structure -- when encountered with drilling, prying and other violent damage, the steel ball will be stuck in the rotation of the lock cylinder, and the blade through the staggered design to prevent foreign objects from reaching in. The gap between the lock cylinder and the lock body is controlled within 0.05 mm, which not only ensures smooth rotation, but also prevents dust and moisture from intruding into the internal circuitry. 3. Shell and mounting structure: adapt to the industrial environment of the “protective armor” shell as a lock “first line of defense”, using stainless steel 304 material molded in one piece, the surface by the brushed treatment, both corrosion resistance and can avoid Reflective interference operation. For different installation scenarios, the lock body is designed with a panel type, embedded two installation methods: panel type through four M4 screws fixed to the surface of the equipment, suitable for thickness of 1-3 mm thin cabinet; embedded countersunk head design, the lock body is embedded in the equipment reserved holes welded fixed for thick-walled metal cabinets, installed flush with the surface of the equipment, reducing the risk of damage to the bump.

For frequent maintenance scenarios, the lock can also be equipped with emergency unlocking holes, through a special mechanical key to realize emergency operation in the event of a power failure, taking into account the intelligent and emergency needs. Design Logic: Targeted Optimization for Industrial Scenarios The design of industrial passive cam locks always revolves around the two core elements of “reliability” and “adaptability”. For example, in vibration environments (such as machine tool control cabinets), the lock body is equipped with a damping washer, which absorbs high-frequency vibration energy and prevents the internal parts from loosening; in low-temperature environments (such as cold storage equipment), the circuit components are selected as wide-temperature models, which ensure that they can still work normally at -30℃. The synergistic design of its mechanical structure and electronic system embodies the effect of “1+1>2” -- electronic verification ensures the accuracy of authorization, the mechanical structure guarantees the physical protection, and passive technology eliminates the maintenance pain point. The passive technology eliminates maintenance pains. This design allows industrial passive cam locks to be adapted to different specifications of industrial equipment, but also to maintain stable performance in harsh environments such as oil, moisture, vibration, etc., making it a model of “less maintenance, high reliability” in the field of industrial security. From the subtle design of energy conversion to the rigorous layout of the mechanical structure, every detail of the industrial passive cam lock shows a deep understanding of the needs of industrial scenes. It is not only a lock, but also a product of the fusion of mechanical engineering and electronic technology, which provides both technological and practical solutions for the safety management of industrial equipment.

In industrial equipment, commercial buildings, public facilities and other scenarios, the rotary handle lock is the core component that controls the opening and closing of the door, and its safety and convenience directly affect the overall management efficiency. With the onset of the wave of intelligence, the traditional rotary handle lock is undergoing a profound transformation, and the emergence of passive electronic rotary handle lock is the key breakthrough in this transformation. The operation of traditional rotary handle locks relies on a purely mechanical structure, and key management is a major problem - a large number of keys can be easily confused, the cost of replacement is high after loss, and it is not possible to accurately control the locking privileges of different people. In the scenario of multiple people using the lock alternately, there is no way to trace who opened the lock at what time, and it is difficult to define the responsibility in the event of a security problem. In addition, after long-term use, the mechanical parts are prone to wear and tear, jamming, which not only affects the feel of the operation, but also may lead to the failure of the lock, which brings a lot of trouble to the daily management. The emergence of passive electronic rotary handle lock completely breaks the limitations of traditional locks. From the security point of view, it abandons the traditional key, adopts encryption chip and induction technology, and authorizes unlocking by means of special card, cell phone NFC, etc. Each authorization carrier can independently set the scope of authority and the time limit, which effectively avoids the risk of key exfiltration and copying. What's more, each unlocking action will be recorded in the system in real time, forming a traceable operation log, so that managers can clearly grasp the use of locks through the background, so that security management can be based on evidence.
