Under the wave of new retail, vending machines have become the “capillaries” of the retail industry by virtue of the advantages of 24-hour unattended operation and strong scene adaptability. However, equipment safety and maintenance problems in extreme environments have always plagued operators -- low temperatures lead to battery failure, high temperatures trigger lock failures, and humid environments cause rust and corrosion ...... Traditional electronic locks are “not suited to the soil and water ”, making the reliability of unmanned retail scenarios much less reliable. Zinc alloy industrial passive electronic locks break the ice with industrial-grade hardcore performance. With -25℃~+65℃ wide temperature adaptability and passive power supply technology , it creates an all-weather security line of defense for vending machines and redefines the durability and stability of industrial locks. Industrial grade zinc alloy material: anti-build and weather-resistant, suitable for complex scenes Vending machines are often deployed in outdoor, cold chain warehouses, industrial plants and other environments, where the locks need to withstand temperature shocks, humidity, dust and even minor impacts. Traditional plastic or ordinary metal locks are prone to aging and deformation, while zinc alloy industrial passive electronic locks use high-strength zinc alloy die-casting molding, through three core advantages to deal with industrial-grade challenges: 1. Corrosion-resistant plating process, no rust in humid environment Surface by multi-layer nickel-chromium plating treatment, the formation of dense protective film, salt spray test up to 72 hours (far more than ordinary locks 48 hours standard), even in the rainy season in the south or coastal high humidity scenarios, the lock body can still maintain smooth opening and closing, to eliminate the rust caused by the lock, hard to open and other issues. 2. Stable operation in wide temperature, no deformation in extreme temperature difference. Through -25℃ low-temperature cold shock and +65℃ high-temperature durability test, the coefficient of thermal expansion of zinc alloy material is as low as 27×10-⁶/℃, so that the lock body structure does not shrink or deform in both hot and cold environments (e.g., outdoor in winter in the north and on the street in hot summer in the south), which ensures that the electric circuitry and mechanical parts work together in a stable manner and avoids poor contact or jamming phenomenon due to the temperature difference. 3. High-strength impact resistance, resisting external damage Zinc alloy hardness of HB80-100, better than ordinary aluminum alloy (HB60-80), can withstand 100N・m torque destructive force, effectively resist lock picking, impact and other violent acts, to provide a physical layer of security for high-value goods (such as electronic products, medicines) in the vending machine. Passive power supply technology: goodbye to batteries, cost reduction and efficiency double breakthroughs Traditional electronic locks rely on battery power, not only need to be replaced regularly (20% increase in the average annual maintenance cost of a single device), but also due to battery leakage, low-temperature power outages may lead to lock failure, resulting in cargo damage or user complaints.

Operators do not need to replace batteries for hundreds of devices one by one, and the amount of equipment that can be maintained by a single person in a single day can be increased by 5 times, significantly reducing the cost of labor and consumables. 2. Electromagnetic compatibility design, reject signal interference Zinc alloy shell naturally shield electromagnetic interference, combined with the EMC electromagnetic compatibility design of the lock circuit, even if installed in a high-frequency electromagnetic environment (e.g., next to the factory switchboard box), can prevent false triggering or signal disruption, to ensure that the unlocking logic is 100% reliable. -25 ℃ ~ +65 ℃ limit test: data to verify durability To ensure stability in extreme environments, zinc alloy industrial passive electronic locks have passed three stringent tests. 1. High and low temperature cycling test After 24 hours of standing in -25℃ environment, immediately transfer to +65℃ high temperature box for 12 hours, repeat 50 cycles. Tests show that: the lock body mechanical parts wear rate <0.1%, the circuit response time to maintain ≤ 0.3 seconds, far exceeding the industry standard (ordinary locks in - 10 ℃ below the response delay increased by 30%). 2. Humidity alternation test Running in 85% RH high humidity environment for 30 days, no rust spots on the surface of the lock body, the insulation resistance of the internal circuit board>100MΩ, fully meet the moisture-proof requirements of the rainy season and cold chain storage in the south. 3. Drop impact test The lock body has no cracks and functions well after 10 falls from 1.5 metres to the concrete floor, which is suitable for the accidental collision scenarios during the transportation and installation of vending machines. Exclusive solutions for vending machines: double upgrading of safety and efficiency For unmanned retail scenarios, zinc alloy industrial passive electronic locks provide three core values. 1.

After deploying passive electronic locks, the battery-free design and low-temperature-resistant zinc alloy material realized 3 consecutive years of zero failure and reduced maintenance costs by 85%. · Photovoltaic power plant in Saudi Arabia: Faced with high temperatures of +65°C and sand and dust, a brand of passive electronic locks reduced the failure rate of the distribution box from an average of 42 times per year to 2 times per year, thanks to IP68 protection (no leakage after 24 hours of 1-meter underwater immersion) and a nano-ceramic coating. Core Advantage: · Battery-free design completely gets rid of temperature dependence; Military-grade materials resist impact and corrosion, adapting to extreme working conditions. Scenario II: Cross-border logistics -- “security guards” for container transportation Data testimonials: · Maersk Asia-Europe route: after deploying passive electronic locks, the number of container theft incidents plummeted from an annual average of 300 to 8, with a 100% detection rate (the locks keep complete locking records); DHL Southeast Asia route: 5,000 locks are managed by one electronic key, logistics personnel's key chain is streamlined from 30 strings to one, and the efficiency of container handling is increased by 50%. Technical Highlights: ·AES-256 financial-grade encryption, anti-technology crack; · Real-time monitoring of abnormal opening, triggering a cloud-based alarm within 3 minutes. Scenario 3: Intelligent Warehousing -- “Intelligent Hub” for Rights Management Benchmark case: · Amazon Europe FBA Warehouse: Adopting passive electronic locks with mobile APP authority management to realize “one person, one authority, one time period, one authorization”, and the rate of lost items in the warehouse decreased by 92%; Australia Cold Chain Logistics Center: In the low temperature environment of -25℃, the battery-free feature of passive electronic lock ensures that the door lock of the cold storage is always available and avoids the loss of goods due to battery failure. User comment: “It takes only 15 seconds to adjust the rights, and the operation records are traced in real time, which completely solves the confusion of traditional key management.” -- IT Director of a German logistics company Scenario 4: Public Facilities -- The “Invisible Guardians” of Urban Infrastructure Application Fact Sheet: · London Underground Power Distribution System: Passive electronic locks are certified by EN 50155 Railway Transportation and have been in continuous service for 5 years without failures in wet tunnel environment, ensuring the safety of the subway power system; · Dubai Smart City Project: Managing 2000+ outdoor power distribution boxes, the locks are subject to more than 10 switching operations per day, and the 10-year maintenance-free design saves millions of dollars in O&M costs. Technical support: · Fully sealed construction dust and water resistant (IP66+); · Resistant to 10J energy impact (against violent damage). Scenario 5: Scientific Expeditions -- “Reliable Partners” in Polar Environments Extreme challenges: · Antarctic Research Station: In temperatures as low as - 40°C and strong winds, the passive electronic lock ensures that research equipment is accessible at all times, thanks to its low-temperature-resistant zinc alloy and adaptive structure (bimetal sheet to compensate for thermal expansion and contraction); · Amazon Rainforest Survey Project: In response to high humidity and insect infestation, the lock's IP68 protection and nano-coating technology prevents short circuits and mechanical jamming. User Testimonial: “After 3 years of continuous work in Antarctica, the locks have never failed due to environmental factors, providing a solid guarantee for research missions.” -- Engineer at an international polar research organization Data speaks for itself: a summary of the core values of the 100+ program Dimension Traditional Solutions Passive Electronic Lock Program Enhancement Effect Burglary Loss Average annual theft rate 5%-8% Down to 0.1%-0.5% Reduced by more than 90 Operation and Maintenance Costs Average annual maintenance cost $200 per handle 10 years maintenance free, only purchase cost Reduced by 80% or more Response Efficiency Temporary authorization requires human presence (30 minutes +) Mobile APP remote authorization (within 5 minutes) 83% improvement Failure Rate 3-5 failures/handle per year Reduced to 0.1 failures per handle 98% reduction With 100+ successful overseas projects, Passive Electronic Lock proves that it is not only a lock, but also a set of security ecosystem covering all scenarios.
