·IP67 grade protection.

·Triple sealing structure (silicone sealing ring + dust cover + nano-coating), effectively blocking rain, dust, oil intrusion (through GB/T 4208 anti-flush water test)

· latch is made of 304 stainless steel, with a corrosion-resistant life of more than 5 years in coastal salt spray environment.

3. Intelligent management: one key to open + data traceability

· authorization hierarchy system.

· single electronic key can manage 200 + control box locks, support hierarchical authorization (such as operation and maintenance personnel can only open the jurisdiction of the area 50 locks)

· After docking with IoT platform of Transportation Bureau, it can record the locking time, operator and equipment status in real time, and the abnormal locking automatically triggers SMS alarm.

· is quick to install and adapt.

· supports the installation of 35mm/45mm standard control box profiles, replacing old locks in 15 minutes without destroying the box structure.
