Stainless steel passive lock accessories casting hardware parts with polished

Passive electronic lock is a new important branch in the field of electronic locks. The biggest difference between it and traditional electronic locks The necessary working power of the lock is moved to the electronic key (called active electronic key), which completely solves a series of inherent problems in traditional active electronic locks, such as: consumes a lot of batteries and requires frequent maintenance. Complex structure, generalization, low standardization, and high failure rate.

The shape, volume and installation method of passive electronic lock cylinders are equivalent to those of standard mechanical locks, which can directly replace (exchange) general mechanical locks. The electronic lock cylinders installed on general mechanical lock bodies are "passive electronic locks". The core component is the "digital switch" that is directly upgraded from general mechanical locks to electronic locks.

working principle

When the "active electronic key" is in contact with the "passive electronic lock", the power source (battery) and the unlocking electronic code on the "active electronic key" are simultaneously imported into the "passive electronic lock" of the built-in microcomputer. If it meets, the lock can be opened.
