AS 0854 DC 12V Electromagnetic Solenoid door Lock for home or office application
Working principle of electromagnetic door lock
The smart electromagnetic door lock for cabinets works on the electromagnetic principle, similar to an electromagnet/DC solenoid valve. When current passes through the electromagnetic coil in the lock body, a strong magnetic force is generated. This magnetic force attracts the adsorption iron plate to achieve the effect of locking the door.
Control circuit: The control circuit is the core of the smart electromagnetic door lock, usually based on a microcontroller such as a single chip microcomputer. It is responsible for receiving and processing various input signals, such as unlocking instructions from a fingerprint recognition module, password input, or RFID card reader. The control circuit also controls the opening and closing of the electromagnetic lock, and some models can also record access logs and perform other functions.
Power supply: Provides the necessary power for the operation of the lock. It can be connected to the mains through a power adapter or powered by batteries. Some smart electromagnetic door locks are also equipped with a backup power supply device to ensure normal use during power outages.
