Electromagnetic Lock

How the electromagnetic lock works

The design principle of the electromagnetic lock is to use the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction to attract the iron plate to achieve the effect of locking the door. Generally, only a very small current is required to generate a strong magnetic force. Generally, if the electromagnetic lock is opened, only the lock access control system needs to be controlled to identify the person to open the door.


Electromagnetic locks application

The electromagnetic lock is mainly suitable for the interlocking parts of the front and rear cabinet doors of the indoor high-voltage switchgear to realize the interlocking to prevent the occurrence of misoperation, and is an indispensable locking device for the power generation and power supply departments. In addition, some electromagnetic locks also add auxiliary contacts in the lock, and can have corresponding switch contacts in the joint position of the locks, so that the user locks are interlocked with each other.


Note on the use of electromagnetic locks

Be careful not to drill holes in the lock body of the electromagnetic lock, do not replace the fixed important screws, do not wipe the electromagnetic lock with a corrosive cleaning agent, and do not change the circuit. The method of maintaining the electromagnetic lock is very simple, as long as the main surface of the electromagnetic lock is kept clean and the magnet is not corroded.
