What does Electromagnetic lock mean?

An electromagnetic lock, also known as a magnetic lock, is designed to use the principle of electromagnetic induction to open and close doors. The current electromagnetic lock does not have a complex mechanical structure and is therefore ideal for use in secure access doors, such as escape doors, fire doors, and other areas. Electromagnetic locks are currently used not only in areas such as fire doors but also in outdoor areas such as electrical installations. Shop electromagnetic locks can be divided according to their functionality into indoor electromagnetic locks, electromagnetic knife locks, DSW outdoor electromagnetic locks, and DSN(W)3-J grounded electromagnetic locks.

The working principle of the Electromagnetic lock.

Electromagnetic lock uses the principle of electromagnetism, when there is a current through the silicon steel sheet, electromagnetic lock will produce a huge attraction and only suck the iron plate to achieve the effect of locking the door. When the access control system controlling the electromagnetic lock is subject to the induction of the access card, the power will be cut off and the Electromagnetic lock will lose its attraction and open the door.

The strength of attraction of the electromagnetic lock is currently measured in pounds and is obtained by static pressure. Static pressure is when the electromagnetic lock is energized and slowly increases the pulling force on the magnet, when the suction force of the office electromagnetic lock is exceeded the pulling force of the iron plate is instantly released, then this value is the pulling force value of the Electromagnetic lock.

Can the Electromagnetic lock be broken with a magnet?

The electromagnetic lock cannot be broken with a magnet. Generally, there are two ways of unlocking an electromagnetic lock, one is by power failure and the other is by power. When using the power-off unlocking method, the door is opened as soon as the power to the apartment electromagnetic lock is switched off. For electromagnetic locks, there are usually two wires in a concealed area and the lock will be opened when 5V or 12V (depending on the lock model) is connected to the wires.

The design of the electromagnetic lock is the same as that of an electromagnet, generally using the principle of electromagnetism. As long as a small current electromagnetic lock will produce a great magnetic force, control electromagnetic lock power access control system to identify the correct person that power off, hotel floor electromagnetic lock lose suction can open the door.
