Magnetic lock, also known as electromagnetic lock, is an electric lock that relies on the suction force generated between an electromagnet and an iron block to close the door.
Some magnetic locks have the output of door status (door magnetic status). If you look carefully at the terminals, in addition to the power terminals, there are also three terminals: COM NO NC. The function of these terminals can be determined according to whether the current door is open or not. When it is closed, output different switch signals to the access control controller for judgment. For example, functions such as the illegal intrusion alarm door of the access control that have not been closed for a long time depend on these signals for judgment. If these functions are not required, the door status signal terminal can be left unconnected.
Magnetic locks are usually used for wooden doors, fire doors.
Advantages: The performance is relatively stable, and the repair rate will be lower than other electric locks. Easy to install, no need to dig the lock hole, just use the wire slot and fix the lock body with screws.
Disadvantages: It is generally installed on the top of the door sill outside the door, and due to the exposure, the aesthetics and safety are not as good as the electric mortise lock installed in a hidden way.
Due to the limited suction power, the usual model is 280 kg force, which may be pulled away by many people at the same time, or people with great strength suddenly pull it apart. Therefore, magnetic locks are usually used in public places such as office interiors.
