How Do Electromagnetic Locks For Doors Work
Most cases the armature plate is on the edge of the door while the electromagnet is wired to the.
How do electromagnetic locks for doors work. As they require power to remain locked this allows them to be fail safe making electromagnetic door locks safe for use as emergency exits. The magnet itself is designed with an electrical coil which when powered creates a strong electro magnetic field which is how maglocks can offer such impressive holding forces. Locking devices can be either fail safe or fail secure. Fail safe locking devices are unlocked when de energized.
A mag lock is a type of automatic lock which simply takes advantage of this controllable magnetic property. When a magnet connected to a door s frame gets energized by current flowing through the coils the door is locked. The magnetic field is so strong that the force secures door and keeps it from being opened. An electromagnetic lock magnetic lock or maglock is a locking device that consists of an electromagnet and an armature plate.
Typically the electromagnet portion of the lock is attached to the door fram. How does an electromagnetic lock work. Direct pull electromagnetic locks are inherently fail safe. When the electromagnet is energized the armature plate is attracted to it.
In simple terms maglocks work by magnetically adhering to a metal counterplate called the armature plate. Magnetic locks are keyless and its locking effect is controlled by the solenoid or the electromagnetic strip. A fail secure locking device remains locked when power is lost. This means of course that maglocks require power to lock.
This is achieved by the armature plate attached to the door.
