How Do Electromagnetic Locks For Doors Work

Magnetic locks are keyless and its locking effect is controlled by the solenoid or the electromagnetic strip.

How do electromagnetic locks for doors work.

Locking devices can be either fail safe or fail secure. A mag lock is a type of automatic lock which simply takes advantage of this controllable magnetic property. The magnetic field is so strong that the force secures door and keeps it from being opened. How does an electromagnetic lock work.

Most cases the armature plate is on the edge of the door while the electromagnet is wired to the. An electromagnetic lock magnetic lock or maglock is a locking device that consists of an electromagnet and an armature plate. An electromagnetic lock creates a magnetic field when energized or powered up causing an electromagnet and armature plate to become attracted to each other strongly enough to keep a door from opening. This means of course that maglocks require power to lock.

Fail safe locking devices are unlocked when de energized. As they require power to remain locked this allows them to be fail safe making electromagnetic door locks safe for use as emergency exits. This is achieved by the armature plate attached to the door. 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.

In simple terms maglocks work by magnetically adhering to a metal counterplate called the armature plate. Typically the electromagnet portion of the lock is attached to the door fram. A fail secure locking device remains locked when power is lost. Direct pull electromagnetic locks are inherently fail safe.

When a magnet connected to a door s frame gets energized by current flowing through the coils the door is locked.
