There are two main types of electric locking devices.
How does electromagnetic gas door lock work.
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.
Typically the electromagnet portion of the lock is attached to the door frame.
This energy field is transmitted through the lock and it creates a repelling effect on those trying to gain access.
An electromagnetic lock magnetic lock or maglock is a locking device that consists of an electromagnet and an armature plate.
When current flows through the electromagnet it creates a strong magnetic field attracting the relatively large surface of the armature plate on the door.
Fail safe locking devices are unlocked when de energized.
Apply battery backup power supply to individual door locks to solve power outages and enable 24 7 electricity supply.
The magnetic field is strong enough to prevent the door from being forced open requiring a user to input a security code or present a badge to deactivate the electromagnet and free the door.
Direct pull electromagnetic locks are inherently fail safe.
Typically the electromagnet portion of the lock is attached to the door fram.
Thinner cables are not sufficient to carry power all the way from the power source to the door lock.
Locking devices can be either fail safe or fail secure.
Electromagnetic door locks electromagnetic door locks work by sending an electromagnetic field through the interior of the door that repels the entry of a person who tries to open the door with the use of a key.
As they require power to remain locked this allows them to be fail safe making electromagnetic door locks safe for use as emergency exits.
A fail secure locking device remains locked when power is lost.
Direct pull electromagnetic locks are inherently fail safe.
