Electro-magnetic lock with handles
No Moving parts makes for these locks to be ideal, Magnetic locks use electromagnetism to control the entire locking mechanism. When the magnet is energized, it bonds to the armature and locks the door. To allow access or egress, a switch is activated via keypad, push button which de-energize the magnet and allows a person to enter . It uses less the a night light.
The current is around
0.5 A when the voltage supply is 12VDC
and 0.25A when using 24VDC
