Introduction This is a high-quality electric solenoid lock with steel-made case and steel casting parts. Connection Diagram. These types of door locks are used extensively in remote security access and automotive doors. Most door locks work in one or two basic ways. In the case of access doors in buildings, a latch or pins in the lock mechanism located in the door leaf are pushed into a hollow compartment or socket in the frame, thereby preventing the door from being opened.
A fairly simple cam arrangement allows the latch to be withdrawn and retained in the lock mechanism when the door is unlocked. Car door locks usually function in a slightly different manner and feature a slotted cam which locks over a latching bar on the car body. An arrangement of levers and linkages is used to lift the cam and open or lock the mechanism. The solenoid door lock, on the other hand, makes use of a static wire wound coil and a moving armature or plunger to perform the work of the key and linkages in conventional locks.
The power-on locking type can lock a door while the solenoid is powered on. If the power is disconnected, the door is unlocked. This type unlocks the door in case of wire disconnection due to a fire or accident, and it is used for emergency exits through which fire-fighting activity or evacuation should preferentially be made rather than safety for crime prevention.
The keeping type performs two operations, locking and unlocking by applying a positive or negative pulse voltage to the solenoid, and keeps the no-power state in each position. This type features energy saving because it is unnecessary to always power the solenoid on.
