What is the solenoid door lock?
Solenoid door lock is a remote door lock that is captured or opens with electromagnetic solenoid. In most cases, the actual locking mechanism of solenoid door lock will be identical to the conventional example controlled key. The only difference between them is the inclusion of low voltage solenoid into a mechanism that attracts the latch back into the door when a button or other driver is activated. The latch will then be detained in the door as long as the button is pressed, or in the case of solenoid latch, indefinitely until the button or controller is re -activated. These types of door locks are widely used in a remote safety approach and car doors.
Most door locks work in one or two basic ways. In the case of access doors in buildings, the latch or pins in the lock mechanism located in the door are pushed into the hollow space or drawer in the frame to prevent the door from opening. Relatively simple easement e camIt allows the latch to become and preserve in the mechanism of the castle when the door is unlocked. Locks for the car door usually work in a somewhat different way and have a slot that locks over the latch on the body of the car. The arrangement of the levers and the connection is used to raise the cam and open or lock the mechanism.
, on the other hand, the solenoid door lock uses a static coil for the wound and a moving anchorage or piston to perform the work of the key and connection in conventional locks. The coil is connected to a circuit that includes low voltage, direct current power supply (DC) and at least one control input, such as a button. When the inspection is activated, the electric current flows into the coil, it energizes and creates a strong magnetic field around it. This magnetic field attracts an armature or piston, causing it to move quickly towards Coil. The latch or cam mechanism of locking is attached to the armature orThe piston over the shoulder of the controller and then is pulled from the location position.
In the case of some safety access doors, the solenoid door lock remains active for a few seconds with the kind permission of the built -in delayed circuit that allows you to open time. It can also be an active operator that holds the control button until the door opens. When the power supply is cut into a solenoid, the latch locks again when closed and the door locks again. If the lock is designed to remain open for a long time, the latch solenoid can be used. These solenoids include a set of permanent magnets at the back of the coil that holds the piston in place, allowing the energy to cut on the solenoid lock coil, preventing overheating and unnecessary energy drainage.
