AS 0946 Frame Type Solneoid DC 12V Long stroke Distance For Smart Door Lock System

Working Principle of Smart Door Lock

The smart door lock consists of two parts: the solenoid valve and the lock body. The solenoid valve generates a strong electromagnetic force when the current passing through the solenoid coil, pushing the iron core ( plunger ) to move linearly, and pushing the lock tongue to the door frame to achieve the extension and retraction control of the smart lock . When the power is off, the magnetic force on the solenoid valve disappears, and the lock tongue will return to its original working position by the force of spring.  

 

Due to different designs, electromagnetic door locks are also divided into two types, normally open and normally closed style.

The normally open electromagnetic lock, also known as the power-off unlocking electromagnetic lock, opens when the solenoid valve is powered on. When the solenoid valve is out of power, the lock body is closed.

The normally closed electromagnetic lock, also known as the power-off locking electromagnetic lock, closes when the solenoid valve is powered on. When the solenoid valve is out of power, the lock body is opened.

Both types can be implemented in practical applications and can be set according to actual needs.

  • Working voltage: it usually works on DC12V or 24V DC, low power consumption design (current about 200-500mA).
  • Action time: extremely fast response speed (<50ms), suitable for instant unlocking needs.

 Design

The three-level conversion of electrical energy → magnetic energy → mechanical energy depends on the coordinated optimization of coil turns, current intensity and core material (such as soft magnetic alloy).

PRODUCTS DETAILS

 Product Description:

It is know that solenoid is basically electromagnet, built in a big coil of copper wire with an iron armature in the center of housing. Once the solenoid coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull from one end.


This kind of solenoid is nice and strong as it has a slug with a slanted cut and a good mounting bracket. Basically, it is an electronic lock. Normally the lock is active so you can't open the door because the solenoid slug is in the way. It does not use any power at this state. However, when 9-12VDC is applied, the slug pulls in and the door can be opened.
