An example of a local estimate for the installation of an electromagnetic lock. Installation of an electromagnetic lock (EML)
The most important characteristic electromagnetic device is the force of its separation. This indicator may vary from 150 to 1200 kg tensile strength, despite the fact that the average person is not capable of creating forces greater than 120 kg. Therefore, connecting an electromagnetic lock to metal door or any other is a good solution.
Magnets with the weakest adhesion are generally used for interior doors. Installing an electromagnetic lock on the entrance door, due to safety reasons, should be carried out with a minimum lift-off value from 600 kg.
EMZ differ:
- type of locking;
- type of control.
These two species are in turn divided into subspecies. So, in case of locking they are sliding And holding.
By type of control: with Hall sensors(require additional power supply) and Reed switch elements(no need to supply constant energy).
EMZ protection methods
To ensure maximum durability of the lock, a certain protective coating must be applied to the working surface.
The following methods exist:
- The most economical option for preserving a lock is to varnish it. This method is not the best, since with temperature changes and frequent precipitation, the entire varnished layer comes off, resulting in the formation of rust and corrosion.
- When galvanizing the surface, the service life increases significantly, since external factors cause minimal harm.
- If you use nickel for protection, then you can completely avoid various types of repair work.
When installing electromagnetic locks and using them, there are some tricks and tricks that in the future will help make the operation as complete as possible, without damage and other unpleasant moments.

The task of restricting access to a separate office inside a large office is simple technical solution– it is enough to install a card/key reader, a controller (control unit) with a power supply on the outside of the cabinet, and an electromagnetic lock on the door with a closer, and an “exit” button inside the cabinet.
How does it work single door access control system with an electromagnetic lock? Firstly: those who do not have access will not be able to get into the office/office on their own without using a crowbar and other tools. Secondly: the remaining small group persons who have access and, accordingly, have electronic keys or access cards, can easily open the door by presenting their card to the reader. When the card is brought to the reader, a special controller checks whether it is written into memory and if so, the electromagnetic lock turns off for a few seconds, at which point the system emits a sound signal so that the person can orient himself and open the door in time.
