Electromagnetic door lock is an innovative move of modern technologies in the field of security and protection of your rights and interests from unauthorized access to your personal territory.
Magnetic locks provide a high level of security due to their reliability and durability. These indicators are ensured due to the features of the lock itself and proper installation. Professionally installed modern electromagnetic locks hold even heavy metal doors. When ordering an electromagnetic lock with installation from us, you can be sure of its quality, reliability and durability. The price of a turnkey solution is 9900 rubles.
This type of locking device has advantageous characteristics due to the absence of rubbing mechanisms and parts in the body itself, which guarantees:
- High percentage of operational reliability.
- Increased wear resistance.
- Durability.
If we talk about the principle of operation of this type of device, then it is quite simple and practical, but only on the condition that the connection was made by experienced specialists. The door is kept closed thanks to the action of a powerful lock consisting of a winding and a core. After the door is closed, the unit connected to electricity begins to generate magnetic fields that are responsible for holding the strike plate. To separate the plates, you will have to make superhuman efforts, the component of which varies from 60 kilograms to 2 tons.
When the current is turned off (this option is controlled by a controller that instantly responds to a radio signal or a contact key), the magnetic fields release the plate, and this is the only way to open the electromagnetic lock.
Electromagnetic locks are devices that hold doors closed using a strong electromagnet on one leaf and an iron plate on the second leaf. It is appropriate to install them on the doors of rooms where a large number of people enter every day. First of all, we are talking about the offices of trading companies and industrial enterprises, supermarkets and hotels, and simply about the entrances of residential buildings. Electromagnetic locks have received particular recognition when arranging premises belonging to various business structures. Their use makes it possible to significantly improve control over the efficiency of employees’ use of working time, discipline, streamline the system for receiving visitors, etc.
Most conventional door locks wear out quickly when there is high traffic, but electromagnetic ones last a long time due to the fact that they simply do not have parts that could wear out from frequent use of the door. The devices are easy to use and, in addition, when installing locks it will cost the buyer less than, for example, an electromechanical one. And the installation process itself will take less time.
What to look for when choosing an electromagnetic lock
When choosing a magnetic lock, you should start from the type of door. So, for lightweight wooden or plastic sheets, compact locking devices with low power are suitable. The force to pull off such locks should be in the range of 150-200 kg. For metal entrance doors, more powerful devices are recommended that can withstand a load of 300 kg or more. For glass doors, there are sliding-type magnetic lock models that help avoid unwanted damage.
For swing doors, it is recommended to choose a lock with a door leaf position sensor. This will allow the lock to “understand” that the door is in the desired position and can be locked. Ordinary swing doors do not need such sensors, since they are equipped with an automatic closer.
When purchasing a magnetic lock, you also need to take into account a number of factors that affect the cost, such as:
- design features of the door;
- integration with the access control and management system (ACS);
- climatic conditions;
- features of the point of passage for visitors;
- fire safety requirements.
Design and principle of operation
The design of an electromagnetic lock (EML) is relatively simple. The main elements of the device are a core with a coil located in the housing. Most often, the core is made of transformer steel, which reduces residual magnetization when the lock is opened. A special paint coating is also used for this. However, this does not allow achieving complete elimination of accumulated energy.
In most electromagnetic locks, the core is a set of plates connected in the shape of the letter “W”. However, there are devices in which this element has a one-piece design. This solution has one significant drawback: the residual stress accumulates quite intensively. To eliminate this negative effect, a capacitor with a capacity of at least 200 μF is introduced into the design.
In this video you will learn how to install an electromagnetic lock:
To make a winding with a large number of turns, a copper conductor coated with enamel is used. The lock body material is most often aluminum or stainless steel. You can also find plastic devices on the market, but they break down relatively quickly. The operating principle of an electromagnetic lock is not very complicated.
Voltage is supplied through the terminals to the coil and housing. As a result, the magnetic elements of the device are activated and the EMZ is closed. When the voltage is removed, an oscillatory circuit with alternating current is created. The presence of a capacitor in the design allows the discharge process to be carried out through the core winding and its polarity changes, which leads to the opening of the device. The residual current is sent for magnetization reversal.
Some locks are additionally equipped with Hall sensors, which allow them to respond to the position of the locking mechanism and the closing of the door leaf. Using such a sensor, you can find out whether the door is closed and how many people have passed through it. In addition, thanks to them, security increases, since it is impossible to open the lock using standard master keys.
Optional equipment
For stable operation of magnetic locks, it is recommended to install a door closer. This affordable device automatically closes the door at a preset speed and closing force. Another advantage of the closer is the extension of the service life of the lock due to the smooth and accurate closing of the door.
Since the magnetic lock requires a continuous supply of electricity to operate, it is a good idea to install an uninterruptible power supply. Autonomous batteries will allow the lock to operate normally for quite a long time.
The principle of operation of a magnetic lock is as simple as possible: when voltage is applied to a powerful magnet, an electromagnetic field appears, which tightly holds the counterpart (anchor) attached to the door leaf. As soon as the power supply is stopped, the door can be opened without much effort.
Connecting the power supply
Power supplies must be installed indoors with optimal temperature parameters (from +5 degrees Celsius) and humidity (up to 92%).
The power supply must be connected to the controller terminals, the actuator (electric lock) and the reader.
How to connect the electromagnetic lock and reader will be discussed in the following sections of this manual.
To connect the power supply to the controller, you must use the following terminals on the board:
Connect the << + >> power supply to the << power >> terminal.
<< - >> connect the power supply to the << ground >> terminal.

How to choose a magnetic latch for a balcony door
Often the balcony door is equipped with a handle on only one, inner, side, and a so-called smoker’s handle is installed on the balcony side. While outside, you need to pull it so that the canvas is pressed against the frame. Because of this feature, it is best to install a magnetic latch with a passive mechanism on balcony doors. It does not require a handle to operate.
It is necessary to select fittings in accordance with the size of the door, taking into account:
- length of the mortise part;
- the width of the slats, which should be less than the width of the door end;
- magnetic tongue size.
Magnetic fasteners are durable and do not require special care. It is enough to periodically wipe the outer parts. Over time, the mounting screws may become loose. The problem is solved by tightening it tightly with a screwdriver. The mechanism can fail only when the magnetic parts are demagnetized, which happens very rarely.
The reliability of the magnetic lock depends on the manufacturer. To guarantee the purchase of a quality product, it is recommended to give preference to trusted brands (Roto, Kale, Apecs, Winkhaus). And also make sure that the product has the necessary certificate of conformity.
Using electromagnetic locks in access control systems
Access control and management systems are an integral attribute of offices, shops, banks and most government agencies. To ensure an increased level of security, additional video cameras can be used in conjunction with magnetic locks to provide a clear image of the visitor.
Magnetic locks fully meet stringent fire safety requirements. If there is a power outage in emergency situations, the lock automatically switches to the “open” mode, ensuring free passage.
To gain access to a room or, more simply, to open a lock, special tablet keys, key fobs, Proximity cards, keypads and even biometric fingerprint scanners are used.
Selecting a cable to connect
To supply power to the lock and controller with a line length of up to 50 meters, it is recommended to use the ShVVP 2*0.5 electric cable. This is a connecting wire consisting of 2 copper wires.
If the line length exceeds 50 meters, then you should use the ShVVP 2*0.75 cable.
To connect the exit button, reader and other devices, you need to use a UTP (unshielded twisted pair) or SHVP cable.
To avoid short circuits, it is necessary to reliably insulate all connections, best of all with heat-shrinkable tubing.
Positive qualities of EMR

- do not give in to attempts to open them with master keys;
- provide safety during fires, since they open automatically when there is a power outage, allowing people to leave all premises;
- Doors on which an electromagnetic lock is installed cannot be opened by an attacker without the use of special powerful technical means, since it is capable of withstanding forces reaching several hundred kilograms.
Connecting the exit button
The exit button makes it possible from inside the room to unlock the electromagnetic lock installed on the door at the right time.
The exit button should be connected according to the following diagram:
Connect the << first >> button wire to the << Button >> terminal.
Connect the << second >> wire to the << Ground >> terminal.
If connected correctly according to this diagram, when you press the exit button, the door will open for the temporary period set in the controller. Default 5sec
