An 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.
Advantages and disadvantages
When determining the operating features of electromechanical locking systems, it is necessary to note their convenience. You can lock the gate lock from the inside. So, the person who is outside will not open it even with a key.
Overhead frost-resistant locks
Reliability is the main difference between electromechanical locking devices. A good frost-resistant stainless steel lock lasts a long time without replacement (up to 50 years).
An intercom requires the installation of an electromechanical lock on the gate. Composite elements located in the same circuit help provide control over the area and allow the lock to be closed remotely.
When attaching the equipment, it can be placed in a vertical or horizontal position. Before you buy a locking mechanism, you need to study the rating of these devices, the cost, and the features of fastening to the door profile.
Outdoor electromechanical version
The advantages of installing a lock on the gate are obvious:
- reliability;
- long service time;
- connection to various security systems;
- equipment price;
- use in any situation.

The electromechanical lock is not universal. There are some disadvantages:
- in the event of a breakdown, it takes a lot of effort to open the gate, especially if the upper and lower crossbars are additionally installed;
- a latch that protrudes from the end of the canvas can tear clothing or injure a person passing through the gate;
- it is necessary to organize a constant power supply;
- Failures may occur at high humidity and low temperature (if the lock is not frost-resistant).
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.
Installation of a magnetic lock
Now let’s figure out how to install the structure with your own hands. We will look at the main stage: installing a locking system; you can attach the opening button from the inside and the reader from the outside without our help, because you need to lay a wire and fix the elements on the wall or door frame.
This is what the package looks like:
The work instructions look like this:
| Illustration | Description |
| You need to remove the electromagnet and the metal plate on which it will fix the door leaf from the kit. Carefully inspect the elements, try on the striker plate to the magnetic part to understand how it should be positioned on the door so that the surfaces adjoin each other over the entire area. If there are distortions and a loose fit, the reliability of the system will greatly decrease. |
| We recommend purchasing locks with connectors already installed. This is much more convenient than twisting wires or soldering them. The connector is similar to a regular telephone plug, it is easy to connect and disconnect, it is safe and does not require special electrical knowledge. |
| You will need a drill to drill the holes. If you need to work with concrete, it is better to use a hammer drill with an impact drill. The specific solution is selected depending on what materials need to be drilled, because the walls can be different, as well as the door frames and the trim on them. |
| To take all the necessary measurements, you need a tape measure or ruler of suitable length. A pencil or construction marker is used for marking. Sometimes you may also need a square to accurately transfer marks from one plane to another. |
| To tighten the screws, a screwdriver is used, most often it is a cross-shaped version of PH2. But there may be other configurations, it all depends on the fasteners that come with the package. |
| The hexagon socket wrench is used to secure the lock body. Most often it is included in the kit, but it may not be. Therefore, check the availability of this tool; if it is not, then find it separately, it costs a little. Most often you need the 5 mm option. |
| The easiest and fastest way is to attach the lock to the top of the door leaf. There it does not create much interference, and it is not difficult to install it, since nothing will interfere with the work. Surfaces must be smooth and clean. If you need to paint a door or frame, it is better to do it in advance. |
| The location of the strike plate on the door is determined. Two marks are placed, and the template that comes with the lock is glued to this place. This is a sticker that will be very easy for you to navigate in the future. It will eliminate any deviations in size and ensure accuracy and high speed of work. |
| As you can see in the photo, there are three marks on the sticker. They not only show where the holes are drilled, but also indicate their diameter. You should carry out the work following the tips on the template - everything is very simple. |
| Holes are being drilled. At the edges they have a small diameter - the protrusions on the edges of the plate will go there, which prevent it from turning and ensure the stationary position of the element. A larger hole is made in the middle; it is needed for the fastening screw, which will hold the mating part on the door leaf. |
| The mating part is secured with a screw, which is tightened with a hexagon. The plate is carefully placed so that the protrusions fit into the outer holes, after which it is fastened. It is necessary to fix the element tightly. Tightening is done manually, this is quite enough to ensure reliability; you should not use a power tool, as you can break the thread. |
| When the plate is installed, the mount should be flush with the surface. The element itself fits tightly to the door frame and stands along its line - this is the correct installation option. |
| The housing is placed at the location of the plate. We need to figure out how it will stand on the door frame in order to plan the location of the fasteners and make sure that everything is fine and there will be no problems in further work. |
| A mark is placed on the wire location line. It will be necessary to drill into the structure in this place to pass the cable and hide it from view. |
| The body is pressed tightly against the plate, after which markings are made. It is important that the surfaces touch along the entire length; hold the element tightly during the marking process. |
| A hole is drilled for the cable. For work, use a drill of such a size that you can pull through not only the wire, but also the plug at the end, which is always a little larger. |
| The frame strip is attached to the door frame. It is unscrewed from the structure and fixed to the surface using self-tapping screws that are included in the kit. |
| The lock body is screwed to the bar with four hexagon socket screws. Next, you need to secure the button from the inside and the reader from the outside, after which you can connect the lock to the network. Don't forget to check the functionality of all elements. |
Simple connection of an electromagnetic lock and easy installation
In some cases, installation requires only a regular screwdriver. There are no problems with precise adherence to gaps; distortions during installation have minimal impact. Small errors during installation have virtually no effect on the effective operation of the electromagnet.
Power connection
The final stage of installation is connecting the electrical part. This procedure is quite simple due to the presence of markings. So, the wires with the “+” sign are connected to the terminal with the corresponding designation. Wires marked with a “-” symbol are connected via a relay. To connect the elements, it is recommended to use a two-core wire with a cross-sectional thickness of 0.5 mm.
The installation instructions included with the products always note that the operation of the lock is directly dependent on the voltage supplied to the relay. Before starting installation, to ensure high-quality operation of the product, it is recommended to purchase a closer device and a backup power source in the form of a UPS unit.

How the lock works
Most users have a question: how is an electromagnetic lock installed and operated? Inside there is a coil wound on a core. The rest of the space is filled with compound.
Depending on the voltage, the force of attraction in the electromagnetic lock changes. The higher it is, the stronger the plates are pressed. But do not put excessive voltage on the lock, this can lead to overheating of the coil. To prevent this phenomenon, it is necessary to install a current transformer.
In some individual cases, such devices can be repaired, but it all depends on the extent of the damage. Since the lock is hollow inside, removing the coil will not be difficult. The device can heat up for several reasons. Firstly, due to magnetization reversal of metal elements, and secondly, due to eddy currents.
To eliminate such problems, varnish insulation is installed on the electromagnetic deadbolt. As a result, no currents will arise, and the steel will not be magnetized so much. But still, installing varnish insulation will not completely eliminate the heating effect, so in addition to it, a capacitive capacitor is connected inside parallel to the coil. When the key is brought to the panel, the direction of the field changes and the currents die out. The tension in the electromagnetic lock immediately decreases and the door opens.
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.
Features of choice
First, you need to pay attention to the location of the housing, since it can be made for right- and left-sided gate leaves.
The main emphasis should be on the following points:
- level of reliability (for example, 2 rods can withstand much more mechanical load);
- compatibility with the entrance structure, since not all wickets or gates fit a certain leaf pattern;
- the electric lock can be connected both with and without an intercom;
- required functionality;
- different manufacturers may supply a battery for autonomous operation;
- possibility of opening mechanically;
- type of key for opening: electronic lock or remote control;
- locking mechanism: lever or cylinder.
Electromechanical latch
Installing an electric lock on a gate
Step-by-step connection of an electric lock:
- First you need to prepare the installation site. Then holes for fastening are cut out.
- After this, the product is secured to the gate with bolts or by welding. It should be taken into account that not any electric lock can be secured with a welding machine, since the products are often coated with a protective layer from external mechanical loads.
- Next, you should align the electric lock and check the compatibility of the latch with the counterpart in the support post.
- Then a hole is cut for the intercom. You need to make a branch from the electrical wire that is connected to the lock and connect it to the intercom.
- To be able to control the electric lock and intercom from home, cables from both mechanisms are installed next to the electrical wire. In the house they are connected to the control unit.
- If the locking design of the lock is compatible with the video intercom, then it must be connected directly to it, and then the wire must be pulled into the house.
