Magnetic lock, which is mostly used in companies, schools, hospitals, enterprises and institutions, etc., guarantees people’s daily work and life, so a small magnetic lock can generate great power and firmly lock the door. Today, let’s learn about the "life experience" of magnetic locks.

　　Principle of electromagnetic lock

　　Magnetic lock is also called electromagnetic lock. Like electromagnet, its design is based on the principle of using current to generate magnetism. When the current passes through the silicon steel sheet of magnetic lock, the electromagnetic lock will generate strong suction force, and tightly absorb the adsorbed iron to achieve the effect of locking the door. The power supply used in the access control system belongs to weak current type. Generally, with a voltage of 12V and a very small current, a great magnetic attraction can be generated, and the access control system of the magnetic lock can be effectively controlled. By identifying whether the card swiper is legal or not, if it is legal, the power can be cut off, and the magnetic lock loses its attraction to open the door.

　　In fact, the magnetic lock does not have a very complicated mechanical structure, which plays a great role in the application of escape doors or fire exits, and is also a necessary security electronic product for fire exits. People who observe carefully will find that there is some black rubber on the surface of the magnetic lock. In fact, it uses epoxy resin as a protective lock body. These protective measures make the lock body safer and more reliable. This reliability is also manifested in the attraction of the magnetic lock. At present, the attraction is expressed in pounds (LB). Through static testing, the attraction of the magnetic lock can be calculated. Usually, a certain pulling force is applied to the magnetic lock and the lock plate. This pulling force is usually calculated in kg, that is, it is usually in the form of "how many kilograms of magnetic locks" in the market.

　　How to install the electromagnetic lock

　　Step 1: firstly, open the cover plate with a screwdriver, and then use a hexagon wrench to edge the plate to prepare for installation.

　　Step 2: Take out the installation cardboard, fold the cardboard along the dotted line, put the cardboard in the position to be locked as shown in Figure 2, then mark the place to be punched and punch it.

　　Step 3:

　　A. After fixing the iron plate, insert the hexagon socket head screw into the iron plate, place the rubber tile between two pieces of metal tiles, and then put it on the hexagon socket head screw. Insert the relay iron plate into the three holes punched in the door, insert the mushroom head from the other side of the door at the same time, and lock the relay iron plate on the door with a hexagon wrench.

　　B. Fixing the side plate Fix the side plate on the previously punched door frame (fixed in the long hole of the side plate) with two semicircular head screws. Note: Do not lock the side plate, so that it can move back and forth to facilitate the correction of the installation position.

　　C, correct the position of the side plate to make the position of the side plate and the relay iron plate suitable, so that the lock body can be in close contact with the relay iron plate.

　　D: After the lock body and the side plate are fixed, lock all countersunk screws, then remove the countersunk screws, and drill holes at appropriate positions for wiring. Finally, lock the lock body on the side plate with a hexagon wrench.
