In our life and work, it is not difficult to find that holding a card or buckle in our hand can help us safely open the door. In fact, in the access control system, there is an electronic lock that is widely used-a automatic magnetic lock. Mainly used in various types of companies, schools, hospitals, units and enterprises, magnetic locks protect people's daily work and life, so a small magnetic lock can generate great power and lock the door firmly.
A magnetic lock is also called an electromagnetic lock. Its design is the same as an electromagnet. It uses the principle of generating magnetism by current. When the current passes through the silicon steel sheet of the magnetic lock, the electromagnetic lock will generate a strong suction force, which will firmly attract the adsorption iron to achieve the lock. The effect of the door. The power supply used in the access control system is of the weak current type. Generally, a large magnetic attraction can be generated through a voltage of 12V and a very small current, which can effectively control the access control system of the magnetic lock. By identifying whether the person who swipes the card is legal, If it is legal, the power can be cut off, and the magnetic lock will lose its suction and open the door.
In fact, the magnetic lock does not have a very complicated mechanical structure. It plays a great role in the use of escape doors or fire passages. It is also a must-safe electronic product for fire passages. Those who observe carefully will find that the magnetic lock has some black rubber on its surface. In fact, it uses epoxy resin to protect the lock body. These protective measures make the lock body safer and more reliable. And this reliability is also reflected in the magnetic lock’s suction power. At present, the suction power is expressed in pounds (LB). Through the static test method, the magnetic lock’s suction force 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, which is the nominal form of "how many kg of magnetic locks" on the market.
Advantages of magnetic lock: Because of its feature that it can be opened when the power is off, it is usually used in escape installations. It is also a necessary lock system for consumer channels. It only needs a very low current to run, which not only saves electricity well, but also contributes to green energy conservation and environmental protection.
Magnetic locks for public security are widely used in important buildings and become an important link that cannot be ignored in the management of high-tech access control systems. It can not only operate reliably, but also achieve the characteristics of anti-theft, providing an important guarantee for security.
