How does an electromagnetic lock (magnetic lock) work?
In our daily life and work, it is not difficult to find that holding a card or buckle in hand can help us open the door safely. In fact, in the access control system, there is an electronic lock that is widely used - electromagnetic lock. It is mainly used in various types of companies, schools, hospitals, units and enterprises. Electromagnetic locks protect people's daily work and life. So a small electromagnetic lock can generate great power and lock the door tightly. So many people will have questions, what is the working principle of electromagnetic locks? Is it just driven by current? With these questions, the editor will introduce this strange "it"
Magnetic locks are also called electromagnetic locks. Its design is the same as that of electromagnets. It uses the principle of current generating magnetism. When the current passes through the silicon steel sheet of the magnetic lock, the electromagnetic lock will generate a strong suction force, tightly sucking the adsorption iron to achieve the effect of locking the door. The power supply used in the access control system is weak current type. Generally, a 12V voltage and a very small current can generate a large magnetic attraction, which is effective in controlling the access control system of the magnetic lock. By identifying whether the card swipe person is legal, if it is legal, the power can be cut off, and the magnetic lock loses the attraction to open the door.
In fact, the electromagnetic lock does not have a very complex mechanical structure. It plays a big role in the use of escape doors or fire passages. It is also a necessary security electronic product for fire passages. If you observe carefully, you will find that there is some black rubber on the surface of the magnetic lock. In fact, it is used to protect the lock body with epoxy glue. These protective measures make the lock body safer and more reliable. And this reliability is also reflected in the suction of the magnetic lock. The suction is now expressed in pounds (LB). Through the static test method, the suction of the magnetic lock can be calculated. Generally, a certain pulling force is applied to the magnetic lock and the lock plate. This pulling force is generally calculated in kg, which is the way to use "how many kg magnetic locks" on the market.
Advantages of electromagnetic locks: Because of its ability to open when power is off, it is generally used in escape installations, and it is also a necessary lock system for consumption channels. It only requires a very low current to work, which can not only save electricity well, but also contribute to green energy conservation and environmental protection.
Magnetic locks used for public safety prevention are widely used in important buildings and have become an important link that cannot be ignored in the management of high-tech access control systems. It can not only work reliably, but also achieve anti-theft characteristics, providing important guarantees for security.
