What are the differences between electric mortise locks and magnetic locks?
As the security requirements for electric locks for access control are getting higher and higher, various types of electric locks have also sprung up. The most common ones are electric bolt locks and magnetic locks, because the two electric locks can provide excellent performance when they cooperate with the access control system.
However, there are still differences between them. Electric bolt locks are often used on various flat-opening glass doors for access control (two-way opening). At the same time, their concealed installation features are more beautiful and suitable for places with high confidentiality requirements.
There are two types of electric bolt locks now, power-on unlocking type and power-off unlocking type. When the power is off, the lock tongue of the power-on unlocking type electric bolt lock is in an extended state, while the lock tongue of the power-off unlocking type electric bolt lock is extended when the power is off. In large shopping malls and office buildings where people are crowded, in order to meet fire protection requirements, power-off electric locks are generally used to prevent the door from opening automatically in emergencies such as fire.
Magnetic lock (double door magnetic lock), also known as suction lock, generates magnetic force in the lock body after power is turned on. Any iron object approaching will not be attracted. The larger the force area of the iron object, the more sufficient the suction force generated, that is, it is not easy to swing. Magnetic force itself is a force, so the force also has a size, so the magnetic lock also has force constraints in the setting, 180kg, 280kg, 380kg, etc. Under the force constraint, as long as we manually add force, the lock can be opened beyond the force of its own constraint.
The design of the magnetic lock is the same as that of the electromagnet, which uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the magnetic lock will generate a strong magnetic attraction to tightly adsorb the iron plate to achieve the effect of locking the door. And to achieve this effect, only a small current is needed to make it generate such a large suction force. When the personnel swipe the card to verify correctly, the controller performs the power-off operation, and the magnetic lock (double door magnetic lock) loses the magnetic attraction and can open the door. Because magnetic locks do not have complicated mechanical mechanisms, they are particularly suitable for access control of escape passages.
The difference between magnetic locks and electric bolt locks is that:
1. Electric bolt locks are not restricted by force and do not have the defect of passive opening; magnetic locks are restricted by magnetic force. When the load of the lock body itself is exceeded, the lock can be opened, which is the defect of magnetic locks.
2. Electric bolt locks are more flexible in use than magnetic locks. Electric bolt locks can be opened in both directions without restriction. However, magnetic locks (double-door magnetic locks) can only be opened in one direction and are restricted by the installation position. With the widespread application of access control systems in various buildings, electric locks, as an important part of access control systems, are becoming more and more popular in the market, which has also promoted the more intelligent development of electric locks.
