How does a magnetic lock work?

In our life and work, it is not difficult to find that holding a card or buckle in our hand can help us open the door safely. In fact, in the access control system, there is an electronic lock that is widely used - magnetic lock, which 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. So many people will have questions, how does the magnetic lock work? Is it just electric current to drive the electromagnet? With these questions, Ascendant will introduce this magical "it".

Magnetic lock is also called electromagnetic lock. Its design is the same as that of electromagnet. It uses the principle of current to generate magnetism. When the current passes through the silicon steel sheet of the magnetic lock, the electromagnetic lock will generate a strong suction force, which tightly attracts the adsorption iron to reach the lock. door effect. The power supply used in the access control system belongs to the weak current type. Generally, a voltage of 12V and a very small current can generate a large magnetic attraction, which can effectively control the access control system of the magnetic lock. By identifying whether the card swipe is legal, If it is legal to power off, the magnetic lock loses suction to open the door.

In fact, the magnetic lock does not have a very complicated mechanical structure. It plays a great role in the application of escape doors or fire escapes, and is also a must-have security electronic product for fire escapes. 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 more secure and reliable. And this reliability is also reflected in the suction force of the magnetic lock. At present, the suction force is expressed in pounds (LB). Through the static test method, the suction force 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, the market is usually in the nominal form of "how many kg magnetic locks".

Advantages of magnetic locks: Because of its ability to open immediately after power failure, it is usually used in escape installations, and it is also a must-have lock system for consumer channels. It only needs a very low current to operate, which not only saves electricity very well, but also contributes to green energy saving and environmental protection.

Magnetic locks for public security are widely used in important buildings and become an important link 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.

磁力锁的工作原理是什么？

在我们生活、工作中其实不难发现，手里拿着一张卡片或者卡扣，它就可以帮我们安全打开门，其实在门禁系统中，有一个电子锁具应用很广泛——磁力锁，它主要应用在各种类型的公司，学校、医院、单位企事业，磁力锁保障着人们的日常工作与生活，那么小小的磁力锁竟能产生莫大的力量并且牢牢锁住门。那么很多人会有疑问，磁力锁的工作原理是怎么来着呢？单单只是靠电流驱动电磁吗？带着这些疑问，Ascendant来介绍一下这个神奇的“它”。

磁力锁也叫电磁锁，它的设计与电磁铁一样，是利用电流产生磁的原理，当电流通过磁力锁的硅钢片时，电磁锁会产生强大的吸力，紧紧地吸住吸附铁达到锁门的效果。而门禁系统中所使用的电源都是属于弱电型，一般通过12V的电压以及非常小的电流，就可以产生很大的磁吸力，有效的控制磁力锁的门禁系统，通过识别刷卡人员是否合法，如果合法即可断电，磁力锁失去吸力开门。

其实磁力锁并没有非常复杂的机械结构，在应用于逃生门或者消防通道中起到很大的作用，也是消防通道的一个必须安防电子产品。如何细心观察的人会发现，磁力锁其表面有一些黑色的橡胶，其实它是用管住环氧树胶作为保护锁体的，通过这些保护措施让锁体更加安全可靠。而这种可靠还表现在磁力锁的吸力，目前吸力以磅（LB）表示，通过静态测试的方法，可以算出磁力锁的吸力，通常对磁力锁以及锁板施加一定的拉力，这个拉力通常是以kg来计算，也就是市面上通常以“多少kg磁力锁”来进行标称的形式。

磁力锁的优点：由于其能在断电即开的特点，通常被应用于逃生方面的安装，它也是消费通道的必备锁具系统中。其只需很低的电流就可运行，既能很好的省电，有助于绿色节能环保。

用于公共安全防范的磁力锁广泛应用于重要建筑中，成为高科技门禁系统管理中不可忽视重要环节，它不仅能可靠运行，也能达到防盗的特点，为安防做出提供重要保障。
