The design of the magnetic lock (or electromagnetic lock) is the same as the electromagnetic principle as the electromagnetic magnet. When the current passes through the silicon steel sheet, the electromagnetic lock will produce a strong suction.Essence
Electromagnetic lock principle
The principle of electromagnetic magnetism is used. When the current passes through the silicon steel sheet, the electromagnetic lock will produce a powerful suction force tightly to suck the absorbing iron plate to achieve the effect of locking the door.Very small currents will also make the electromagnetic lock produce a great magnetic force. The access control system identification personnel of the electromagnetic lock power supply effectively control the power disconnection after the electromagnetic lock power supply.Because the electromagnetic lock does not have a complex mechanical structure and the structure of the lock tongue, it is suitable for the path control of the escape door or the fire door.It is used to protect the lock with an internal epoxy tree.At present, the inhalation strength of the electromagnetic lock is expressed by LB (pounds), and the test method is static pressure.The so -called static pressure is to gradually increase the tension of the adsorption iron plate after the electromagnetic lock is powered on. When the inhalation power beyond the electromagnetic lock, the adsorption iron plate is instantly opened.In addition, the force of electromagnetic locks and adsorption iron plates must be face -to -face and is a straight pressure. So as the most of the electromagnetic locks are the largest.The adsorption iron plate may be briefly magnetized due to the magnetic induction of the electromagnet for a long time.
Electromagnetic lock installation
I. Magnetic locks can be installed horizontally or vertically on the door frame, but the magnetic lock requires an angle regardless of the horizontal or vertical installation of the door frame.Second, when the magnetic lock is installed and adsorbed, it is best to be exposed or entered.Third, the magnetic lock is installed indoors, because exposed to the outside is safe! And it is best to hide it in the door frame when installation.
