HAMMER PADLOCK

Electromagnetic lock

Magnetic lock (or electromagnetic lock) design and the same as the electromagnet, is the use of the principle of electromagnetism, when the current through the silicon steel, the electromagnetic lock will produce a strong suction tightly sucked iron plate to achieve the effect of locking the door The As long as a small current electromagnetic lock will produce a great magnetic force, control the electromagnetic lock power access control system to identify the right after the power, the electromagnetic lock to lose suction to open the door. Because the electromagnetic lock is not complicated mechanical structure and the structure of the tongue, apply to the escape door or fire door access control. Its internal use of perfusion epoxy resin protection lock body.
application
Electromagnetic locks are mainly used for indoor high-voltage switchgear front and rear doors need to lock the site to achieve interlock, to prevent the occurrence of misuse, power generation and power supply departments indispensable locking device. In addition, in order to meet the needs of integrated automation substation, some electromagnetic locks also increased the lock auxiliary contacts, in the lock of the sub-location to provide users with a pair of corresponding switch contacts, user-friendly interlocking and integrated automation sampling, to avoid It is an ideal locking device for modern substation equipment.
