Magnetic lock design and an electro magnet, is to use electricity magnetic principle, when a current is passed through the silicon steel sheet, the electro magnetic lock can have a strong suction tightly sucked to lock the door effect adsorption of iron. As long as the little current electro magnetic lock can produce great force, the electro magnetic lock controlling power control system identification correctly after power failure, the electro magnetic lock lose suction can open the door. Because the magnetic lock without complicated mechanical structure and the lock tongue structure, applicable in the escape door and fire door access control. Its internal perfusion epoxy resin protective lock.
