LM-3502/LM-3505 Electromagnetic Lock with Holding Force 280kg (LM Series)
Electromagnetic lock with holding force 280kg, with door sensor (model LM-3505). Features: input voltage DC12V; working current 400mA±5 % (LM-3502) / 420mA±5 % (LM-3505); tensile force range 280kg±5 %; lock body size 250x47x25.5mm; iron plate size 158x43x11mm; signal output (only LM-3505): NO/COM/NC.
Electromagnetic locks apply the principle of electromagnetism. When the electric current passes through the silicon steel sheet, the electromagnetic lock will produce a strong suction force to tightly attract the iron plate to lock the door. A small electric current will produce a great magnetic force. When users turn off the power of the electromagnetic lock, it will lose its suction, so that users can open the door.
