12V dc Fail-Safe Cabinet Drawer Lock Magnetic Solenoid for Door Access Control System (with Sensor Switch)

【Electronic lock with the bolt】There are 2 elements, the fixed part painted black and the metal hook. We have to slam the door to close it and put 12v on the wires to unlock it. The electromagnet lock is mainly carbon steel material, the lock hook can bear the pull of 150kg. 【Precautions when plugging in】The lock should not be powered for more than 3 seconds and the voltage should be 12V 2A. If you use a relay with a digicode and when you unlock, everything goes out. Because the power supply is not powerful enough, you have to supply the coil separately or put a dedicated power supply for the lock. 【Open via intercom】The lock can be opened via intercom with a little DIY. You just have to send a 12v and 2 amp pulse, so provide a small relay in case of lack of power with a 12v 3 amp power supply. Perfect for securing closets, so children can't get in. 【Energy Saving & Long Life】Shockproof, puncture proof and anti-theft protection. Mechanical life, when designing the load condition,
