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

【Electronic Lock with Deadbolt】It consists of two elements: the "fixed" black lacquered part and the metal hook. You need to slam the door to close it and apply 12V to the cables to unlock it. The electromagnetic lock is mainly made of carbon steel, and the lock hook can withstand a tensile force of 150kg. 【Connection Precautions】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 digital code, everything will turn off when unlocking. Since the power supply is not powerful enough, you will need to power the coil separately or use a special power supply for the lock. 【Opened via Intercom】The lock can be opened via intercom with a little DIY effort. All you need to do is send a 12V 2A pulse. Therefore, provide a small relay with a 12V 3A power supply in case of a power outage. Perfect for securing cabinets to prevent children from accessing them. 【Energy Saving and Long Service Life】Shock, puncture, and theft protection.
