This 12V electromagnetic lock is a great choice for various applications. It comes with two control wires (red for positive and black for negative). Simply power it on or off to unlock or lock. We've treated the metal surface of the shell and frame with electroless nickel plating, making it highly durable and resistant to corrosion. The bolt and lock hole are crafted from pure copper, ensuring a smooth operation without getting stuck. You can rotate the bolt to 90, 180, or 270 degrees to fit any door. When the copper - wire coil inside the lock is energized, the bolt quickly pulls into the coil's center. It has excellent heat resistance and a long service life. Use it with relay modules and micro - controllers for a smart home setup. It's also perfect for locking sales machines, storage racks, file cabinets, and automated equipment.

Using this electromagnetic lock is easy. First, connect the red wire to the positive terminal and the black wire to the negative terminal. To unlock the lock, power it on. To lock it, power it off. You can rotate the bolt to 90, 180, or 270 degrees to fit different doors before installation. When using it for a smart home, connect it with relay modules and micro - controllers. For other applications like sales machines or storage racks, just install it in the appropriate place. Keep in mind that the operating voltage is 12V, so use a suitable power source. Don't exceed the recommended operating current of 0.4A. For maintenance, periodically check the connections of the wires to make sure they are secure. Wipe the nickel - plated shell with a soft, dry cloth to keep it clean. The pure - copper parts are durable, but avoid using sharp objects to scratch them.
