Electromechanical Locker Lock 12V DC with Strike Plate

This DFRobot electromechanical lock holds a locker or cabinet door with a hook that grips the supplied strike plate. A short pulse of 9 to 12 V DC unlocks it, and a spring then pushes the door open. A feedback contact reports whether the lock is open or closed. For emergencies, the lock has a mechanical emergency release.

Important: Only switch on the coil briefly, for 5 seconds at most; 1 second is enough. A longer switch-on time makes the coil hot and can damage it.
