Electronic 12V Lock (OT4873)

Perfect for lockers, drawers and small cabinets. The lock is water- and moisture-resistant, suitable for damp environments.

Wiring is simple: apply 12V DC to the red and black wires and the lock releases. A spring pushes the door slightly open—great for lockers.

Do not connect directly to an Arduino or other microcontroller. Drive it using a relay or MOSFET. Current draw: approx. 0.5A.

The blue and yellow wires are shorted when locked, allowing status monitoring.
