Electric Solenoid Lock (9V~12V)

The Electric Solenoid Lock (9V~12V) is a robust electronic latch mechanism engineered with a steel housing and a temperature-tolerant copper coil. Equipped with built-in signal feedback to monitor the latch state, it is well suited for makers, students, and developers building IoT smart lockers, access control enclosures, and automated storage systems.

Durable steel construction

The assembly features a steel-made casing, steel casting components, and a robust latch hook designed for a service life exceeding 500,000 cycles. It provides dependable physical security for DIY lockers, drawers, and cabinet doors.

Pure copper electromagnetic coil

A pure copper electromagnetic coil provides stable actuation and temperature tolerance. Supplying an external 9V to 12V DC power source energises the coil to quickly retract the lock bolt.

Integrated lock state feedback

The unit includes a signal feedback line that allows your microcontroller or control board to verify the current open or closed state of the lock. This enables easy integration into smart home systems, interactive installations, and IoT setups.

Connection and actuation timing

The lock operates at 9V to 12V DC with a working current of 1.5A. To prevent coil damage from overheating, each unlock pulse should be kept strictly under 5 seconds.

Dimensions and package contents

Measuring 73 x 58 x 13.3 mm, this compact mechanism fits neatly into space-constrained enclosures. Each package includes one solenoid lock, a matching latch, and a Gravity connector cable.
