Adafruit Small Lock-style Solenoid 12VDC 350mAh 2-pin JST

Compact 12 V solenoid lock for cabinets

This small lock-style solenoid pulls its slanted slug into the coil when 9–12 VDC is applied, allowing a door or drawer to open. It draws roughly 350 mA at 12 V and requires no power to stay locked. The four-hole mounting bracket makes it straightforward to secure inside a basic cabinet or safe. Hobbyists and engineers building custom access-control projects will find it easy to integrate.

Thermals noise and power draw

In normal operation the coil warms modestly while energised and returns to ambient temperature when power is removed. There are no moving fans, so the device runs silently apart from a faint mechanical click when the slug engages. Current draw stays near the rated 350 mA at 12 V, so a modest DC supply or battery pack is sufficient for intermittent use.

Slanted slug and fixed orientation

The slug features a slant cut that cannot be reversed, so the lock only works in one mounting direction. The included four-hole bracket provides rigid alignment but offers no adjustment for latch depth. No driver board, relay or control software is supplied; the builder must add switching circuitry and any access logic required for the project.
