Smallest Door/Window Sensor

I’ve been looking through the forum for a very small sensor to put in a cabinet. Does anyone have any suggestions. Everything I can find on here is just too big.


Try these - they’re very slim and regularly available at a good price on If the layout of the cabinet allows, you might be able to mount the sensor under the top of the opening and put the smaller magnet component on the door; you could remove the magnet from its casing as well if you’re looking to go really small, but you’d still need a way to mount it.

Great! thanks. I’ll try them.

Even smaller

Thanks. Saw those but a little more than I want to spend for this project
