Omega’s new series of 2-wire DC inductive proximity sensors has a sensing distance range of 2 to 20 mm (0.08 to .79"). It comes in shielded and unshielded models with short barrel or standard lengths.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...
