Review: Prox switch - Works well interfacing with an Arduino. No debouncing necessary either. I've purchased many of these in both 24 volt and 5 volt and they all work perfectly.
Review: Work as expected NPN NO sensors - These work as expected, proper wiring is required. Blue wire to Ground ( - ), Brown wire to VCC ( + ), Black wire to load. For NPN sensor connect load between VCC ( + ) and Black wire. Simple. Anyway they provided the diagrams.

### ⭐⭐⭐⭐⭐ Prox switch
*by R***. on November 17, 2025*

Works well interfacing with an Arduino. No debouncing necessary either. I've purchased many of these in both 24 volt and 5 volt and they all work perfectly.

### ⭐⭐⭐⭐⭐ Work as expected NPN NO sensors
*by M***K on October 25, 2022*

These work as expected, proper wiring is required. Blue wire to Ground ( - ), Brown wire to VCC ( + ), Black wire to load. For NPN sensor connect load between VCC ( + ) and Black wire. Simple. Anyway they provided the diagrams.

### ⭐⭐⭐⭐ Works well, using it to detect non-ferrous metals
*by A***K on September 15, 2024*

You need to know how to wire up a proximity sensor. The three wire one makes it easy as you don't have to do it in-line. Watch some videos as to how it is done. I'm able to detect copper and brass pretty easily within the specs of the part.
