This is a simple to use inductive sensor. Bring the blue end of the sensor within 4mm of an inductive surface (ie metal surface) and the output goes low and the internal LED indicator turns on.
Specs:
- Sensor range: Triggers at 4mm
- Cable length: 45"
- NPN
Wiring:- Brown: 6 to 36v DC
- Black: Output - (0 volts when triggered (sensing) or near Brown wire voltage when not)
- Blue: GND
