INDUCTIVE PROXIMITY SENSOR DETECTION SWITCH

The Whadda inductive proximity sensor detection switch accurately detects metal objects that are within 4 mm of the sensor head. When a metal object is detected, the built-in red LED lights up and the black signal wire is internally shorted to ground through an NPN transistor. When no object is detected, the signal is floating/high impedance. Note: It is recommended to supply the sensor with no more than 6 V, and to put a series protection resistor between the signal output of the sensor and digital input of your board when connected to 5 V logic, such as Arduino® compatible boards.
