Easily add an automatic bed level system to your 3D printer with this inductive distance sensor. The sensor triggers on metal objects and has a theoretical measuring distance of
8mm. The diameter of the sensor is 18mm.
The sensor operates on 6V - 36V DC and is a PNP variant/NO. The sensor has an internal pull-up resistor which makes it necessary to add a series resistor to the signal connection.
Wire colours:
Brown: +V (12V)
Black: Output (to voltage divider)
Blue: 0V (gnd)
