Duet cant read input from sensor.

[StaticRed]

Hey so i got a inductive sensor which is working at 12v. It has 3 Cables, Plus GND and signal. When triggered on the signal line there is 12v, otherwise it is at 0v. When i now connected the probe to my duet 3 mini, for now only as a z endstop, it wil always read not stopped. Even if the sensor is stopped (it has a led to signal that). I put the signal line on io2.in. I read that it only detect when the pin is set to ground and not when a voltage is input. Is there any other connection i have to do then?

@staticred it sounds like a PNP output sensor. See https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_PNP_output_normally_open_inductive_or_capacitive_sensor.
