Hi,
You need to supply switched 12V+ to the + pin on the sensor, and then from the - pin on the sensor you wire this to a UDig input, with a bridge through a 220 Ohm resistor to 0V.
This should give you a signal range between 1.6V and 3.6V, so use a Threshold of 2.5V and a Hysteresis value of 0.2V.
