The sensor is provided with a 2-twisted pair, shielded, 24 AWG, 35 pF/foot
capacitance cable. The wiring to the controller is as follows:
Shield Drain: Earth Ground
GRN: IN+
WHT: IN-
RED: +5 V
BLK: - 5 V
If the required cable length exceeds the 6 meters (20 feet) that is supplied,
wire the housing to a 190851 terminal box, then use a p/n 100084 cable to
reach the instrument. The maximum cable length is 30.5 meters (100 feet).
