Orderable models in this group

This group contains 6 orderable part number(s). Choose the output type and sensing distance you need, then quote the exact part number from the table below.

Part number Output Wires Sensing distance
DK-GF18-1500NO-ZBA NPN NO 3-wire 15000 mm
DK-GF18-1500NC-ZBA NPN NC 3-wire 15000 mm
DK-GF18-1500PO-ZBA PNP NO 3-wire 15000 mm
DK-GF18-1500PC-ZBA PNP NC 3-wire 15000 mm
DK-GF18-1500NS-ZBA NPN NO + NC 4-wire 15000 mm
DK-GF18-1500PS-ZBA PNP NO + NC 4-wire 15000 mm

Output codes: NO / NC / NS = NPN NO / NC / NO+NC; PO / PC / PS = PNP NO / NC / NO+NC; J = relay output. 3-wire models use one switched output, 4-wire models provide NO + NC, and relay models provide NO + NC contacts.

All six DC 3-wire / 4-wire NPN and PNP NO, NC and NO+NC connections used by this group.
Wire colour Function
Brown (1) +10-30 V DC
Blue (3) 0 V
Black (2 / 4) Switched output to load
White (2) Second switched output on 4-wire models

Confirm the wiring against the label of the unit received before energising. Do not connect the output to a load exceeding the rated current.
