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-GF18-400NO-ZCA	NPN NO	3-wire	30-4000 mm
DK-GF18-400NC-ZCA	NPN NC	3-wire	30-4000 mm
DK-GF18-400PO-ZCA	PNP NO	3-wire	30-4000 mm
DK-GF18-400PC-ZCA	PNP NC	3-wire	30-4000 mm
DK-GF18-400NS-ZCA	NPN NO + NC	4-wire	30-4000 mm
DK-GF18-400PS-ZCA	PNP NO + NC	4-wire	30-4000 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.

Wiring

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.
