phics [B] must be observed, depending on the type of connection:
– Male connector connection: pin assignment
– Cable: core color

Switching outputs Q and /Q (according to Graphic B):
GRL18-P (PNP: load -> M)
GRL18-N (NPN: load -> L+)
4 Align the sensor with a suitable reflector. Select the position so that the red emitted light
beam hits the center of the reflector. The sensor must have a clear view of the reflector, with
no object in the path of the beam [see E]. You must ensure that the optical openings of the
sensor and reflector are completely clear.

5 Sensor with potentiometer:
The sensitivity is adjusted with the potentiometer (type: 270°). Clockwise rotation: operating
reserve increased; counterclockwise rotation: operating reserve reduced. We recommend
setting the potentiometer to "Maximum." A lower operating reserve may be necessary for
depolarizing surfaces.
The sensor is adjusted and ready for operation. Refer to Graphics C and G to check the func‐
tion. If the switching output fails to behave in accordance with Graphic C, check application
conditions. See section Fault diagnosis.
