2 Mount the sensor and the reflector using suitable mounting brackets (see the SICK
range of accessories). Align the sensor and reflector with each other.
Note the sensor's maximum permissible tightening torque of 1.3 Nm Nm.
3 The sensors must be connected in a voltage-free state (U
in the graphics [B] must be observed, depending on the connection type:
– Male connector connection: pin assignment
– Cable: core color
Only apply voltage/switch on the power supply (U
tions have been established. The green LED indicator lights up on the sensor.
Explanations of the connection diagram (Graphic B):
Switching outputs Q and /Q (according to Graphic B):
WL23-2P/K (PNP: load -> M)
WL23-2N (NPN: load -> L+)
WL23-2S (relay output)
Q: light switching, object will not be detected, relay active
4 Align the sensor with a suitable reflector. Select the position so that the red emit‐
ted 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.
