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 0.6 Nm.
3 The sensors must be connected in a voltage-free state (V
in the graphics [B] must be observed, depending on the type of connection:
– Male connector connection: pin assignment
– Cable: core color

Explanations of the connection diagram (graphic B):
Switching outputs Q and /Q (according to graphic B):
WL9(M4)(G)-3P (PNP: load -> M)
WL9(M4)(G)-3N (NPN: load -> L+)

Alarm / Health= alarm output (see Additional functions)
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.
