2 Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
Note the sensor's maximum permissible tightening torque of 1.3 Nm.
Note the preferred direction of the object relative to the sensor [see A].
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
Technical data and connection diagrams (figure B) starting on page 69.
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):
WT(F)18-3P/K/V (PNP: load -> M)
WT(F)18-3N (NPN: load -> L+)
Alarm/health = diagnostic output (see Additional functions)
4 WT18-3Xx3x / -3Xx8x: Align the sensor with the object. Select the position so that
the red emitted light beam hits the center of the object. You must ensure that the
optical opening (front screen) of the sensor is completely clear [E]. We recommend
making the adjustments using an object with a low remission.
WT18-3Xx1x / -3Xx7x: Align the sensor with the object. Select the position so that
the infrared light (not visible) hits the center of the object. The correct alignment
can only be detected via the LED indicators. Please refer to Graphics C and E. You
must ensure that the optical opening (front screen) of the sensor is completely
clear. We recommend making the adjustments using an object with a low remissi‐
on.
