The minimum distance (= y) for background suppression can be determined from
diagram [H] as follows:
Example: x = 120 mm, y = 7 => 7 % of 120 mm = 8.4 mm. That is, the background
is suppressed at a distance of > 128.4mm from the sensor.

Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
Note the sensor's maximum permissible tightening torque of 0.8 Nm.
Note the preferred direction of the object relative to the sensor [see A].

The sensors must be connected in a voltage-free state (V
S
= 0 V). The information
in the graphics [B] must be observed, depending on the type of connection:
–
Male connector connection: pin assignment
–
Cable: core color
Image: B
Only apply voltage/switch on the power supply (V
S
> 0 V) once all electrical connec‐
tions have been completed. The green LED indicator lights up on the sensor.

Switching outputs Q and /Q (according to Graphic B):
WTB4S-3Exxxx and WTB4S-3Fxxxx
D: dark-switching, output (Q) switches off when an object is present in the sensing
range.
WTB4S-3P1332 and WTB4S-3Px1xx
WTB4S-3N1332 and WTB4S-3Nx1xx
L: light switching, output (Q) switches when an object is present in the sensing ran‐
ge.
WTB4S-3P1131 and WTB4S-3N1131
WTB4S-3Px231 and WTB4S-3Nx231

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 adjust‐
ments using an object with a low remission.
