7.1 Alignment
WTL16, WTS16: Align the sensor with the object. Select the position so that the red
emitted light beam hits the center of the object. It is important to ensure that the
optical opening (front screen) of the sensor is completely clear [
see table ].
NOTE
For WTS16: If the objects are detected from above, we recommend installing the sen‐
sor at an angle in order to prevent total reflection by a reflective surface,
see figure 13 -
figure 16 .

7.2 Check the application conditions
WTL16, WTS16 are photoelectric proximity sensors with background suppression.
Depending on the remission factor of the object to be detected, and perhaps the
background behind it, a minimum distance (y) between the set sensing range (x) and
the background is to be maintained.
