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
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,

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.
Check the application conditions: Adjust the sensing range and distance to the object
or background as well as the remission capability of the object according to the corre‐
sponding diagram
[see figure
sensing range and background (white 90%)). Remission factor: 6% = black 1, 18% =
gray 2, 90% = white 3 (referring to standard white as per DIN 5033). We recommend
that the adjustment be performed with an object of low remission.
The minimum distance (= y) for the background suppression can be determined from
the diagram
[see figure 3
1] as follows:
Example: x = 200 mm, y = 15 mm. That is, the background (white, 90%) is suppressed
at a distance of > 15 mm of the configured sensing range.
