1 Alignment
WTL16P, WTS16P: Align sensor on 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
NOTE
For WTS16: If the objects are detected from above, we recommend installing the sensor at
an angle in order to prevent total reflection by a reflective surface,

2 Sensing range
WTLXX/WTSXX are photoelectric proximity sensors with background suppression. Depend‐
ing on the remission 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 main‐
tained.
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 correspond‐
ing diagram [see figure
sensing range and background [white 90%]). Remission: 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 [figure 2 1] as follows:
Example: x = 200 mm, y = 15 mm. That is, the background (white, 90%) is suppressed at a
distance of > 15 mm from the sensor.
