WTS26P: 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 WTS26P: 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,

Sensing range
Check the application conditions: Adjust the sensing range and distance to the object
or background and the remission capability of the object according to the correspond‐
ing diagram [sfigure 4 and
set 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 mak‐
ing the adjustments using an object with a low remission.
The minimum distance (= y) for background suppression can be determined from dia‐
gram [figure 4 1] as follows:
Example: x = 500 mm, y = 25 mm. That is, the background (black, 6%) is suppressed at
a distance of > 25 mm from the sensor.
