1 Alignment
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 sen‐
sor is completely clear [figure
NOTE
For WTS26P: 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
WTS26 are photoelectric proximity sensors with background suppression. Depending on
the remission of the object to be detected, and perhaps the background behind it, a mini‐
mum 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 [figure 2, 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 = 500 mm, y = 25 mm. That is, the background (black, 6%) is suppressed at a
distance of > 25 mm from the sensor.
