WTS26 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 back‐
ground 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 table
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
[table 13
1] as follows:
Example: x = 500 mm, y = 25 mm. That is, the background (white, 90%) is suppressed
at a distance of > 25 mm of the configured sensing range.
