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 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 table
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
[table 12
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.
