SICK WTL16, Operating Instructions Manual

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 figure 2 ] (x = sensing range, y = minimum distance between set
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 [
see 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 of the configured sensing range.
