WTS16 MultiPulse 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 background is to be maintained.
Check the application conditions:
Adjust the sensing range and distance to the object and background as well as the
remission capability of the object according to the corresponding diagram (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 (relative to standard
white as per DIN 5033). We recommend that the adjustment be performed with an
object with low remission factor.
The minimum distance (= y) for the background suppression can be determined from
the diagram [ figure 12 1] as follows:
Example: x = 400 mm, y = 80 mm. That is, the background (white, 90%) is suppressed
at a distance of > 80 mm of the configured sensing range.
