Sensing range
WTB4FP MultiSwitch 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 back‐
ground should be maintained.
Check the application conditions:
Adjust the sensing range and distance to the object or background as well as the
radiance capability of the object according to the corresponding diagram (x = sensing
range, y = minimum distance between set sensing range and background [white, 90%])
Radiance 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 as follows:
Example: x = 100 mm, y = 4 mm. That is, the background (white, 90%) is suppressed at
a distance of > 4 mm from the sensor.
