Example: Reliable suppression of background:
White background (90% remission)
Black object (6% remission)
Set sensing range x = 150 mm
Required minimum distance to white background y = 20 mm
Sensing range on black, 6% remission

see table 2, page 9. If the switching output fails to
9, check the application conditions.
