Minimum distance in mm (y) between the set sensing
range and white background (90 % remission factor)
Example:
Safe suppression of the background
White background (90 %)
Black object (6 % remission factor)
Set sensing range x = 150 mm
Needed minimum distance to white
background y = 5.5 mm
Distance in mm (inch)
