WTM4S are photoelectric proximity sensors with background and foreground suppres‐
sion. 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.
Background suppression: MultiMode 1, 3, 4, 5, 6
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 making the adjustments using an object with a
low remission factor.
Minimum distance between set sensing range and background (black 6% / white
90%) :
•
5 mm, at 150 mm distance (MultiMode 1, 3, 4, 5)
•
8 mm, at 250 mm distance (MultiMode 1 + 6)
MultiMode 1, 3, 4, 5:
