6.3 Check the application conditions
WTx10 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.
WTM10 with functional principle BGS
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%) :
•
10 mm, at a distance of 500 mm (Mode 3 - Precision), Long Range
•
10 mm, at a distance of 300 mm (Mode 3 - Precision), Short Range
NOTE
Smallest detectable object (MDO) typ.:
•
0.6 mm, at a distance of 250 mm, Long Range
•
0.2 mm, at a distance of 150 mm, Short Range
