WTF9-3 are photoelectric proximity sensors with foreground suppression. The photo‐
electric proximity sensor requires a background as a reference. The remission factor
and position of the background should remain as uniform as possible. The maximum
distance (x) between the photoelectric proximity sensor and background as well as the
minimum object height (y) must be upheld. As a rule, a WTF9-3 is used to detect very
flat objects on a conveyor belt.
Check the application conditions: Compare distance between sensor and background
as well as remission capability of background and object with the associated diagram
(see figure 6, page
24) (x = sensing range, y = minimum object height). Remission
factor: 6% = black 1, 90% = white 2 (referring to standard white as per DIN 5033).
