WTF12L/WTF12V are photoelectric proximity sensors with foreground suppression. The
photoelectric 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 WTF12L/WTF12V is
used to detect very flat objects on a conveyor belt.
Check the application conditions: Compare distance between sensor and background,
minimal object height as well as remission capability of background and object with the
associated diagram (see figure 8, page
height). Remission factor: 6% = black 1, 90% = white 2 (referring to standard white as
per DIN 5033).
