Foreground suppression (VGA): MultiMode 2
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, the FGS mode is used
to detect very flat objects on a conveyor belt.
