or teached switching point S
A
. Objects in the background, behind the user
set switching point, are ignored.

Accordingly for output 2 the switching point C (S

) is set.
• Foreground suppression FGS
Measured objects are detected as from the user set switching point S
A
up
to the maximum sensing distance. Objects in the foreground, between the
sensor’s blind zone and the user set switching point, are ignored.
