Application Example
Simple Detection of Glossy, Uneven Objects
BGS (Background Suppression)
Selectable by
Changing Cable
Connection
FGS (Foreground Suppression)
Objects beyond the set
distance, such as the
conveyor, will not be
detected. The hysteresis is
10% or less, so at a set
distance of 40 mm, steps
with a thickness of 4 mm
can be detected on objects.

Glossy, uneven objects are
reliably detected because
the OFF (incident) status
occurs only when the
conveyor is detected, and
ON (interrupted) status
occurs only when an object
exists or when reflected light
is not returned to the
Sensor. (Depending on the
shape of the object, an OFF-
delay timer may be
required.)
