Mounting method
1. Hook the upper protruding
portions of the Slit to the up-
per indented mounting por-
tion of the Sensor and
adjust the position of the
Slit so that the Slit will be
parallel to the lens surface.
2. Press the lower protruding
portion of the Slit onto the
indented mounting portion
of the Sensor until the Slit
snaps in.
Mounting condition
Demounting method
1. Press the upper portion of
the Slit.
2. Disconnect the lower pro-
truding portion of the Slit
from the Sensor and re-
move the Slit.

Simple Detection of Glossy, Uneven Objects
BGS
(Background Suppression)
Objects beyond the set distan-
ce, such as the conveyor, will
not be detected. The hystere-
sis is 10% or less, so at a set
distance of 40 mm, steps with
a thickness of 4 mm can be de-
tected on objects.
Selectable by Changing Cable Connection

OFF (interrupted)

(for Light-ON setting)
FGS
(Foreground Suppression)
Glossy, uneven objects are re-
liably detected because the
OFF (incident) status occurs
only when the conveyor is de-
tected, and ON (interrupted)
status occurs only when an ob-
ject exists or when reflected
light is not returned to the Sen-
sor. (Depending on the shape
of the object, an OFF-delay
timer may be required.)
