● When measuring in narrow locations or inside holes, mount the prod-
uct so that optical path from the light emitting part to light-receiving
part is not interrupted.
● Mount the sensor to a wall as follows, so that the multiple light reec-
tions on the wall do not reach the light-receiving part. When the reec-
tion factor on the wall is high, it is effective to use a dull black color.

1. Press the TEACH key when the back-
ground is present.
2. Press the TEACH key when the sensing
object is present.
Stable sensing is possible.
Stable sensing is not possible.
Limit teaching
This teaching method is recommended, if small objects or objects in the
background exist.

2. When an object in the background is used
as reference, press the UP key to set the
threshold on the sensor side.
When a sensing object is used as a refer-
ence, press the DOWN key to set the
threshold on the sensing object side.
3. Teaching is completed.
