Mounting Direction for Distance-settable Models
•
Make sure that the sensing side of
the Sensor is parallel with the
surface of the sensing objects.
Normally, do not incline the
Sensor towards the sensing
object.
If the sensing object has a glossy
surface, however, incline the Sensor
by 5
°
to 10
°
as shown in the
illustration, provided that the Sensor
is not influenced by background
objects.
•
If there is a mirror-like object below the Sensor, the Sensor may not
operate stably. Therefore, incline the Sensor or separate the
Sensor from the mirror-like object as shown below.
•
Do not install the Sensor in the wrong direction. Refer to the
following illustration.
Install the Sensor as shown in the following illustration if each sensing
object greatly differs in color or material.
•
The stability indicator may turn off in reaction to reflection from
background objects. In such cases, incline the Sensor by 10
°
as
shown in the illustration for more stable detection.

Indicator Operation
Note: If the stability indicator is lit, the detection/no detection status is
stable within the rated ambient operating temperature (
−
10 to
55
°
C).
