Maximum Sensitivity Setting
• Use Through-beam Fibers for detection of opaque objects.
• Use the Diffuse Fibers for detection of objects with fixed background.
The threshold should be set to a level slightly higher than the Zero point when detecting objects that completely interrupt light.
Diffuse Sensor
The number of incident level indicators that are lit will depend on the location of the object. The bottom indicator of the threshold indicators
will always be lit.

• Ideal for the detection of object surface irregularities or minute objects.
• Ideal for the detection of objects against a background that reflects light irregularly.

Diffuse Sensor
1. Press the SET button with the target in the sensing area.
Then press the SET button without target in the sensing
area, as illustrated at the right.
2. Set the threshold to the middle value between the values
obtained with and without the target.

RUN/ADJ Mode
The number of the incident level indicators lit depends
on the position of the target. When using the
manual-tuning function, it is possible to adjust the
threshold in six levels. The default threshold is set to 7.
