Sensing range L (mm in)
Correlation between lightness and sensing range
The sensing region is represent-
ed by oblique lines in the left
figure. However, the sensitivity
should be set with enough mar-
gin because of slight variation in
products.
Lightness shown on the left
may differ slightly from the
actual object condition.
()
The bars in the graph indicate the
sensing range for the respective
material. However, there is a
slight variation in the sensing
range depending on the product.
Further, if there is a reflective
object (conveyor, etc.) in the
background of the sensing object,
since it affects the sensing,
separate it by more than twice the
sensing range shown in the left
graph.

Distance to convergent point
The sensing region is represent-
ed by oblique lines in the left
figure. However, the sensitivity
should be set with enough mar-
gin because of slight variation in
products.
The graph is drawn for the
maximum sensitivity setting.
The bars in the graph indicate the
sensing range for the respective
material. However, there is a
slight variation in the sensing
range depending on the product.
Further, if there is a reflective
object (conveyor, etc.) in the
background of the sensing object,
since it affects the sensing,
separate it by more than twice the
sensing range shown in the left
graph, or adjust the sensitivity
adjuster.
The graph is drawn for the
maximum sensitivity setting.

Sensing range L (mm in)
As the sensing object size becomes smaller
than the standard size (white non-glossy paper
100100 mm 3.9373.937 in), the sensing
range shortens, as shown in the left graph.
