Correlation between sensing object size and sensing range Sensing field
CX-422 □
Diffuse reflective type
As the sensing object size becomes smaller than the standard
size (white non-glossy paper 200 × 200 mm 7.874 × 7.874 in ), the
sensing range shortens, as shown in the left graph.
For plotting the left graph, the sensitivity has been set such that
a 200 × 200 mm 7.874 × 7.874 in white non-glossy paper is just
detectable at a distance of 800 mm 31.496 in .

Correlation between lightness and sensing range
The sensing region is
represented by oblique lines in
the left figure.
However, the sensitivity should
be set with an enough margin
because of slight variation in
products.

Lightness shown on the left may
differ slightly from the actual
object condition.
For plotting the left graph, the sensitivity has been set such
that a 200 × 200 mm 7.874 × 7.874 in white non-glossy paper
is just detectable at a distance of 200 mm 7.874 in . Contact us
