Presence Detection of

With a wider beam, you can stably detect
powders and liquids because they are less likely
to fall outside of the beam.
Using a line beam allows you to detect caps that
are not attached correctly with only one Sensor.
The wide sensing area helps eliminate the
influences of color differences in the rubber sheet
to enable stable detection.
