Reflective Photosensors (Photo Reflectors)
CNZ2179
(ON2179)
Reflective Photosensor
Unit : mm
Overview
CNZ2179 is a reflective photosensor with a long focal distance,
in which a high efficiency GaAs infrared light emitting diode is used
as a light emitting element and a high sensitivity Si phototransistor
is used as the light detecting element.
