CNZ2179 (ON2179)
Reflective Photosensor
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.
Features
Long focal distance : 6 mm (typ.)
Visible light cutoff resin is used
