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.
