CNZ2253 (ON2253)
Reflective Photosensor
Overview
CNZ2253 is a photosensor detecting the change of reflective light
in which a high efficiency GaAs infrared light emitting diode is used
as the light emitting element, and a high sensitivity Si Darlington
phototransistor is used as the light detecting element. The two
elements are located parallel in the same direction and objects are
detected when passing in front of the device.
Features
High sensitivity
Small size and light weight
Applications
Detection of paper, film and cloth Optical mark reading
