Overview
CNZ2153 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 Si 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.
