■ Overview

CNZ1021, CNZ1023 and CNA1009H are a transmis-

sive photosensor in which a high efficiency GaAs infra-

red light emitting diode is used as the light emitting ele-

ment, and a high sensitivity phototransistor is used as

the light detecting element. The two elements are ar-

ranged so as to face each other, and objects passing be-

tween them are detected.
