Overview

CNZ1102 and CNZ1108 are a photocoupler in which a high

efficiency GaAs infrared light emitting diode is used as the light

emitting element, and a high sensitivity phototransistor is used as

the light detecting element. The two elements are arranged so as to

face each other, and objects passing between them are detected.
