Overview
CNZ1111 and CNZ1112 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.
