Overview
CNZ1122 and CNZ1128 are a photocoupler in which a visible
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.
