Overview
CNZ1021 series is a transmissive photosensor series 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.

Features
● Position detection accuracy : 0.25 mm
● Gap width : 3 mm (CNZ1021, CNZ1022, CNZ1023)
