Photo Interrupters
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)
5 mm (CNA1009)
The type directly attached to PCB ........... CNZ1021
