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

Screw-fastened type (both sides) ............. CNZ1022

Screw-fastened type (one side) ................ CNZ1023

The type directly attached to PCB ........... CNA1009
