This document describes the features and characteristics of Transmissive Photosensors (Photo lnterrupters), including highly precise position detection and gap width.
This document provides technical specifications and characteristics for the Panasonic CNZ1021, CNZ1023, and CNA1009H photo interrupters. These devices utilize a high-efficiency Gallium Arsenide (GaAs) infrared light-emitting diode and a high-sensitivity phototransistor to detect objects passing between them for contactless switching and object detection applications.
