Transmissive Photosensors (Photo Interrupters)
CNZ1179
(ON1179)
Photo Interrupter
Unit : mm
For contactless SW, object detection
Overview
CNZ1179 is a photocoupler 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.
