Transmissive Photosensors (Photo Interrupters)
CNA1015
Photo Interrupters
Unit : mm
Overview
CNA1015 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 : 0.3 mm
Gap width : 5 mm
