Transmissive Photosensors (Photo Interrupters) CNA1003H Photo Interrupter For contactless SW, object detection Outline CNA1003H is a transmittive photosensor 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.
