Transmissive Photosensors (Photo Interrupters) CNZ1021,CNZ1022,CNZ1023,CNA1009 Photo Interrupters Overview Features 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.
