A
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.
