T.R;;;
CNB1009 (ON2173)
Reflective Photosensor
Overview
CNB1009 is a photosensor detecting the change of reflective light in which a high efficiency GaAs infrared light emitting diode is used as the light emitting element, and a high sensitivity Si phototransistor is used as the light detecting element. The two elements are located parallel in the same direction and objects are detected when passing in front of the device.
Features Fast response : tr, tf = 6 µs (typ.) Small size, light weight
Applications Detection of paper, film and cloth
