Reflective Photosensors
Overview
CNB1001 and CNB1002 are a small, thin SMD-compatible
reflective photosensor consisting of a high efficiency GaAs infrared
light emitting diode which is integrated with a high sensitivity Si
phototransistor in a single resin package.
Features
Reflow-compatible reflective photosensor
Ultraminiature, thin type : 2.7 × 3.4 mm (height : 1.5 mm)
Visible light cutoff resin is used
