  1. 2009/01/30 RPR-359F - Reflective photosensor (photoreflector)
Description
The RPR-359F is a  reflective photosensor. The emitter is a GaAs infrared light emitting diode and the detector  is a high-sensitivity, silicon planar phototransistor. A plastic lens is used for high sensitivity. In addition, since it is molded in plastic with a visible light filter, there is almost no effect from stay light.
 
Features 
*A plastic lens is used for high sensitivity.
*A built-in  visible light  filter minimizes the influence of stray light.
*Low collector-emitter saturation voltage.
*Lightweight and compact.

Application
*Copiers, Compact disc players
