Red light source high output reflective
photosensor (photoreflector)
RPR-220UC30N
The RPR-220UC30N employs a red light source which peak emitting wavelength is λp=630mm in the emitting side.
Therefore, it enables not only to judge whether it is an object with conventional function or not, but also to distinguish a
cyanogens color due to its complementary. Peak sensitivity wavelength which is λp=600nm also goes very well with the
receiving side.
