A photoreflector that uses an infrared light-emitting diode on the emitting side and a photo IC/modulated photo IC on the receiving side.
The reflective photo sensor KR894 / light modulation type KR895 is a dust-proof photo reflector that uses an infrared light-emitting diode on the emitting side and a photo IC or modulated photo IC on the receiving side. Its dust-proof structure makes it easy to remove paper dust and allows for the detection of materials with low reflectivity, such as black paper and OHP film. The KR895, due to its light modulation method, is resistant to noise from ambient light and other disturbances. RoHS-compliant products are also available. It is suitable for applications such as paper detection in copiers, printers, and printing machines, as well as object passage detection in various automatic machines.
