A photoreflector that uses an infrared light-emitting diode on the emitting side and a modulated phototransistor light-receiving element on the receiving side.
The KR3330 reflective photo sensor, light modulation type, is a dust-proof photo reflector that employs an infrared light-emitting diode on the emitting side and a modulated photo IC light-receiving element 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. Due to its light modulation method, it is resistant to noise from ambient light and other disturbances. It has a wide detection range and is a low-cost option. Additionally, RoHS-compliant versions are available. It is suitable for applications such as paper detection in copiers, printers, and various automatic machines for object passage detection.
