Diffuse Reflective Photoelectric Sensor PTL-BC80DPRT3-D Infrared LED and high detection accuracy

A diffuse photoelectric sensor, also known as diffuse-reflective sensor is an optical proximity sensor. It uses the principle of reflection to detect objects in its sensing range.The sensor has a light source and a receiver housed in the same package. The light beam is emitted towards the target/object and reflected back to the sensor by the target.The object itself acts as a reflector, eliminating the need for a separate reflector unit. The intensity of the reflected light is used to detect the presence of the object.
