photo reflective sensor wheel and can be connected directlyIntroduction: photo reflective sensor emits a light beam (visible or infrared) from its light emitting element. A reflective type photoelectric sensor is used to detect the light beam reflected from the target. A thrubeam type sensor is used to measure the change in light quantity caused by the target crossing the optical axis.
