photo reflective sensor

Regular price LE 10.00


 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.
