With their excellent repeatability, our through-beam light barriers are ideal for positioning tasks. They detect objects regardless of surface, color and material. The transmitter and receiver are in separate housings. Long ranges are no problem for the light barriers. They have a large functional reserve and are very resistant to dirt.
