Optical sensors from Pepperl+Fuchs are available in several varieties
The R200 and R201 series photoelectric sensors use DuraBeam laser technology and precision Multi Pixel Technology (MPT) for longer operating distance measurement. They include through-beam sensors, retroreflective sensors with a polarization filter, energetic diffuse mode sensors, sensors with background and foreground suppression, light barriers measured with two switch points, and distance sensors.
