Pepperl+Fuchs R202 series cubic photoelectric sensors

Click2Contact

The Pepperl+Fuchs R202 series cubic photoelectric sensors are designed for basic functions, utilising a red-light LED and a simple switching function with two switching outputs. Five function principles are available in a standardised housing design: thru-beam sensor, retroreflective sensor, retroreflective sensor for clear-object detection, diffuse mode sensor and diffuse mode sensor with background suppression.

The R202 series was developed with the special requirements of the material handling industry in mind. In pallet conveyor technology, for example, foil-wrapped pallets often have to be detected. With their reflective surfaces, they represent a challenge for the sensor technology used. The retroreflective sensor for clear-object detection was designed for such tasks: it operates without a dead band and is optimised for detecting shiny, reflective objects.
