Pepperl+Fuchs launches new optical sensors for longer operating distances

Pepperl+Fuchs has launched a new series of medium-sized photoelectric sensors for applications with longer operating distances.

The R20x series offers all photoelectric functional principles: through-beam sensors, retroreflective sensors with a polarization filter or for clear object recognition, energetic diffuse mode sensors, sensors with background suppression and foreground suppression, measuring light barriers with two switch points, and distance sensors.

Each R20x sensor offers several mounting patterns in one industry-standard housing style. The new R20x sensors also feature rotatable connectors, which allows flexible installation, even in space-restricted applications.

The company said that with eye-safe DuraBeam laser technology, Pepperl+Fuchs’ R20x photoelectric sensors deliver maximum reliability and accuracy. DuraBeam laser technology from Pepperl+Fuchs combines the advantages of an LED emitter-long service life and extended temperature range-with the strengths of laser diodes-long detection and sensing ranges as well as a more intense beam quality.

It added that as a result, R20x laser sensors are more energy-efficient and last longer without compromising performance, even in extreme operating temperatures. Another benefit of DuraBeam laser sensors is their special beam profile, which casts a sharp, circular light spot on an object.

Multi Pixel Technology uses the benefits of geometric triangulation for distance measurement and enables highly accurate, reliable detection results at close range. The sensor’s light source generates an extremely bright light spot with a high energy density on the object and thus a reflection that is mapped on the receiving multi pixel array with maximum precision. Intelligent software algorithms use the position of the centre of the reflection on the array to calculate the exact distance to the object.

Standardized IO-Link connection via the latest Smart Sensor Profiles enables convenient and reliable integration of the sensors.
