Pepperl+Fuchs Unveils New Optical Sensors for Longer Operating Distances - The R20x Series

Oct. 12, 2018
DuraBeam and Multi Pixel Technology Included on the New Series

Following the successful introduction of the compact, short-range R10x Photoelectric Series, Pepperl+Fuchs introduces a new series of medium-sized photoelectric sensors for applications with longer operating distance-the R20x series. This new series offers all photoelectric functional principles: thru-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.

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. 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. This makes them ideal for extremely precise detection and distance measurement of small objects.

Additionally, 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 center of the reflection on the array to calculate the exact distance to the object. This allows the measuring and switching light sensors of R20x series to measure the position of an object precisely and clearly distinguish it from the background.

Standardized IO-Link connection via the latest Smart Sensor Profiles enables convenient and reliable integration of the sensors. Smart Sensor Profile is a standard that aims to ensure the same basic functionalities across all IO-Link sensor manufacturers. This includes access to settings, parameters, process data, and diagnostics. All sensors that follow a specific Smart Sensor Profile display and evaluate process data the same way. This enables the use of function blocks for simple control integration. Existing user programs can be reused, which simplifies programming. Due to the omission of manufacturer or device-specific data sheets, both the commissioning and the ongoing plant maintenance are simplified.

The R20x series is the latest addition to Pepperl+Fuchs' forward-thinking family of photoelectric sensors.
