Trick number two

Pepperl+Fuchs expanding the future-oriented product architecture of its photoelectric sensors with R200 and R201 series.

With the R200 and R201 series, the future-oriented product architecture of photoelectric sensors from Pepperl+Fuchs enables applications with longer operating distances. Just like the compact R100, R101, and R103 series, the new series consistently offers all photoelectric functional principles in a slightly larger design. Standardised usage across all series is an especially highly-valued feature. This usage guarantees a high degree of operating convenience, security of investment, and increased efficiency, as well as the built-in, standardised IO-Link connection via the Smart Sensor profile — Pepperl+Fuchs is one of the first manufacturers to offer the latest version of the Smart Sensor prof    

Five designs, identical functional principles, standardised operation, powerful sensor technologies, and IO-Link in every version — the future-oriented product architecture of photoelectric sensors from Pepperl+Fuchs delivers universal solutions, simple integration and commissioning, and the highest level of efficiency and reliable planning. While the successful R100, R101, and R103 series were designed for shorter sensing and detection ranges, the new R200 and R201 series with medium-sized housing facilitate applications with longer operating distances. This not only reduces the complexity of choosing a sensor; users benefit from maximum flexibility in every application and installation option and, in particular, from the standardised usage across all series and functional principles.

Uniform operating concept for perfect usability

For all sensors, the uniform operating concept has been clearly thought out and optimally adapted to the relevant functional principle: All series offer an intuitive and identical look and feel during parameterization. This is thanks to the intelligent, functional symbiosis of a multiturn potentiometer and push button, which function as a single combined operating element. The sensitivity, switching threshold, and operating mode can be set using the rotary potentiometer. Selection of the switching type and teach-in of the switch point is performed using the button. Three LEDs show that the sensors are ready for operation, indicate the switching type, show the free light path for detection or distance measurement, indicate that the operating reserve has been reached, and indicate if the light beam has been interrupted. The look and feel of a R100 or R101 retroreflective sensor is the same as that of a light sensor with background suppression from the R103 product family, a measuring device with multiple switch points from the R200 series, or an R201 distance sensor. The operating environment never changes for the user; this makes parameterization during commissioning or even when changing to another series or a similar functional principle significantly easier.

Identical functional principles across all series

As with the R100, R101, and R103, the market-compatible and industry-standard mounting options of the housing designs in the new R200 and R201 series offer all photoelectric functional principles. Choose between thru-beam sensors, retroreflective sensors with polarisation filters 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 during planning in the construction department, or even directly before commissioning. To allow for this, all sensor series are equipped with standard electrical connection options: M8 or M12 connector plug, M8 or M12 pigtail, or cable outlet. Because of their typical, often hard-to-reach installation environment, the new R200 and R201 series feature swiveling connector plugs, which provide an optimal cable feed even in narrow machine structures, thus simplifying sensor integration.

Uniform integration using latest smart sensor profiles

IO-Link and sensor technology 4.0 represent networked, future-proof automation in the context of Industry 4.0, the smart factory and the IIoT, and is therefore on board as an integration option in the R200 and R201 series as standard. As a pioneer of IO-Link standardisation, Pepperl+Fuchs is one of the first manufacturers to deploy the latest IO-Link consortium version of Smart Sensor profiles published by the IO-Link consortium. The aim is to ensure standardised access to adjustment options, parameters, process values and diagnostic information for IO-Link sensors each with identical basic functionalities — independent of the manufacturer and the functional principle. The identical representation and evaluation of all sensors that, as in the case of R200 and R201, follows their specific, current Smart Sensor profile, enables the use of functional modules for simplified control system integration. Existing application programs can be re-used, reducing the amount of programming required. Due to the omission of manufacturer or device-specific data sheets, both the commissioning and the ongoing plant maintenance are simplified.

End-to-end IO-Link — and thus the option for cloud connection — makes the new R200 and R201 series a technically and economically future-proof investment, especially since Bluetooth-based SmartBridge technology from Pepperl+Fuchs means that they can be mapped, parameterised, and integrated into the cloud on mobile devices via the SmartBridge app.

Innovative on the Inside

With the DuraBeam laser technology and the MPT Multi Pixel Technology for distance measurement — both developments from Pepperl+Fuchs — the new R200 and R201 series boast a highly innovative interior. The eye-safe DuraBeam laser technology combines the benefits of LED emitters — long service life and extended temperature range — with the benefits of laser diodes — large sensing and detection ranges and more intensive beam quality. As a result, the laser sensors in all series in the future-oriented product architecture offer optimised energy efficiency and a longer service life at both very low and elevated operating temperatures without compromising detection performance, operating distances, and operating reserves. At the same time, DuraBeam laser sensors boast an impressive beam profile: The light spot on the object is circular and sharply defined — ideal for precise, location-independent detection and distance measurement for small objects.

The measuring 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 multipixel 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 the R10x and R20x series to measure the position of an object precisely and clearly distinguish it from the background.

"Standard" solution expertise: Standard housing designs suitable for mounting combined with DuraBeam laser technology, MPT Multi Pixel Technology and IO-Link provide the new R200 and R201 series with a range of application possibilities, which depend on longer, versatile operating distances and simplified usability, as well as safe detection behaviour and precise measurement.
