May 19, 2014 - Pepperl+Fuchs introduces R2100 Multi-Ray LED Scanner R2100. The R2100 combines Pulse Ranging Technology (PRT) with Ultra-IR LEDs and Multi-Ray Scan. This technology combination delivers two-dimensional measurement over an entire area rather than just one point to ensure precise and reliable distance measurement and detection of irregular surfaces. As a result, it is an ideal solution for challenging indoor and outdoor mobile equipment, intralogistics and machine and plant engineering applications where unique surfaces need to be accurately and reliably detected. Multi-Ray Scan eliminates the need for moving parts that over time can break down or wear out. Ultra-IR LEDs deliver an 8 meter operating range without requiring a reflector, and they produce a larger light spot than laser emitters – a distinct advantage when detecting objects with irregular surfaces or textures. Sensors with PRT emit a very short, high-intensity light pulse. They calculate object distance based on the speed-of-light constant and time-of-flight of the reflected light pulse. Unlike other time-of-flight sensors that transmit a continuous light ray, PRT sensors emit short pulses of high-intensity light up to 250,000 times per second. Compared to a continuous source that uses lasers, the energy density of one PRT LED pulse can be up to 1,000 times greater. This allows stable and highly reliable detection, even at distances of 300 meters or more. In contrast to triangulation-based sensors, the detection range of a PRT sensor is not limited by the geometric layout of the sensor optics. Consequently, PRT sensors with smaller housings can be used for significantly larger detection ranges – providing impeccable measurement quality. Application Examples The R2100 is perfectly suited to detect the mowing edge on harvesters. With Multi-Ray Scan (multiple emitter elements arranged side-by-side span a 2D area over 88 degrees), the LED Scanner ensures precise guidance along the harvesting line and provides reliable measurement results, even on uneven agricultural landscapes. Additionally, the sensor has no moving parts to break down or wear out over time. This lack of moving parts also promises extra durability, ruggedness and measurement stability. The R2100 is also ideal for automated storage and retrieval (ASRS) tasks in the material handling and logistics industries. Lightning-fast PRT guarantees fast response times for rapid processes. Eye-safe Ultra-IR LEDs and no moving parts result in low power consumption and allow operation over a wide range of temperatures – without any additional cooling equipment needed.
