May 29, 2014 - Offering precise distance measurement, regardless of surface texture, Multi-Ray LED Scanner R2100 combines Pulse Ranging Technology (PRT) with Ultra-IR LEDs and Multi-Ray Scan. Thisprovides 2D measurement over entire area for precise distance measurement and detection of irregular surfaces. Ultra-IR LEDsfeature 8 m operating range, without requiringreflector, and PRT sensors emit pulses of high-intensity light up to 250,000 times/sec.

New LED Scanner R2100 from Pepperl+Fuchs Delivers Distance Measurement Over Wide Areas, with No Moving Parts or Lasers

Photoelectric distance measurement sensor combines three breakthrough technologies in one revolutionary device to deliver precise distance measurement - regardless of surface texture

TWINSBURG, OH – Pepperl+Fuchs introduces the Multi-Ray LED Scanner R2100. The R2100 combines Pepperl+Fuchs’ exclusive 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.

“The R2100 is a revolutionary 2D distance measurement sensor with a host of innovative features that delivers significant and tangible benefits to users,” says Michael Turner, Product Manager – Photoelectric Sensing. ”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. Additionally, PRT is the most effective time-of-flight measurement technology available today and provides maximum precision and reliability over large distances and in the harshest ambient conditions.”

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 beam, 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.

Pepperl+Fuchs is a world leader in the design, manufacture and application of high quality factory and process automation products and services. Pepperl+Fuchs pioneered the development of proximity sensors 50 years ago, and has set the standard for innovation and quality ever since.
