Multi-Ray LED Scanner
Multi-Ray LED Scanner
Pepperl+Fuchs has introduced 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. 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.
