The RWB2/B2 Series is a robust, high-speed laser distance sensor designed for heavy-duty industrial and outdoor applications. With measurement ranges extending up to 200 meters, it utilizes a highly efficient optical system to detect challenging targets, including black coal, dark powders, and transparent glass surfaces.
What sets this sensor apart is its speed and environmental adaptability. It offers a lightning-fast response time of 0.1ms (up to 10kHz), allowing for the dynamic measurement of high-speed moving objects. Engineered for the harshest conditions, it boasts an IP68 protection rating and can withstand 200,000 Lux of ambient light, making it immune to direct sunlight interference.
The large beam spot (20cm @ 100m) ensures stable averaging on rough surfaces like aggregate piles. Equipped with versatile interfaces including RS485, 4-20mA, and optional Ethernet, the RWB2/B2 Series is the ultimate solution for port logistics, mining automation, and outdoor perimeter security.
