Product Introduction

The RWB3-M Series is a compact, high-speed laser distance sensor designed for dynamic applications requiring discretion and speed. Unlike traditional red laser sensors, this unit employs an Invisible 905nm Laser, providing covert detection capabilities without visual interference, making it ideal for traffic monitoring, security surveillance, and military-grade applications.

It delivers exceptional performance on moving targets with a lightning-fast 1ms response time. The optical system is robust enough to measure low-reflectivity black targets (like coal) and even detect transparent glass surfaces, offering a versatile solution for diverse industrial needs.

Housed in a lightweight (150g), IP65-rated enclosure, the RWB3-M withstands harsh outdoor conditions, including strong sunlight (80,000 Lux) and extreme cold (optional -40°C). With flexible interface options (RS232/485, Analog), it seamlessly integrates into UAVs, AGVs, and industrial automation systems.
