LPB40B IP65 DToF Single-Point Ranging LiDAR Sensor (0.05-40m, UART)

The LPB40B Single-Point Ranging LiDAR is a high-precision distance measurement sensor built on advanced Direct Time-of-Flight (DToF) technology. Designed for robust performance in demanding environments, it delivers stable, accurate distance readings even under strong outdoor lighting up to 100 klux, making it suitable for both indoor and outdoor applications.

With a range of 0.05–40 m, high full-range accuracy of ±5 cm, and an adjustable measurement frequency from 1 to 2000 Hz, the LPB40B excels in high-speed detection scenarios such as drone altitude hold, vehicle collision avoidance, smart transportation systems, and industrial sensing. Its UART output ensures easy integration with platforms like Arduino via IO expansion boards.

Built for reliability, the LPB40B features an IP65-rated enclosure, a durable coated crown-glass lens, and built-in protection against reverse polarity, overvoltage, and overcurrent. Certified with CE, FCC, RoHS, and FDA, it meets stringent safety and performance standards for professional and industrial use.
