About this product

TFA300 is the enclosed IP67 member of the TFA300 single-point LiDAR family, intended for UAV sensing and other long-range measurement integration. Its datasheet lists 270 m at 90% reflectivity under 100 klux, a typical mass of 34.5 g excluding cables, and command-switchable UART/CAN. Both forms support configurable output up to 10000 Hz with the manual’s high-rate communication requirements; this does not establish maximum range at maximum rate.
