Laser distance sensors for AGV, crane and industrial positioning

Short range, high rate, centimetre accuracy, and a price that survives being bought in hundreds.

The trade here is different

Below 100 m, 905 nm single-point LiDAR sensors do the job at 20–200 Hz and 1–15 g. The published two-reflectance figures matter: a 1,500 m sensor rated at 90 % reflectance is a 300 m sensor against a 10 % surface, and an AGV is usually looking at a 10 % surface.

Interface and integration

UART at 115200, 3.3–5 V supply, and a frame format that is usually documented in the module manual. For a safety function, remember that a single-point sensor is a measurement device, not a certified safety device: the safety function needs its own architecture.

Which models

The 9–50 m parts for docking and presence, the 200–600 m parts for crane and gantry anti-collision, and the kilohertz parts where the platform is moving fast.
