LRF-H series — 905 nm single-point LiDAR distance sensors
Collision avoidance, profile measurement and industrial positioning: 100 to 1,500 m, 20 Hz to 1 kHz, 1 cm reported resolution, 15 to 20 g.

What this family is, in integration terms
A single-point LiDAR sensor is a complete measurement device: it emits, receives, timestamps and reports a distance over a serial link. The differences that matter in a build are the update rate (tens to hundreds of hertz instead of 0.5–10 Hz), the absence of a high-voltage bias supply on your board, and optics that are already aligned inside a sealed part.
- Reflectance appears twice in a datasheet. Where a sensor publishes 90 % and 10 % columns, the 10 % column is the real-world number — an AGV looks at a matte surface, not a retro-reflector.
- Update rate is not accuracy. 200 Hz with centimetre resolution is a good control input and a poor measuring instrument; decide which you are building.
- Ambient-light immunity (published in klx on several of these) decides outdoor usability far more than the headline range does.
Choosing inside this series
Range, mass and interface move together here: the longest-reach parts are the heaviest and run RS-422, while the lightest parts are short-range and run UART-TTL. Pick the two you cannot negotiate, then read the model page for the test condition behind the range figure — a 6-model series usually quotes several different targets.
