LRF-VB series — 905/940 nm single-point LiDAR sensors
The smallest parts in the catalogue: 1.0 to 1.5 g, 9 to 50 m, up to 200 Hz. For indoor robotics, docking and short-range presence sensing.
| Model | Max range | Accuracy | Rate | Mass | Interface |
|---|---|---|---|---|---|
| LRF50VB | 50 m | ±0.05 m | 100 Hz | 1.3 g | UART-TTL |
| LRF22VB | 20 m | ±0.05 m | 200 Hz | 1.5 g | UART-TTL |
| LRF10VB | 9 m | ±0.05 m | 50 Hz | 1 g | UART-TTL |
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 3-model series usually quotes several different targets.
