What this model is for
- Close-range distance sensing: robotics, AGV and AMR docking, level and position feedback.
- Presence and gap measurement at centimetre resolution inside a machine envelope.
- High-rate short-range scanning where the update rate matters more than reach.
Integration notes
LRF22VB is a bare module, not a finished instrument: it arrives with an electrical interface and a mechanical envelope, and your product owns the optics, the housing and the safety case. The documented interface is UART/IIC and the documented supply is 3–3.6 V DC. Where a figure above is a limit (≤ / ≥), treat it as the manufacturer's statement and confirm the acceptance test in your own build rather than assuming margin.
For a 905 nm rangefinder, the laser safety classification of the finished product is the integrator's responsibility: the module document states its own classification, and the accessible emission of your assembled unit must be assessed separately.
How LRF22VB differs from LRF10VB
