What this model is for

- Collision warning and industrial distance measurement at metre-to-kilometre scale.
- Cost-sensitive OEM builds where a 905 nm source and a small aperture are acceptable.
Integration notes
LR1200D23 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 - TTL, customizable and the documented supply is 3.3 V – 5 V (recommended supply voltage ≥ 3.5 V). 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.
