Published measuring range (verbatim):
Catalog range: 0.2–1,200 m. Sources also report a 1,500 m night-time maximum under special conditions; it is not a guaranteed range.
Range figures hold only under the conditions printed above. Atmospheric visibility, target size and target reflectance move the number by a large factor; we will not extrapolate a range to a target the manufacturer did not test.

What this model is for

Integration notes

SPD1200S2 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 3.3V~5V. 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.
