Published measuring range (verbatim):
Catalog range 0.2–1,200 m. A 1,500 m night-time figure appears in the source under special conditions and 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

Handheld and portable instruments, golf and sport optics, and short-range surveying.
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

SPD1200N4 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 3.3–5 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.
