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
SPD1200N2 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.
