What this model is for
- Long-range observation and target location, where the return comes from a large or cooperative target under clear air.
- Payloads that must reach kilometres without an active illuminator.
- Integration into gimbals, sights and remote observation heads with an external power and data harness.
Integration notes
LRF1830C 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 RS-422 in the specification table; TTL/RS-422 alternatives i and the documented supply is DC 12 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 1.54 µm 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.
