PRODUCT DESCRIPTON
The ERDI LASER® LRF0609C 6km Laser Rangefinder Module is a compact, high-precision 1535nm eye-safe laser rangefinder using the time-of-flight (TOF) principle. Designed for UAVs, intelligent robots, and tactical or industrial systems, it delivers stable, fast, and accurate distance measurements with a simple TTL serial interface.
Key Advantages
• Long-range capability: Up to 6 km detection with ±2 m accuracy.
• High reliability: MIL-STD-810G compliant for vibration, shock, and extreme temperature operation.
• Advanced measurement features: Supports first/last target detection, range gating, and built-in self-test (BIST).
• Compact and integration-friendly: Lightweight ≤62 g, dimensions 55×48×32 mm, low power consumption (≤1.5 W average).
