PRODUCT DESCRIPTON
The ERDI LASER® LRF3000A1 is a compact 905nm laser rangefinder module designed for precise distance measurement up to 3000 meters. Featuring Class 1 eye-safe laser technology, high measurement accuracy, UART TTL communication, and ultra-lightweight design, this laser distance sensor provides a reliable ranging solution for UAV payloads, EO/IR systems, robotics, autonomous platforms, and industrial applications.
Key Advantage
- 3km Long-Range Measurement: Supports ranging distances up to 3000m on building targets with high measurement reliability.
- Ultra-Compact & Lightweight Design: Only 12g with a compact size of 13.5×25.1×27.8mm, ideal for UAV and embedded systems.
- Class 1 Eye-Safe 905nm Laser: Uses 905nm Class 1 laser technology (IEC 60825-1) for safe and reliable distance sensing.
- Easy System Integration: Supports UART TTL interface, compatible with UAV controllers, EO/IR payloads, and embedded platforms.
- Low Power & Fast Response: Optimized for battery-powered applications with operating power as low as ≤1.6W.
- IP67 Rugged Protection: Designed for outdoor environments with strong resistance to dust, water, vibration, and shock.
