ERDI TECH Launches Ultra-Compact 905nm Laser Rangefinder Module for OEM and Embedded Applications

MAIDENHEAD, U.K. - Aug. 4, 2025 - PRLog -- ERDI TECH LTD, a leading provider of laser sensing solutions, today introduced its latest innovation: a compact 905nm laser rangefinder module engineered for precision, reliability, and integration into space-constrained platforms such as drones, robots, handheld devices, and smart industrial systems.

Measuring only 26×25×14.5 mm and weighing just 11g, the new module achieves up to 1500 meters of range on high-reflectivity targets, while maintaining Class 1 eye safety compliance (IEC 60825-1). It combines low power consumption, high-speed ranging (1–3Hz), and robust environmental resilience, offering a breakthrough for developers seeking lightweight and efficient distance measurement solutions.

"This product reflects our ongoing commitment to enabling compact intelligent sensing systems," said a senior engineer at ERDI TECH. "It delivers performance typically found in larger systems, but in a form factor that fits modern edge devices."

Key Features:

• Laser Specs: 905±10nm wavelength, 3×6mrad divergence, 8.43mW average power
• Measurement Range: 5m to ≥1500m (visibility ≥6km, 70% reflectivity)
• Accuracy: ±0.7m @ ≤200m; ±(0.7 + 0.0004*d) @ >200m
• False Alarm Rate: ≤1%, Accuracy Rate: ≥98%
• Interface: UART (TTL_3.3V), multiple baud rate options (9600~57600bps)
• Power Efficiency: ≤0.5mW standby; ≤1.5W operating (@25°C)
• Startup Time: ≤550ms
• Durability: Shock 1200g, vibration 2.5g, operating temperature –20°C to +70°C
• MTBF: ≥1500h
