Product overview
The ERDI Laser ERDILRF LR1000E4 laser rangefinder module supports OEM integration in UAV and gimbal payloads, handheld instruments, and sports and construction meters. Its standard measurement range is 4–1,000 m, with actual reach dependent on target and environment. Single-shot operation reports one distance, while continuous operation delivers completed distance outputs at an adaptive 3–10 Hz. Accuracy is ±1 m at D ≤ 400 m and ±(1 + 0.001D) m at D greater than 400 m, using 90% reflectivity whiteboard targets measuring 2.3 × 2.3 m and 2.3 × 4.6 m respectively.
The E4-format module incorporates a resin aspheric lens, a 9.2 mm × 14.5 mm receiver aperture and laser beam divergence below 9 mrad. Nominal dimensions are 25.7 × 14.2 × 26.2 mm, with individual drawing tolerances applying; rounded nominal dimensions alone are not suitable for machining. Weight is ≤10 g. IP67 protection applies only to the lens cavity and does not cover the exposed board or complete host product. Each module is assembled, aligned, calibrated and accepted in-house in Chengdu.
The standard UART-TTL interface operates at 115200 bps; custom interface configurations are specified separately. The module requires a 3.3–5 V supply, with operating power consumption ≤1 W, short-range consumption less than 0.6 W, standby consumption less than 0.3 W and sleep consumption less than 1 mW. Startup time is ≤200 ms and inrush current is less than 350 mA. Operating temperature spans −20 °C to +55 °C, with storage from −40 °C to +60 °C. The module has Class 1 laser classification under IEC 60825-1; finished-product classification depends on its optical path and configuration.
