Product overview
The ERDI LASER ERDILRF LR1200E4 is a laser rangefinder module for OEM integration, with applications including gimbals with E4 brackets, distance sensing for outdoor robots, and narrow-target measurement of poles and lines. Its 905 ± 5 nm laser provides a standard measurement range of 4–1,200 m; actual reach depends on the target and environment. Single-shot mode returns one distance, while continuous mode delivers repeated distance outputs at an adaptive 2–10 Hz. UART-TTL communication operates at 115200 bps, with custom interface configurations specified separately.
The module combines a resin aspheric lens, a 9.2 mm × 14.5 mm receiver aperture and beam divergence below 4 mrad. It weighs ≤10 g and operates from a 3.3–5 V supply at −20 °C to +55 °C, with storage permitted from −40 °C to +60 °C. Startup takes ≤ 200 ms, and sleep power consumption is less than 1 mW. IP67 protection applies only to the lens cavity, excluding the exposed board and complete host product. Each module is assembled, aligned, calibrated and accepted in-house in Chengdu.
