PRODUCT DESCRIPTON
The ERDI LASER® LRF2000A is a compact semiconductor short-pulse Laser Distance Sensor, weighing only 11 g, capable of accurately measuring distances from 5 to 2000 m on building-type targets. It delivers stable and reliable ranging performance for drone laser systems, surveying tools, and industrial automation.
Key Advantage
-
High-Precision Ranging: 5–2000 m measurement range with ±0.7 m accuracy at short distances (≤200 m) and ≤1% false alarm rate.
-
Compact Rangefinder Module: Dimensions 26×25×14.5 mm, 11 g, tested for outdoor use and wide-temperature operation.
-
OEM Laser Module: Equipped with UART (TTL_3.3V) interface, PC configuration software, and standardized command protocols for easy customization.
