LR1200E4 Laser Ranging Module, 905nm High Precision Laser Distance Sensor, Compact 1200m Long Range Laser Rangefinder Module

The ERDI LASER LR1200E4 is a high-precision, compact laser ranging module designed for demanding measurement applications. Operating at a 905 nm wavelength, it delivers a measurement range of approximately 13 to 3,937 feet, with a maximum nighttime range of up to 4,921 feet. The module features a fast 2–10 Hz refresh rate, customizable to meet specific requirements, and achieves a measurement accuracy rate of 98% or greater with a false alarm rate of just 1% or less. Weighing under 0.35 oz and measuring roughly 1.01" x 0.56" x 1.03", it integrates seamlessly into handheld devices such as night vision equipment, thermal imagers, telescopes, and laser illuminators. The UART-TTL communication interface supports easy secondary development, and the module is rated IP67 for protection. It operates between -4°F and 131°F and supports both single and continuous measurement modes. Ideal for border security, aviation, railway systems, law enforcement, and outdoor sports applications.
