SICK LMS511-21100 Industrial Grade 2D LiDAR Sensor

The SICK LMS511-21100 Lite is a rugged 2D LiDAR sensor designed for industrial environments, delivering a broad 190° horizontal scan and a working range from 0.2 m up to 80 m. It employs an infrared (905 nm) light source, is classified as laser Class 1 under IEC 60825-1, and includes built-in heating to maintain performance in varying temperatures. The LMS511-21100 Lite offers selectable scanning frequencies of 25, 35, 50, or 75 Hz and angular resolutions of 0.25°, 0.5°, or 1°, enabling a balance between detection density and update rate. With a maximum range of 26 m at 10% reflectivity, and a spot size of 4.7 mrad, it can reliably detect obstacles across a wide workspace, supported by fog correction to improve measurements in dusty or humid conditions. The sensor can evaluate up to 22 echoes per scan, providing robust profiling of target shapes, and typical applications include outdoor and indoor sensing in industrial automation. The LMS511-21100 Lite is cataloged as part number 1054154, representing the Lite variant of SICK’s LMS5xx 2D LiDAR family, which are widely used for navigation, obstacle avoidance, and area monitoring tasks in mobile systems and fixed installations alike.
