Technical Overview

High-resolution 2D LiDAR sensor with 0.2-80m range, 5-echo technology, 190° aperture angle, 25-100Hz frequency, IP67 rating, and integrated heating system.

Key Features

  • High-resolution variant with a wide working range of 0.2 m up to 80 m [1.1.1]
  • Supports SICK's advanced 5-echo technology to provide high reliability under adverse weather conditions
  • Offers adjustable scanning frequencies from 25 Hz up to 100 Hz
  • Horizontal aperture angle of 190° with fine angular resolutions down to 0.042°
  • Rugged IP65/IP67 AlSi12 aluminum housing with scratch-resistant polycarbonate cover window
  • Integrated self-heating system allows operation in ambient temperatures down to -30 °C
  • Includes 4 x M12 round connectors for robust and reliable electrical connectivity

Industrial Applications

1. Outdoor Perimeter Intrusion Detection & Security

High-reliability monitoring of critical infrastructure perimeters, sub-stations, and airport borders in all weather conditions.

Problem Solved

Traditional sensors trigger false alarms during bad weather (heavy rain, fog, snow) or fail due to extreme cold temperatures. The LMS511 PRO resolves this with its integrated 5-echo measurement technology which filters out environmental noise, alongside its built-in self-heating system that ensures uninterrupted operation down to -30 °C.

2. Anti-Collision and Positioning for Port Gantry Cranes

Collision avoidance and high-accuracy positioning of massive ship-to-shore and rubber-tired gantry (RTG) cranes in port environments.

Problem Solved

Cranes operating in seaside environments face severe weather, salty sea spray, and require reliable distance measurement over wide areas to avoid colliding with other equipment or containers. The LMS511-20100 PRO's ±12 mm measurement accuracy, robust AlSi12 housing material, and IP67 rating protect the device from corrosive saltwater while its 190° horizontal aperture angle provides excellent field-of-view scanning.

3. Volume Measurement and Profiling on Bulk Material Conveyors

High-speed 3D volumetric scanning of bulk materials (such as coal, ore, or wood chips) on outdoor conveyor belts.

Problem Solved

In mining and quarrying, bulk materials generate immense dust, and conveyor speeds require rapid sampling to calculate volumes accurately. The LMS511-20100 PRO handles this via its high scanning frequency (up to 100 Hz) and fine angular resolution (down to 0.042°), which enables precise profiling, while its 5-echo technology easily penetrates thick dust clouds.
