SICK LMS531-11100 Security 2D Laser Scanner – Cost-Effective Outdoor LiDAR 80m
- The LMS531-11100 Security is a 2D laser scanning LiDAR (LMS5xx Lite series) designed for cost-optimized indoor and outdoor security applications.
- It provides a detection range up to 80 m with a 190° scanning angle, suitable for standard perimeter monitoring and access control.
- Key performance characteristics include up to 75 Hz scan rate, 0.25° angular resolution, and support for 2-echo signal processing.
- Supports up to 4 independent monitoring fields, making it suitable for standard security zoning and basic intrusion detection scenarios.
- Industrial-grade design with IP65/IP67 protection, integrated heating, and stable operation from -30°C to +50°C.
- Communication interfaces include Ethernet TCP/IP, UDP/IP, and USB, enabling flexible integration with monitoring and control systems.
- Typical applications: perimeter security for warehouses and factories, indoor safety zones, AGV/robot navigation, gate access control, and logistics/port monitoring.
- Compared to the PRO version, the Lite model trades performance (fewer fields, lower resolution, fewer echoes, lower max scan rate) for lower cost and simplified deployment.
- Best suited for standard security systems where cost efficiency is prioritized over high-resolution multi-zone monitoring or extreme environmental requirements.
The LMS531-11100 Security is a 2D laser scanner (LiDAR) designed by SICK (Germany) for indoor and outdoor security applications, featuring an 80m scanning range, 190° aperture, 4 simultaneous field sets, and Ethernet TCP/IP plus UDP/IP connectivity.
1. Overview of the LMS531-11100 Security 2D Laser Scanner
The LMS531-11100 Security is a 2D laser scanner from SICK’s LMS5xx Lite series, designed for security applications indoors and outdoors at an optimized cost point. Despite being the Lite variant, it maintains the same 80m range, 190° aperture angle, and IP65/IP67 rating as the PRO version.
The key differences of the LMS531-11100 Security compared to the PRO variant are its 4 field sets (vs. 10), 2-echo evaluation (vs. 5), and maximum scanning frequency of 75Hz. This makes it the ideal choice for standard security applications that do not require extremely high angular resolution or a large number of simultaneous monitoring zones.
5 Key Specifications:
- Maximum scanning range: 80m (40m at 10% remission)
- Aperture angle: 190° horizontal
- Scanning frequency: 25 / 35 / 50 / 75 Hz
- Enclosure rating: IP65 / IP67 – integrated self-heating
- Connectivity: Ethernet TCP/IP and UDP/IP

3. Industrial Applications of the LMS531-11100 Security
With an 80m scanning range, 190° aperture, IP67 rating, and integrated self-heating, the LMS531-11100 Security Lite is the cost-optimal choice for the following security and industrial applications:
- Standard perimeter security monitoring: Detects intrusion within an 80m radius with 4 independent monitoring zones. Suitable for basic electronic fencing at warehouses, industrial zones, and office facilities.
- Indoor workplace protection: Detects personnel and objects in controlled areas. Ethernet UDP/IP enables fast integration with existing monitoring systems.
- AGV and indoor robotics: Supports environmental scanning and obstacle detection for autonomous vehicles in medium-sized warehouses, at a lower deployment cost than the PRO variant.
- Gate and access control: Detects and counts people/vehicles at factory gates, shopping centers, or restricted areas. Relay outputs connect directly to electric gate systems.
- Port and logistics environment monitoring: Monitors cargo loading/unloading areas and detects unauthorized personnel in forklift operating zones.
