Product Overview

The SICK LMS5xx LiDAR sensor is a high-precision, long-range laser-based distance measurement device designed for reliable performance in industrial automation environments. It delivers accurate 3D spatial data using infrared light at 905 nm with standard resolution power, enabling precise detection and scanning over distances from 0.2 meters to 80 meters. With a scanning frequency ranging from 25 Hz to 100 Hz, the LMS5xx offers flexible operation for diverse motion and object tracking applications. The sensor features a robust aluminum housing (AlSi12), IP65 or IP67 enclosure rating, and operates reliably under harsh conditions. Its compact dimensions (160 mm × 155 mm × 185 mm) and lightweight design (3.7 kg) make it suitable for integration into automated systems where space and durability are critical.

Key Features and Technology

The LMS5xx employs an infrared light source at 905 nm, ±10 nm, to generate high-resolution point cloud data with a horizontal angular resolution of 0.042° in standard mode, improving to up to 1° in lower-resolution interlaced modes. The sensor achieves a scan field flatness combined of ±0.72° and maintains measurement accuracy of ±24 mm under typical conditions. Typical conical error is 0.11° (±0.1°), while typical tilt is +0.15° (±0.08°), ensuring consistent performance across scanning angles. The sensor is built to withstand mechanical stress with a rated shock resistance of 15 g for 11 ms and 10 g for 1,000 continuous shocks per axis. Its response time is ≥10 ms, enabling real-time feedback in dynamic environments.

Technical Characteristics

The LMS5xx operates with a supply voltage of 24 V DC (±20%) and features a 4 × M12 round connector for secure electrical connection. It has a scanning range of 40 meters at a 10% remission factor, which defines the effective detection limit under low reflectivity conditions. Spot size divergence is 11.9 mrad, resulting in a spot diameter of 13.5 mm at the viewing window and expanding to 322 nm at 26 meters and 489 mm at 40 meters. The sensor supports Ethernet communication with TCP/IP and UDP/IP protocols, including Host and AUX functions and NTP time synchronization, delivering data transmission rates up to 10/100 MBit/s. All specifications are based on standard operating conditions as defined by SICK.

Configuration and Integration

The LMS5xx is designed for seamless integration into industrial automation systems via Ethernet connectivity, supporting TCP/IP and UDP/IP protocols with Host and AUX functions. The sensor enables real-time data transmission at up to 10/100 MBit/s, allowing direct communication with PLCs or control systems. Its 4 × M12 round connector ensures secure and reliable power and signal connections. With a standard resolution scanning capability and adjustable scanning frequencies (25 Hz to 100 Hz), the LMS5xx can be configured for applications requiring varying update rates. The sensor’s IP67-rated enclosure and robust housing material (AlSi12) ensure durability in demanding environments, while its gray RAL 7032 finish provides visual consistency in industrial settings.

Operating Environment

The LMS5xx is rated for operation in harsh industrial environments with an IP65 or IP67 enclosure rating (EN 60529, Section 14.2.7), providing complete dust and water resistance. It operates under protection class III (IEC 61140:2016-11) and is suitable for use in environments with high levels of contamination or moisture. The sensor functions reliably within a temperature range not specified in the provided facts, but its design ensures stability under typical industrial conditions. It is rated to withstand mechanical shocks (15 g, 11 ms; 10 g, 1,000 continuous shocks per axis), making it ideal for mobile or vibrating applications. The sensor's performance remains consistent across a range of environmental conditions, though actual values may vary due to ambient factors such as temperature and humidity.

Industrial Applications

The LMS5xx is well-suited for industrial automation tasks requiring precise distance measurement and object detection over long ranges. It is ideal in applications such as robotic navigation, automated guided vehicles (AGVs), machine vision systems, and perimeter monitoring where accurate 3D spatial data is essential. The sensor’s ability to operate at scanning frequencies from 25 Hz to 100 Hz allows for real-time tracking of moving objects or dynamic environments. Its high angular resolution and measurement accuracy (±24 mm) ensure reliable performance in complex scenes with varying object reflectivity. Applications include warehouse automation, assembly line monitoring, and safety systems where detection at distances up to 80 meters is required under standard conditions.
