SICK LMS511-20100 2D Laser Scanner Infrared Outdoor

The SICK LMS511-20100 is a 2D laser scanner from the LMS511 PRO series. This unit handles both outdoor and indoor applications with equal capability. Specifically, the LMS511-20100 offers high resolution power for detailed environment scanning. The light source uses infrared at 905 nm (± 10 nm) for invisible detection. For perimeter monitoring and object detection, engineers choose this scanner. Outdoor infrastructure and industrial sites benefit from its rugged design.

Laser Safety and Aperture Angle

Regarding laser safety, the class reaches Class 1 per EN/IEC 60825-1:2014 standards. Compliance with EN 60825-1:2014+A11:2021 ensures complete eye safety. Consequently, no special laser safety equipment is needed during operation. The horizontal aperture angle measures 190° for wide area coverage. Due to this wide angle, the scanner suits large outdoor spaces. Ports, airports, and mining sites benefit from this extensive field of view.

Scanning Frequency and Angular Resolution

Six configurable scanning frequencies provide exceptional application flexibility. Available frequencies include 25 Hz, 35 Hz, 50 Hz, 75 Hz, and 100 Hz. Higher scan rates capture faster moving objects with better detail. On the other hand, lower scan rates provide more processing time per measurement. For angular resolution, eight different options are available. You can choose from 0.042° (interlaced), 0.083° (interlaced), 0.1667°, 0.25°, 0.333°, 0.5°, 0.667°, or 1.0°. Finer resolution detects smaller objects, yet it increases data output volume. The interlaced options provide enhanced resolution through multiple scans.

Scan Field Flatness and Conical Error

Turning to scan field geometry, the flatness combined measures ± 0.72° for consistent scanning. The typical conical error sits at 0.11° ± 0.1° at 1 sigma value. Because this error remains low, accurate positioning occurs across the entire scan field. The typical tilt measures 0.15° ± 0.08° at 1 sigma value. Even with minor mounting angle variations, reliable data is provided.

Heating System for Cold Environments

For cold weather operation, the LMS511-20100 includes self-heating with additional integrated heating. Standard self-heating maintains basic functionality in cool conditions. The additional integrated heating enables operation down to -30°C. Power consumption for heating reaches 55 W typical. Therefore, this scanner suits freezing outdoor environments reliably.

Working Range and Scanning Capabilities

Versatile coverage comes from a working range of 0.2 m to 80 m. At 10% remission factor, however, the scanning range reaches 26 m reliably. Darker objects with lower reflectivity will produce shorter effective ranges. Precise distance data comes from ± 12 mm measurement accuracy. Furthermore, the amount of evaluated echoes reaches 5 for superior reliability. Rejecting spurious reflections from rain, dust, or fog is possible with five echoes.

Spot Size and Beam Divergence

Regarding the laser beam, divergence measures 4.7 mrad for the emitted pulse. A 13.5 mm spot size appears at the viewing window. At 26 meters distance, however, the spot expands to 136 mm. At 40 meters distance, the spot size reaches 202 mm. Consequently, larger spots may average over small object features at long range.

Electrical Specifications and Power Requirements

For connections, the sensor includes 4 x M12 round connectors for various interfaces. The supply voltage requires 24 V DC with ± 20 % tolerance. Therefore, the acceptable range spans from 19.2 V to 28.8 V DC. Normal operation consumes 22 W of power for scanning. For heating, add 55 W typical in cold conditions. Total maximum consumption reaches approximately 77 W.

Mechanical Construction and Materials

AlSi12 aluminum alloy forms the housing for strength and heat dissipation. Easy identification comes from the gray (RAL 7032) housing color. For optical clarity, the window uses polycarbonate with scratch-resistant coating. Per EN 60529, Section 14.2.7, the enclosure rating reaches IP65 and IP67. Consequently, the sensor resists dust ingress and temporary immersion. For heavy rain and washdown, IP67 provides extra protection. Safety extra low voltage operation is ensured by Protection Class III per IEC 61140:2016-11.

Dimensions and Weight

Moving to physical size, the dimensions (L x W x H) measure 160 mm x 155 mm x 185 mm. Stable installation comes from a 3.7 kg weight. For this reason, use sturdy mounting brackets to support this weight securely.

Reliability and Performance Parameters

Regarding reliability, the MTBF exceeds 100 years for exceptional performance. Similarly, the MTTFD exceeds 100 years for safety-related calculations. Fast detection of moving objects comes from a ≥ 10 ms response time. Due to the active LiDAR principle, the detectable object shape is almost any.

Measurement Errors and Accuracy

Distance from the sensor affects the systematic error. From 1 m to 10 m, the error equals ± 25 mm. From 10 m to 20 m, however, the error expands to ± 35 mm. Distance also affects the statistical error accordingly. A 7 mm error appears from 1 m to 10 m. From 10 m to 20 m, the error equals 9 mm.

Integrated Application and Field Evaluation

Real-time zone monitoring comes from the field evaluation integrated application. Your control system receives continuous measurement data output. Complex zone definitions are supported by 10 field sets. For multiple independent monitoring tasks, 10 simultaneous evaluation cases are available. As a result, one scanner can protect ten different areas simultaneously.

Filter Options for Reliable Detection

Several filters improve detection reliability in challenging conditions. Spurious reflections from unwanted objects are rejected by the echo filter. Similarly, the fog filter improves performance in humid or misty environments. Small dust or debris particles are ignored by the particle filter effectively. Meanwhile, noisy measurements are smoothed by the average filter for stable output. Finally, interference from bright light sources is handled by the glare filter.

Communication Interfaces and Protocols

For networking, the LMS511-20100 includes Ethernet with TCP/IP and UDP/IP protocols. OPC server communication is supported for industrial integration. Host and AUX functions plus NTP time synchronization are provided. Fast data transfer comes from a 10/100 MBit/s transmission rate. Additionally, serial communication supports RS-232 and RS-422 standards. Host and AUX functions are also supported by this interface. From 9.6 kBaud to 500 kBaud, the data transmission rate ranges.

CAN interface serves for output extension and synchronization. Data transmission rates include 20 kBit/s, 500 kBit/s, and 1 MBit/s. For service access, USB with Mini-USB connector is available as a service interface.

Digital Inputs and Outputs

For external triggers, the scanner provides 4 digital inputs. These inputs support encoder (HTL) and synchronization functions. For alarm and status signaling, 6 digital outputs are available. For quick status checking, 5 LEDs serve as optical indicators. Additionally, error codes and configuration information appear on a 7-segment display.

Ambient Conditions and Object Remission

From 2% to > 1,000% including reflectors, the object remission range spans. Very dark objects (2% remission) produce the shortest detection ranges. In contrast, reflectors (>1,000% remission) produce the longest detection ranges. From -30 °C to +50 °C, the ambient operating temperature ranges with heating active. For warehouse conditions, storage temperature spans from –40 °C to +70 °C. Furthermore, 70,000 lx ambient light immunity ensures reliable operation in bright sunlight.

Environmental Compliance and Immunity

Regarding EMC, emitted radiation complies with IEC 61000-6-3:2020. For industrial environments, EN IEC 61000-6-3:2007+A1:2011 is also met. For immunity, compliance meets IEC 61000-6-2:2016 and EN IEC 61000-6-2:2019. Vibration resistance follows sine test at 10 Hz to 150 Hz. From 0.35 mm to 5 g, amplitude ranges for 20 cycles. For shock, resistance withstands 15 g at 11 ms for 6 single shocks per axis. Additionally, 10 g at 16 ms for 1,000 continuous shocks per axis is tolerated. Per DIN EN 50102:09-1997, impact resistance meets IK05, IK06, and IK07.
