Product Overview

The SICK LMS1xx LiDAR sensor is a compact, robust infrared-based laser distance sensor designed for precise range detection in industrial environments. It operates using a 905 nm infrared light source to scan objects and measure distances with high accuracy across a working range of 0.5 m to 20 m. The sensor delivers reliable performance through its IP67-rated enclosure, ensuring protection against dust and immersion in water up to 1 meter for 30 minutes. With a lightweight design (1.1 kg) and compact dimensions (105 mm × 102 mm × 162 mm), it is ideal for integration into automated systems where space and durability are critical. The LMS1xx supports both Ethernet and serial communication, enabling flexible data transmission options for real-time monitoring and control in production lines or safety-critical applications.

Key Features and Technology

The LMS1xx utilizes a 905 nm infrared light source to emit laser pulses that scan the environment at scanning frequencies of 25 Hz or 50 Hz, providing consistent and repeatable measurements. Its angular resolution is specified as 0.25° or 0.5° in horizontal direction, depending on model configuration, enabling precise detection of object positioning. The sensor operates within a working range from 0.5 m to 20 m, with scanning performance defined at specific remission factors: 18 m at 10% remission and 20 m at 90% remission. This ensures reliable detection across varying surface reflectivity conditions. A response time of ≥20 ms allows for timely data acquisition in dynamic environments. The sensor is designed to operate under industrial conditions with minimal environmental interference, making it suitable for applications requiring stable and accurate distance sensing.

Technical Characteristics

The LMS1xx features a 905 nm infrared light source, operating at scanning frequencies of 25 Hz or 50 Hz. The horizontal angular resolution is either 0.25° or 0.5°. The working range spans from 0.5 m to 20 m, with scanning range defined as 18 m at a 10% remission factor and 20 m at a 90% remission factor. The sensor is supplied with one M12 round connector for mechanical and electrical connection. It operates within a supply voltage range of 10.8 V DC to 30 V DC, making it compatible with various industrial power systems. Housing color is gray (RAL 7032), and the enclosure rating is IP67 according to EN 60529, Section 14.2.7. The protection class is III as defined in EN 61010-1:2010-10. Weight is 1.1 kg, with dimensions of 105 mm × 102 mm × 162 mm (L × W × H). Response time is ≥20 ms. Data transmission supports Ethernet (TCP/IP) at 10/100 MBit/s and serial RS-232 at data rates from 9.6 kBaud to 115.2 kBaud for both read result output and service functions.

Configuration and Integration

The LMS1xx offers flexible integration via Ethernet (TCP/IP) or RS-232 serial interface, enabling seamless connection to industrial control systems such as PLCs or SCADA platforms. The Ethernet interface supports data transmission at 10/100 MBit/s for real-time readout of distance measurements and status information. RS-232 provides a service interface with data rates ranging from 9.6 kBaud to 115.2 kBaud, supporting both read result output and diagnostic functions. The sensor is designed for direct mounting using its standard M12 connector, allowing easy installation in automation equipment or robotic systems. Its compact footprint and standardized interfaces simplify integration into existing machinery without requiring extensive modifications. All communication functions are intended for use with compatible host devices that support TCP/IP or RS-232 protocols.

Operating Environment

The LMS1xx is designed to operate reliably in industrial environments with typical temperature and humidity conditions. It features an IP67 enclosure rating, ensuring complete dust protection and submersion resistance up to 1 meter for 30 minutes, making it suitable for use in wet or dusty settings. The sensor operates within a supply voltage range of 10.8 V DC to 30 V DC, allowing compatibility with various power sources commonly found in industrial automation. Performance may vary depending on environmental conditions such as ambient temperature, humidity, and surface reflectivity. It is important to note that the actual performance values are typical and may differ under extreme or non-standard operating conditions. The sensor meets protection class III requirements (EN 61010-1:2010-10), ensuring safe operation in high-voltage environments.

Industrial Applications

The LMS1xx is ideal for applications requiring accurate distance measurement and object detection in industrial automation. It can be used in material handling systems, robotic guidance, safety monitoring, and process control where precise range sensing is essential. Its ability to operate reliably across a wide range (0.5 m to 20 m) makes it suitable for detecting objects at varying distances. The sensor’s robust IP67 rating ensures durability in harsh environments such as manufacturing floors or outdoor installations. With support for both Ethernet and serial communication, it integrates easily into existing control systems. Applications include pallet detection, edge sensing, and presence detection in automated assembly lines where reliable and repeatable distance data is required. Performance may vary depending on environmental conditions, with actual values subject to change based on surface reflectivity and ambient factors.
