Product Overview

The SICK LMC1xx 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 measure distances from 0.5 m to 20 m with high accuracy. The sensor features a scanning frequency of 50 Hz and delivers reliable performance through its IP65-rated enclosure, ensuring protection against dust and water spray. With a signal housing color of white (RAL 9003), it offers both functional reliability and visual clarity in installation settings. Designed for integration into automation systems via Ethernet, RS-232, or CAN interfaces, the LMC1xx provides flexible connectivity options to meet diverse control system requirements. Its compact dimensions (105 mm x 102 mm x 152 mm) and lightweight design (1.1 kg without cables) make it ideal for space-constrained applications where reliable distance sensing is essential.

Key Features and Technology

The LMC1xx employs an infrared light source at 905 nm to detect objects within its working range, achieving a scanning resolution of 0.25° horizontally under standard conditions (0.5° at higher resolutions). The sensor operates at a scanning frequency of 50 Hz, enabling consistent and repeatable measurements. It detects targets based on the remission factor, with a defined scanning range of 18 m at a 10% remission factor threshold—indicating reliable detection under typical environmental conditions. This technology ensures accurate distance measurement even in dynamic environments where object reflectivity may vary. The sensor's response time is ≥20 ms, allowing sufficient time for processing and feedback in real-time control systems. Its use of infrared light ensures minimal interference from ambient visible light sources while maintaining high sensitivity to reflective surfaces.

Technical Characteristics

The LMC1xx has a working range of 0.5 m to 20 m, with a scanning range of 18 m at a 10% remission factor. The horizontal angular resolution is specified as 0.25° (typical), with a maximum of 0.5° depending on environmental conditions. It operates within a supply voltage range of 9 V DC to 30 V DC, making it compatible with various industrial power supplies. The sensor features a system plug with screw terminal block for secure connection and supports multiple communication protocols: Ethernet (TCP/IP with data transmission rate up to 10/100 MBit/s), RS-232 (data rates from 9.6 kBaud to 115.2 kBaud) for read output and service functions, and CAN for extension of outputs. All technical values are typical under standard conditions; actual performance may vary due to environmental factors such as temperature or ambient light.

Configuration and Integration

The LMC1xx is designed for seamless integration into industrial automation systems through multiple communication interfaces. It supports Ethernet TCP/IP for data transmission at 10/100 MBit/s, enabling remote monitoring and real-time data access from PLCs or HMIs. RS-232 provides a reliable serial interface with data rates ranging from 9.6 kBaud to 115.2 kBaud for both read result output and service functions. Additionally, CAN support allows extension of outputs for integration into complex control networks. The sensor includes a system plug with screw terminal block, simplifying wiring and ensuring secure electrical connections. These features allow flexible deployment in diverse automation scenarios—whether used standalone or as part of a larger sensing network—without requiring specialized hardware or software.

Operating Environment

The LMC1xx is rated for operation in environments with an IP65 enclosure (EN 60529, Section 14.2.5), providing complete dust protection and resistance to water spray from any direction. It operates under a protection class of III (EN 50178 (1997;10)), ensuring safe operation in high-voltage environments. The sensor is designed for use within ambient temperatures typically ranging from -25°C to +60°C, though specific performance may vary with environmental conditions. It is not rated for direct exposure to rain or immersion. Performance characteristics such as scanning range and angular resolution are subject to variation based on environmental factors including temperature, humidity, and surface reflectivity. The sensor's operation remains stable within its specified voltage range (9 V DC to 30 V DC), ensuring consistent performance across different power supply conditions.

Industrial Applications

The LMC1xx is suitable for a variety of industrial applications requiring precise distance measurement and object detection. It is commonly used in material handling, packaging, and robotic guidance systems where reliable range sensing is critical. Its ability to detect objects at up to 18 m with a defined remission factor makes it ideal for monitoring conveyor lines or detecting obstacles in automated workflows. The sensor’s compact size and robust construction support integration into tight spaces such as assembly stations or safety zones. With support for Ethernet, RS-232, and CAN interfaces, the LMC1xx can be easily connected to PLCs, SCADA systems, or supervisory control platforms. Its performance in dynamic environments ensures consistent operation across diverse industrial settings where object detection must remain accurate and responsive.
