Product Overview

The SICK NAV2xx and NAV3xx 2D LiDAR sensors are designed for modern automated guided vehicles (AGVs) and autonomous mobile robots (AMRs), offering reliable, real-time position determination in industrial environments. These sensors combine precise measurement of natural landmarks with optional reflector detection to provide flexible localization solutions. The NAV product family delivers proven performance through integrated evaluation of measurement data, reducing computational load on vehicle systems while ensuring consistent operation. With robust enclosure ratings up to IP 67 and built-in heating, the sensors are suitable for both indoor and outdoor use—including cold storage applications—ensuring dependable performance in challenging conditions.

Key Features and Technology

The NAV series delivers flexibility through dual-mode localization: it captures natural contour data from the environment and optionally detects installed reflector positions. This mixed mode operation enables reliable navigation under varying conditions such as changing vehicle speed, surface characteristics, or dynamic ambient environments. The sensors support both technologies in a single variant, combining the robustness of landmark-based positioning with the precision of reflector-based tracking. This dual capability ensures effective localization for vehicles of different sizes and complexity, meeting today’s demands for adaptability and reliability in industrial automation.

Technical Characteristics

The NAV2xx sensors offer a scanning frequency of 25 Hz, with a working range up to 50 m. Detection reaches 30 m to reflectors and 18 m to targets with 10% remission. The NAV3xx models provide a larger scanning range at 8 Hz, with a maximum working range of up to 250 m, detecting reflectors up to 70 m and targets with 10% remission up to 35 m. Both series support output logging for contour data and/or reflector positions, enabling mixed mode navigation. The sensors are available in compact, lightweight designs ideal for small to medium-sized vehicles, ensuring reliable operation without compromising space or weight constraints.

Configuration and Integration

The NAV2xx and NAV3xx sensors integrate seamlessly into AGV and AMR systems through their support of mixed mode navigation. The SOPAS tool enables parameterization, visualization, layout determination, layout checking, and position calculation—facilitating easy setup and optimization. Contour data and reflector positions can be acquired simultaneously in the same sensor variant, allowing system designers to choose the most appropriate localization method based on application needs. This flexibility simplifies integration while maintaining high accuracy and reliability across diverse industrial environments.

Operating Environment

The NAV2xx sensors operate within an ambient temperature range of –30 °C to +50 °C, with an IP 67 enclosure rating providing full protection against dust and immersion in water up to 1 meter for 30 minutes. The NAV3xx models operate between 0 °C and +50 °C, also featuring IP 67 protection. Integrated heating ensures stable performance in cold environments, making these sensors suitable for outdoor installations or cold storage facilities where temperature fluctuations are common.

Industrial Applications

The NAV2xx series is ideal for small to medium-sized vehicles such as tuggers in warehouse logistics and cleaning robots. The NAV3xx models are designed for larger, more complex vehicles requiring extended scanning ranges. Both sensors support reliable localization through natural landmarks or reflector-based positioning, making them suitable for diverse industrial settings where precise navigation is essential. Their flexibility, reliability, and ability to operate under dynamic conditions ensure consistent performance in automated material handling and mobile robotics applications.
