SICK NAV350-3232 LiDAR Sensor 2D Laser Navigation - 250m Working Range

Product Introduction

The SICK NAV350-3232 is a high-end 2D LiDAR sensor specifically optimized for the high-precision navigation of automated guided vehicles (AGV) and autonomous mobile robots (AMR). Featuring a full 360° horizontal aperture angle and a massive working range of up to 250 meters, this sensor excels in both contour-based and reflector-based localization. The NAV350-3232 delivers highly accurate raw data and integrated navigation algorithms, providing a positioning accuracy of ±4 mm, making it the benchmark for internal logistics automation in large-scale industrial environments.

Global PLC Spare HUB's Insight

The NAV350-3232 is not just a distance measurer; it is a "Spatial Intelligence" unit. For field engineers, the standout feature is the integrated reflector memory, which offloads complex coordinate calculations from the vehicle's main controller. This allows the AGV to maintain millimetric accuracy while moving at higher speeds. From a field-service perspective, the unit's 86-year MTBF reflects its mechanical robustness—essential for vehicles operating 24/7. Its ability to simultaneously process both contour data and reflector landmarks provides a fail-safe redundancy critical for safety-informed navigation paths.

Target Equipment & Diagnostic Power

Technical FAQ (Field Experience & Selection)

• Q: How does the NAV350-3232 handle localization in environments where natural contours are sparse?
• A: In "empty" environments like high-bay warehouses, the sensor utilizes its reflector memory. By detecting high-remission stripes or cylinders (min. 80mm), it calculates its absolute position relative to these landmarks, ensuring ±4mm accuracy where contour-only scanners would drift.
• Q: Can this sensor be used as a safety component for personnel protection?
• A: No. The NAV350-3232 is a navigation and localization sensor. It is not a safety component as defined by machine safety legislation. It should be paired with certified safety laser scanners (like SICK microScan3) for collision avoidance.
• Q: What is the benefit of the 360° scanning angle compared to 270° scanners?
• A: The 360° view eliminates blind spots in the vehicle’s "awareness." This is critical for complex maneuvers such as crab-steering or rotating in place, as it allows the vehicle to maintain landmark locks in all directions simultaneously without losing its pose.
• Q: Selection Guidance: When is the NAV350-3232 preferred over the NAV200 series?
• A: Choose the NAV350-3232 for large-scale facilities requiring long-range detection (up to 250m) and the highest possible positioning accuracy. The 12,000 reflector memory capacity makes it the superior choice for massive, complex site layouts.
• Q: How does ambient light affect the 905 nm laser diode in outdoor-adjacent areas?
• A: While designed for indoor use, the module features internal optical filtering. However, for areas with direct sunlight, it is best practice to monitor the remission factor quality via the diagnostic interface to ensure the "statistical error" remains within the 15mm threshold.
