Working Principle

The LMS500 works by:

• Emitting a rotating laser beam (905 nm)
• Measuring time-of-flight reflection from objects
• Producing a 2D point cloud (radar-like scan)

It can:

• Detect object distance
• Generate contour profiles
• Measure position, shape, and movement
• Support field monitoring and classification

Key Features

• 190° wide-angle 2D scanning
• Long measurement range up to 80 m
• High accuracy (millimeter-level)
• Multiple scan frequencies for different speeds
• Multi-echo detection (improves reliability in dust/fog environments)
• Real-time data output for PLC / PC systems
• Suitable for industrial harsh environments

Advantages

• Very stable measurement in warehouse and factory environments
• Works on most surface types (metal, wood, cartons, etc.)
• High-speed scanning suitable for moving objects
• Strong resistance to ambient light interference
• Ideal for automation and AGV navigation
• Reliable long-distance detection capability

Applications

• AGV / AMR navigation systems
• Warehouse logistics and pallet detection
• Volume and contour measurement
• Industrial area monitoring
• Collision avoidance systems (non-safety use)
• Conveyor and material tracking
• Robotics environment mapping

Precautions

• This is a measurement LiDAR, not a safety-rated scanner
• Dust, steam, or heavy contamination may affect accuracy
• Reflectivity of target affects detection distance
• Requires stable mounting (vibration affects scan quality)
• Correct configuration is required for field evaluation mode
• Not intended for human safety protection applications
