Notes

Under strong ambient light or very high/low target reflectivity, error may increase: ±1 mm + 50 PPM.
Use a reflector for strong light environments or poor target reflectivity.
Operating temperature of -10–50 °C can be customized.
8 Hz is only available in fast continuous measuring mode.

Applications

Industrial automation: level/position measurement and conveyor alignment
Engineering surveying: point-to-point distance mapping and layout
Intelligent logistics and warehousing: navigation, sorting, and inventory level detection
Robotics (e.g., robot vacuum): obstacle distance measurement and avoidance
