Description
About This Product
The LW20/HA combines long-range measurement with high accuracy in a compact IP67-rated enclosure. It is designed for applications where reliable distance sensing is required while keeping the sensor small and lightweight.The sensor can measure up to 100 m and provides accuracy better than 1 cm under specified temperature conditions. Its first- and last-pulse processing helps maintain useful measurements in challenging environments such as dust, mist, fog, rain and snow.
