Frequently asked questions

How does the polarized beam in the 42KL-G1LBQ-F4 sensor improve detection?

The polarized beam in the 42KL-G1LBQ-F4 sensor is emitted with a specific polarization. The sensor's receiver is filtered to only detect light with the same polarization, significantly reducing interference from specular reflections off shiny surfaces. This leads to more reliable detection of objects.
