How do micro photo sensors work and what are they used for?
Micro photo sensors have built-in amplifiers and are available in a variety of configurations, with modulated, non-modulated, and polarized light beams. They’re used to provide precise and stable sensing or positioning of materials, components, or assemblies. Some have integrated connectivity, like IO-Link and IP 67 environmental ratings. Uses for micro photo sensors include precision manufacturing
