I2C infra-red proximity sensor measures to 20µm movement or at 500mm range

This post was originally published on this site

Vishay has release of two high-resolution automotive grade optical reflective proximity sensors that operate down to 20µm for force sensing applications. In use, an infra-red beam is sent out and its reflection detected. Sensing can be from up-close to half a meter away, and can have enough resolution to detect the displacement of a surface …
