15-10-2020 · This weeks EYE on NPI is a sensor with a magnetic personality and we’re really attracted to it…You guessed it – we’re looking at the latest 3D magnetic field sensors from Melexis, the MLX90395.. These are some of the few high-magnetic-field sensors available, with up to +-120mT, that’s 1200 Gauss!
