The C-shield is a soft ferromagnetic core featuring superior material characteristics such as high linearity and very low hysteresis.


The shield is designed for contactless current sensing in combination with a magnetic field sensor, i.e., Hall sensor, and a current conductor. Furthermore the shield protects the sensor from parasitic magnetic fields caused by nearby conductors or other magnetic field sources.
