magnetic system design and current measurement solutions
The C-Core is designed for high-speed contactless current sensing in combination with a magnetic field sensor, i.e., Hall sensor, and a current conductor. Furthermore the core protects the sensor from parasitic magnetic fields caused by nearby conductors or other magnetic field sources.
