C8-6.25-8 Laminated Flux Concentrator

Description

The C-Core is a laminated soft ferromagnetic core featuring superior material characteristics such as high linearity and very low hysteresis. It is available with two different materials: Ni- Fe and Si-Fe. The 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.
