C-Shape Flux Concentrator

Click here to send inquiry


The C-shape is a soft ferromagnetic flux concentrator featuring superior material characteristics such as high linearity and very low hysteresis. The shape is designed for planar current sensing in combination with a magnetic field sensor, i.e., Hall sensor, AMR sensor and a busbar conductor. The C-shape protects the sensor from parasitic magnetic fields caused by nearby conductors or other magnetic field sources while at the same time it enhances sensitivity and signal-to-offset ratio of the sensor.
