magnetic system design and current measurement solutions
The U-Shield is a soft ferromagnetic shield featuring superior material characteristics such as high linearity and very low hysteresis.
The shield is designed for planar current sensing in combination with a magnetic field sensor, i.e., Hall sensor, AMR sensor and a busbar conductor. The U-Shield 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.
