The laminated U-shield is a soft ferromagnetic shield 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 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 LU-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. Thanks to its laminated design it is suitable for high-speed applications.
