U-Shape Flux Concentrator

Product Description

The U-Shape is a soft ferromagnetic flux concentrator featuring superior material characteristics such as high linearity and very low hysteresis.

The U-Shape flux concentrator is designed for planar current sensing in combination with a magnetic field sensor, i.e. Hall sensor, AMR sensor and a bus-bar conductor.

The "U" 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.

PML collaborates for current sensor applications with Maglab (representative & development partner) GmbH (For design optimization & simulation) and Melexis GmbH (Qualified automotive sensor supplier).
