Product Description

The UCR3.5 is a soft ferromagnetic shield featuring superior material characteristics such as high linearity and very low hysteresis. The shield is designed for PCB based planar current sensing in combination with a magnetic field sensor, i.e., Hall sensor, AMR sensor and a current conductor.

The UCR3.5 shields 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).
