5 Shield description
The shield is made of soft ferromagnetic material with a high µr value, this attracts and concentrates the
magnetic flux. In order to get a low hysteresis the shields are annealed after shaping. Any applied mechanical
stress will deteriorate the performance and should be avoided. The purpose of the shield is to concentrate the
wanted signal and to reduce the influence of stray fields. Our shield is usable for busbar and PCB
applications.
