The relays feature an internal mu-metal magnetic screen.
* An internal mu-metal screen to eliminate problems that would otherwise be experienced due to magnetic interaction.
The use of materials with very high permeability (mu-metal is a typical example) provides better shielding performance than eddy current cancellation at low field values in general.
The influence of magnetic fields on sensitive equipment can be reduced by up to several orders of magnitude by passive shielding with soft iron alloys (e.g., Mu-metal, Permalloy, Conetic).
Mu-metal, a special alloy with high permeability at low magnetic flux densities, is a good magnetic shielding material.
An internal mu-metal magnetic screen enables Pickering relays to be stacked closely together without the magnetic field from one relay affecting adjacent parts.
The magnetic shield assembly has a parallelepiped shape encompassing all the cavities, it will be made of sheet metal of a Mu-metal thickness of 2mm.
