• It is typically:
             - Cylindrical boxes that are easy to produce and well suited to the conduction of magnetic field lines.
             - Rectangular Boxes that are a little more expensive than cylindrical shapes but common in many applications.
  • MMc also carries more complex boxes with shapes made to fit the geometry of the part that has to be shielded (toroidal cores for example).


  • The junction box-cover must allow interlocking without forcing the mumetal while minimizing the gap between the two parts.
  • The closure can be without added components (like a shoe box), with screws, with hinges ...
  • MMc will advise you on the dimension of the gap to be implemented, the length of the overlap between the box and the cover...
