Magnetic shielding sheets that are thin and flexible with a high permeability
The Mu-ferro shielding foil is a magnetic shielding sheet and made of a high permability material laminated on a PET film. The sheets are easy to handle and because of the thinness of 0.12 mm the material is very flexible.
The mu-ferro shielding foil is lightweight and has a superior magnetic shielding effect. The best shielding frequency can be made when the frequency gets below several 100 kHz.
When one layer of Mu-ferro foil is used it can shield 100 μT. When multiple layers of the material are used it can shield a strong magnetic field.
Having small deterioration in shielding effect by bending, cutting and punching, Mu-ferro foil can be applied on curved surface and cut or punched in various shapes.
The foil is also available in a long sheet and is suitable for large-scale magnetic shielding for example a shielded room.
