    MCL61, LF Magnetic Shielding Film, Width: 61cm

    MCL61 is a novel magnetic shielding film made from an amorphous cobalt alloy for the shielding of low-frequency alternating magnetic fields.
    Please note: Permanent magnets (magnetic DC fields) are not shielded!
    Because it is a metallic product if used in terms of surface area and if it is grounded accordingly it also shields low-frequency electric alternating fields (LF) and high-frequency fields (HF).
    In comparison with MUMETALL® our new MCL61 has many advantages:
    MUMETALL® is soft and sensitive, on bending, to shocks and on processing it looses the attenuation very fast. The cobalt strips in our MCL61 are flexible but hard even at small bending radii. The attenuation remains constant even at high mechanical stress. Because the cobalt strips are only 20 µm thin, 50 mm width and sharp like a knife, we laminate it for protection. Due to the lamination MCL61 is corrosion-resistant even in humid environments.
    With a width of 61 cm big areas are shielded fast. MCL61 can easily be cut with scissors.
    You can order from 1 running metre in steps of 0.1 running meters! Max. length at a stretch is 20m.
    This product is cut off according to your specifications, a return is not possible!
    The above mentioned price refers to a length of 1 metre.
    Technical data:
    • Width: 61 cm
    • Length: By the meter / 20 m rolls; Because of the high production costs, we allow to divide up the ordered quantity!
    • Attenuation LF magnetic field: 30 dB (97 %); the attenuation depends on the number of phases, cable twisting, the size of the area, etc.; work in large areas: shield cables with 1-2 sheets, fuse-boxes with 2-4 sheets;
    • Attenuation HF: 40 dB at 1 GHz
    • Weight: 265 g/m²
    • Material thickness: 0.1 mm
    • Color: Silver
    • Permeability: µ 4 = 25,000; µ max. = 100,000
    • Saturation polarization: 0.55 T
    • Materials: Polyester, Co69, Fe4, Mo4, Nb1, Si16, B7
    Warning: The cutting edges are sharp like a knife!
    Important: Its difficult to glue the film free of creases, best cover the area with solid wall coverings.
    Wall, ceiling, floor: Best use a high-viscous assembly adhesive, that adheres to non-absorbent substrates. Smooth the glue, lay up the film, smooth with a pressure roller or squeegee. The sheets of MCL61 should be overlapped, level out the overlappings, paint it over with any commercial synthetic dispersion paint. Please pay attention that the film is a steam barrier on wall surfaces!
    MCL61 is electrically insulated. To ground it, every strip has to be screwed with a chopper disk, that penetrates the polyester film. The grounding set MCL contains all for 10-20 strips.
    Shielding attenuation:
    The shielding attenuations are regularly tested in the manufactuer's own lab, HF due to ASTM D4935-10, the LF magnetic field due to ASTM A698/A698M-07.
