Description

Magnetic field shielding film MCL61 is our novel magnetic shielding film made from an amorphous cobalt alloy. For shielding of low-frequency alternating magnetic fields.  Also shields low-frequency electric alternating fields (LF) and high-frequency fields (HF).

Statical magnetic fields: Other than stated in the headline, this product is not MUMETALL®. We are utilizing a newer alloy which provides a better shielding. MUMETALL® is promoted to shield statical magnetic fields, referred to the usually used foils (material thickness 0.1 mm) the effect of the shielding is quite low indeed. We are using cobalt based alloy, attenuation increases from strength to strength with the velocity of the magnetic fields. There are no velocities by statical magnetic fields or by permanent magnets, that is why this product won´t shield those.

Shielding attenuation

The shielding attenuations are regularly tested in our own laboratory, HF due to ASTM D4935-10, the LF magnetic field due to ASTM A698/A698M-07. You’ll find the test report above.

Technical Specification

  • Width: 61 cm
  • Length: Minimum 1 metres, available by the running meter.
    You can also order this product in increments of 20cm. For example: – 1.2 running meters!
    This product is cut off a large roll according to customer specifications. A return is not possible!/ 20 m roll
  • 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: 70 dB
  • Weight: 265 g/m²; Material thickness: 0.1 mm; Colour: Silver
  • Permeability: µ 2 = 10,000; µ 4 = 25,000; µ max. = 100,000;
  • Saturation polarization Bs: 0.55 T
  • Coercive field strength Hc: 0.5 A/m
  • Remanence Br/Bs: 0.7
  • Curie temperature Tc: 225 °C
  • Materials: Polyester, Co, Fe, Mo, Nb, Si, B

Processing

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 over-lappings, paint it over with any commercial synthetic dispersion paint. Please pay attention that the film is a water vapour barrier on wall areas!

See MCF5 Magnetic field – shielding film. Magnetic field – shielding film to shield LF magnetic fields. Shielding smaller areas, e.g. Electronic applications or for cables. 30 dB attenuation = 97 %

Grounding

MCL61 is electrically isolated. To ground it, every strip has to be screwed with a chopper disk, that penetrates the polyester film. The grounding set GCL contains all parts for 10 strips.

Delivery Time: Usually between 3 – 4 business days

Additional Information

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 faster compared to 15 cm width MUMETALL®-strips. MCL61 can easily be cut with scissors.
