Magnetic Shield Corporation

We offer several magnetic shielding products used in electricalelectronic wiring applications such as: power feeds, aerospace, vehicle controls, test and measurement devices, audio-level interconnections, communication equipment, and hand-held devices. Shielding: To provide effective magnetic shielding for cable and conductors such as twisted pair; and avoid pickup of external fields or radiation of interfering, unwanted fields use AA CABLE SHIELD® and SPIRA-SHIELD Flexible Conduit. Cable: Our INTER-8® Weave Cable replaces and provides substantial improvement over conventional twisted-pair cables. INTER-8® Weave Cable consists of four separate conductors braided into interlocking loops and is a field-proven design of Magnetic Shield Corporation. Wire: We also offer our Co-NETIC® AA Wire, which is used in fabrication of magnetic shielding braided sleeving to certain customer specifications where our stock AA CABLE SHIELD® may not be specified.

We offer a wide range of 5-sided magnetic shielding MuMETAL® Cans stamped or formed in either ROUND or RECTANGULAR shapes, and deep-drawn up to a 3:1 depth ratio when necessary. Our standard stock range and custom sizes are available in thicknesses from 0.014’’ to 0.062’’ [0, 36mm to 1, 57mm thick] and made from various MuMETAL®, Co-NETIC® or NETIC® shielding alloys depending on your exact shielding requirements. Typically, our high permeability (µ) 80% nickel-iron MuMETAL® cans are shipped as is since our AA Perfection Annealing method provides a bright nickel appearance after anneal. We do offer other finishes including plating, electro-polish, powder coating

NETIC® is a proprietary brand that is often applied in fields of high intensity (strong fields) because of its high magnetic saturation characteristics. We stock three different types: NETIC® S3-6 is an Uncoated, high iron shielding alloy, and is prone to oxidation. Typically this alloy is painted or plated after shield fabrication. NETIC® S3-6 ET is Electro-Tin Plated and can be used as is. Both products are available as Sheet or Foil, and contain the same chemical composition and shielding efficiency. NETIC® S3-6 PST is our high iron shielding alloy with added Pressure Sensitive Tape. For ultimate performance, NETIC® is commonly used in combination (in layers) with Co-NETIC® or MuMETAL®. If used in combination, the NETIC® layer is placed closest to the source of interference, with Co-NETIC® or MuMETAL® layer closest to the component being shielded. Used for either fabricated or flat shields, it may be re-annealed for better performance.

Hands-On" evaluation and sampling begins here. Using our Lab Kits, Meters & Probes, shielding can be prototyped with everyday common hand-tools, or bench- top and model-shop equipment. Layers of material from a Lab Kit can be added until the unwanted field is reduced (attenuated) to the desired level. Your prototype then serves as a production model. After prototyping, contact Magnetic Shield Corporation for a fabrication or stock material quotation. Our Lab Kits include a variety of MuMETAL®, Co-NETIC®, and NETIC® alloy samples for testing and evaluation. Three Lab Kit options are available.

One of our most popular research products, fabricated from MuMETAL® alloy is the Magnetic Shield Corporation Zero Gauss Chamber. These scientifically engineered chambers provide a laboratory work space of extremely low magnetic field for testing and experimentation. MuMETAL® Zero Gauss Chambers have been used worldwide by many universities, private research companies, national laboratories and companies required to provide evidence of military or consumer regulatory compliance. Our chambers are preferred because they are made from high permeability (µ) Stress Annealed MuMETAL®, which provides a consistent, low field test area. Our standard Zero Gauss Chambers consist of 3-layers and are designed

Magnetic Shield Corporation supplies custom tape-wound MuMETAL® Toroidal Cores to industries requiring High Metering Accuracy (HMA) current transformer cores. By using our proprietary brand of MuMETAL® and properly heat treating in a controlled hydrogen atmosphere furnace, (to a soft magnetic anneal) we maintain close control of the magnetic properties over a broad range of flux densities which permits the most economical and efficient design of your transformer. We offer a range of custom wound cores from minimum 1” [25mm] inside diameter to maximum 47.25” [1200mm] outside diameter, using MuMETAL® foil thicknesses ranging between 0.004” [0, 1mm] and 0.014”
