A current-carrying twisted pair is superior to parallel conductors, but is of limited effectiveness in reducing electromagnetic radiation. Correspondingly, the twisted pair is limited in avoiding unwanted pickup of external H-fields (D.C. to 100 KHz).
Inter-8® Weave Cable substantially reduces magnetic field pickup and radiation compared with conventional twisted pair cable. Our cable involves four separate conductors braided into interlocking loops and is a patented design of Magnetic Shield Corporation. In application, adjacent conductors 90º apart are connected together, effectively providing a two conductor circuit.
Because the Inter-8® Weave Cable design incorporates parallel conductors, the cable provides double the current carrying capacity of a two wire cable of the same AWG size. In contrast to conventional twisted pair, INTER-8 WEAVE does not kink or untwist when left free.

Inter-8® Weave Cable has applications to many interference problems. Current-carrying conductors generating interference fields can be replaced with INTER-8 WEAVE cable to substantially reduce radiation. In low impedance circuits where external interference results in disturbing signals, Inter-8® Weave Cable will reduce the circuit sensitivity to the external fields. Among typical applications are cable connections to strain gages, thermocouples, photoelectric detectors, audio coils and transformers, piezoelectric transducers and preamplifiers.
SPIRA-SHIELD is flexible conduit that provides high permeability magnetic shielding for sensitive cables and conductors. Constructed of .010" thick CO-NETIC AA Alloy, SPIRA-SHIELD provides greater attenuation than braided sleeving and also furnishes physical protection. Among typical applications are ground support and communication equipment, shipboard control systems, audio-level interconnections, sensitive instrumentation and aerospace apparatus.
Co-Netic® Braided Sleeving, constructed of 36 or 34 AWG CO-NETIC AA high permeability wire, provides superior flexibility compared to foil that is spiral or channel wrapped around cable.
CO-NETIC AA wire in .005" diameter is widely used in magnetic shielding braid applied over cables. All gauges have applications where high permeability, low coercive force and ferromagnetic properties are required. CO-NETIC AA wire is corrosion resistant and has an affinity for solder. Meets MIL-N-14411, Composition I.

Magnetic Shield Corp.'s Lab Kits are highly effective in solving design problems of magnetic interference. (D.C. to 100 kilohertz). By adding MU METAL, CO-NETIC and NETIC layers until desired attenuation is achieved, minimum material requirements can be determined. This results in significant cost savings in the final design.
An important advantage of the "hands-on" shielding approach is that changes in a circuit layout, shield configuration, power levels and component orientation are easily evaluated. The Lab Kit permits magnetic shields to be designed and modified until required performance is obtained. The prototype then serves as a model for production.
As a special offer to introduce you to the exceptional characteristics of our CONETIC and NETIC proprietary alloys, Magnetic Shield has assembled the LK110-IS Lab Kit with Gaussmeter. Containing all the same wide variety of CONECTIC and NETIC alloys as both the LK-120 and LK-110 Lab Kits, the Internet Special Lab Kit also contains a Gaussmeter, This combination of materials and meter is offered for a reduced cost of $199.95.
The EF-401 Gaussmeter is a cost effective, handheld, single-axis magnetic field meter that provides the user with a quick, reliable and easy way to measure electromagnetic field (EMF) radiation levels.
Purchase an LK-110-IS and save 10 per cent off the retail price of the Kit and the Gaussmeter.

MU METAL® offers important electromagnetic field shielding characteristics, including very high magnetic permeability - its ability to absorb magnetic energy. The unique properties of this family of alloys results in the highest possible attenuation, making these shielding alloys the materials of choice for reducing low-frequency electromagnetic interference (EMI).
MU METAL® is a trademarked brand of Magnetic Shield Corporation. MU METAL® meets MILSPEC 14411C, composition 1. When the specification or the application calls for a magnetically soft or high permeability material, MU METAL® can frequently be successfully applied.
MU METAL® magnetic shielding prevents magnetic fields from reaching areas where they would cause magnetic interference. Magnetic shielding is used around either the source of interference, to prevent electromagnetic radiation from leaving a device; or more typically, around a sensitive device, to prevent the electro magnetic interference (EMI) from disrupting normal operations.
