Magnetic Shielding Efficiency for Wiring Applications

August 31, 2015 - "Company News"

Increasingly, many magnetic shielding applications today require a flexible, continuously enclosed shielding barrier to avoid pickup of external fields or radiation of interfering, unwanted fields.  One of the key components to a successful solution is choosing the correct shielding alloy.  Co-NETIC® AA has been used in many demanding applications and is one of the most recognized and specified brands of magnetic shielding alloy worldwide.  Co-NETIC® AA alloy is a proprietary material known for high permeability and used for reducing EMI in electrical / electronic wiring applications such as:  power feeds, aerospace, vehicle controls, test and measurement devices, audio-level interconnections, communication equipment, and hand-held devices.  Co-NETIC® AA CABLE SHIELD® is specified regularly for these types of applications across a broad range of industries as listed below.


AA Cable Shield - Braided Sleeving

AA CABLE SHIELD® here is produced from Co-NETIC® AA high permeability 36AWG Wire and formed into a flexible braided weave sleeving, which is available in tubular continuous lengths.  Our AA CABLE SHIELD unique design with a continuously enclosed shielding barrier manufactured with proprietary Co-NETIC® AA alloy has distinct advantages over foil wrapping or rigid channeling; and is used to avoid pickup of unwanted external H-fields (D.C. to 100 kHz), or to mitigate radiation from cable and conductors.  Co-NETIC® AA is used primarily in low intensity fields where high attenuation is desired (high initial permeability & high shielding efficiency).  Braid is tightly weaved, so shield coverage is 90% at nominal linear state.  In addition, Co-NETIC® AA wire is corrosion resistant. 

Co-NETIC® AA wire in .005" diameter (36AWG) is widely used in fabrication of magnetic shielding braid to certain customer specifications where our stock Co-NETIC® Braided Sleeving may not be specified.


Co-NETIC® Braided Sleeving complies with A-A-59569 (QQ-B-575).  Co-NETIC® Wire meets military specification MIL-N-14411, Comp 1.

Sample:  A sample of the AA CABLE SHIELD® is included in our Lab Kits.

Experimentation and Prototyping

Experimentation, testing, and prototyping typically begins with our "hands-on" Evaluation Kits.  Our kits include several sizes and thicknesses of material to create usable shields.
