Systems Protection’s Electromagnetic Interference (EMI) product line was designed to provide shielding protection for a range of temperatures and applications.  Constructed from conductive metallic materials including nickel-plated copper, tin-plated copper, and stainless steel, these sleeves provide excellent shielding properties with the added benefit of abrasion or thermal protection based on additional layers of Nomex®, PPS or polyester.  Unlike commonly used metal braids, the woven structure of our wrappable EMI protection products remains stable, guaranteeing the same level of EMI shielding regardless of the installation diameter within the recommended application range.  Various levels of shielding performance are offered, from 95% coverage to optimized designs balancing weight and metal content.   

EMI can cause adverse effects on electronic components and equipment leading to operational malfunctions. Proper shielding and grounding of electromagnetic sensitive components can effectively eliminate this occurrence.

Product Spotlight: ROUNDIT® EMI FMJ


ROUNDIT® EMI FMJ (Full Metal Jacket) is a wrap-around sleeving designed for high performance EMI shielding of wire and cable bundles. ROUNDIT EMI FMJ is manufactured from PPS monofilaments and nickel plated copper.

The self-wrapping feature of ROUNDIT EMI FMJ allows for quick and easy installation and removal of the product for assembly and maintenance.

The design offers innovative solutions to the protection of breakout areas and also provides ease of removal when inspection or maintenance of cables is necessary. The stable construction guarantees the same level of EMI shielding regardless of the diameter on which it is installed within the recommended application range.

Thanks to its unique geometry and metal insertion, ROUNDIT EMI FMJ is easy to clamp with existing solutions.
