  • Product Description

    ROUNDIT® EMI C27 XWS is a wrap-around sleeving designed for EMI shielding of wire and cable bundles. ROUNDIT EMI C27 XWS is manufactured from PPS monofilaments and nickel plated copper C27 supplied with an internal layer of PTFE tape thus allowing wire harnesses to be protected from the metal.

    The self-wrapping feature of ROUNDIT EMI C27 XWS 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.

    As an additional benefit, ROUNDIT EMI C27 XWS enables users to stock a limited range of sizes to cover a wide range of cable and wire diameters.

    Thanks to its unique geometry and metal insertion, ROUNDIT EMI C27 XWS is easy to clamp with existing solutions.

    ROUNDIT EMI C27 XWS has many applications in the aeronautical and defense industries.
