    Core Pins

    Mold plastic around these pins to form small holes, or use them to perforate parts. They have a flat head to fit into a counterbored hole. Pins can be machined to fit your application. They're precision-ground to tight tolerances.

    EMI-Shielding Flexible Plastic (MPT) Conduit and Fittings

    Image of System. Front orientation. Conduit and Fittings. EMI-Shielding Flexible Plastic (MPT) Conduit and Fittings.
    A braided copper cover defends against electromagnetic interference (EMI) that can distort or disrupt signals. Install shielded MPT in areas where motors, generators, and other equipment that emit EMI are running. It has a corrugated nylon core that flexes to make tight bends and is typically used indoors. Pair conduit with nickel-plated brass connectors for a fully shielded run.

    Interference-Shielding Expandable Wire Sleeving

    Protect wire and cable from signal distortion caused by nearby equipment and devices. Expandable, this sleeving stretches to fit over items for easy installation, then tightens around its contents for a secure fit. The braided construction permits heat and moisture to dissipate. This sleeving is also used to insulate and organize wire and cable. Cut to size with sheet metal snips.
    Aramid Fabric with Tin-Plated Copper Shield
    Image of Product. Front orientation. Wire Sleeving. Interference-Shielding Expandable Wire Sleeving, Aramid Fabric with Tin-Plated Copper Shield.
    Aramid fabric sleeving combines the benefits of copper and aluminum sleeving. It’s shielded with copper foil to resist high amounts of signal interference, while the aramid fabric weighs half as much and reflects more heat than copper alone.

    Interference-Shielding Tape Wire Sleeving

    Image of ProductInUse. Front orientation. Wire Sleeving. Interference-Shielding Tape Wire Sleeving.
    With a copper and nickel exterior and conductive lining, this sleeving shields your wire and cable from signal interference. Use it near equipment that creates signal distortion, such as transformers, generators, and motors. It’s made of polyester taffeta cloth, so it’s light and flexible. Plus, its coating resists corrosion.
    You can wrap this sleeving like tape around wire and cable while they’re installed, so it’s great for emergency patches. When wrapping, make sure it overlaps itself by half its width. This ensures 98% shielding coverage to keep your components protected.
