    EMI/RFI Shielding Gaskets

    These gaskets absorb electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent inaccurate signals, flickering displays, and other electrical problems. They compress to fill gaps and complete a grounding path around doors and access panels.

    Polyurethane Foam

    Sheets work well between two flat surfaces.
    Urethane Foam—Urethane foam gaskets block EMI and RFI in most applications. Gaskets are made with conductive silver wire.
    Polyurethane Foam—Polyurethane foam gaskets are covered with either a conductive nickel/copper braided fabric or conductive aluminum foil. A nonconductive adhesive holds them in place. To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. Cut these gaskets to length with scissors.
    Adhesive Backing—Adhesive-back gaskets stick to flat surfaces.
    UL 94 HF-1—Gaskets that meet UL 94 HF-1 stop burning within two seconds if they catch on fire and won’t spread the fire by dripping.
    UL 94 V-0—Gaskets that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.

    Half Round
    Image of Product. Front orientation. EMI/RFI Shielding Gaskets. Half Round.
    Half-round gaskets work well in grooves. Use a gasket slightly thicker than the depth of the groove; it will compress to fill the gap.
    Polyurethane Foam—Polyurethane foam gaskets are covered with either a conductive nickel/copper braided fabric or conductive aluminum foil. A nonconductive adhesive holds them in place. To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. Cut these gaskets to length with scissors.

To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. Cut these gaskets to length with scissors.
    Adhesive Backing—Adhesive-back gaskets stick to flat surfaces.

    EMI/RFI Shielding Gaskets for Data Connectors

    Fit these gaskets over connectors that plug in to your enclosure to absorb interference and prevent signal problems. They block electromagnetic interference (EMI) and radio frequency interference (RFI), which cause flickering displays and inaccurate readings.
    Computer Connector
    Image of ProductInUse. Front orientation. EMI/RFI Shielding Gaskets. EMI/RFI Shielding Gaskets for Data Connectors, Computer Connector.
    Polyurethane Foam—Polyurethane foam gaskets compress for a tight fit between plugs and receptacles, and their conductive nickel/copper braid creates a continuous shield and grounding path.
    UL 94 V-0—Gaskets that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.
    Interference Reduction @ Frequency—Interference reduction at frequency, also known as attenuation, describes how much EMI and RFI is blocked. These gaskets block most interference; use them for general purpose shielding as well as protecting sensitive or precision components.
