Grounding Braid
More flexible than wire and ribbon, this braid is suitable for use in tight spaces. It provides low electrical resistance equivalent to the wire gauge listed.
Braid with eyelets can be cut to length and mounted without terminating, so its good for applications that require the braid to be looped from ground point to ground point with no breaks.

Grounding Ribbon
The smooth, flat design provides more surface area contact than wire or braid.
EMI-Reducing Grounding Ribbon

Low resistance at radio frequencies reduces electromagnetic interference (EMI). The smooth, flat design provides more surface area contact than wire or braid. Polyester insulation prevents shorting. Use in circuit board applications and other tight spaces.

Grounding Rods
Connect an electrical system to a ground. These copper-plated steel rods provide high levels of conductivity and good corrosion resistance. They are tapered at one end for easy driving. All meet UL 467 for direct burial.
Threaded rods provide the best connection when joining two rods with a connector.
Connectors are high-strength, corrosion-resistant, and highly conductive. They make permanent connections between two rods. One end is chamfered and the other is tapered for easy driving.
Driving heads protect rod ends from "mushrooming" when driven into the ground.

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.
Sheets work well between two flat surfaces.
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.
P-shaped gaskets fit around doors and corners. Attach them with the nonconductive adhesive or add bolts or screws through the flange for extra security.
Urethane foam gaskets block EMI and RFI in most applications. Adhesive-back gaskets are wrapped with conductive aluminum foil and stick on with a conductive adhesive. Plain-back gaskets are made with conductive silver wire.
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.
Silicone rubber sheets are embedded with conductive nickel wire. They block the most interference of our shielding gaskets and also seal out moisture. One side is smooth; the other is rough to help adhesives stick. They meet AMS, ASTM, and military standards for materials.
Beryllium copper gaskets withstand repeated compression and decompression over time, so they’re often used with doors that regularly open and close. They’re also known as fingerstock gaskets. Adhesive-back gaskets stick to flat surfaces. Install clip-on gaskets onto surfaces such as circuit board edges or enclosure door frames.
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. Gaskets that meet UL 94 V-0 self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.

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.
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. Meeting UL 94 V-0, they self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.
Silicone gaskets are good for high temperature and wet environments because they seal out moisture. Most are sized to fit specific mil. spec. connector shell sizes.
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.
