Non-rectangular shield takes the heat

The Chomerics Division of Parker Hannifin Corporation is launching Soft- Shield 3800, an electrically conductive fabric-over-silicone foam EMI shielding and electrical grounding gasket for low closure force and high temperature electronics applications. Claimed to be the first product of its type to reach market, profiles come in complex and unique non-rectangular shapes.

The product offers 100dB shielding effectiveness in the range 20MHz to 10GHz. Applications include computer server faceplates and inserts, consumer electronics, electronics enclosures, door seals and EMI window/vent gaskets. With an operating temperature range up to 125°C, the products suit applications exposed to high heat, supported by UL 94 V-0 flammability rating.

Chomerics Division’s global market manager, Ben Nudelman, said: “This product typically requires less than 80g/mm of closure force for effective electrical contact. It also takes less than 10 per cent compression set, delivering reliable and repeatable shielding performance over the service life of the device.”
