Copper beryllium fingerstock gaskets ease EMI problems

25 August 2004 Circuit & System Protection

For minimising electromagnetic interference (EMI) problems where enclosure doors, cabinets and boxes are concerned, Laird Technologies can supply copper beryllium fingerstock gaskets. These act as conductive seals, stopping such emissions from reaching the sensitive equipment within, or leaking out to similarly affect equipment located outside.

The company's fingerstock gaskets offer exceptional shielding for a seal. Moreover, these products are superior whether used in a wiping action or in compression - the elastic nature of the copper beryllium metal alloy means it has a repeatable cycle that is ideally suited for door closure. Compression and deflection performances are superior, even at high temperatures.

Laird Technologies' copper beryllium fingerstock gaskets provide attenuation of 124 dB at 10 MHz. Self-adhesive or clip mounting versions are available to suit specific applications, and the standard finishes are bright copper or tin. A wide range of profiles is available.

Additionally, available from the company are similar fingerstock gaskets in stainless steel (also phosphor bronze) for applications where corrosion might be a problem or where high cleanliness is required - such as in the food, beverage or pharmaceuticals industries.
