| METEX has been a pioneer in EMI/RFI çasketing and shielding products for more than five decades. In fact, METEX developed the very first EMI/RFI gasket to help MIT solve a severe interference problem for the earliest high-power, high-frequency airborne radar. That pioneering spirit is still alive today—with a complete line of military and commercial-grade EMI/RFI shielding solutions. As communications and information technologies expand,the need to provide EMI/RFI solutions becomes more critical than ever before. | |||||||||||||||||||||||
| Metex all metal mesh gasketing is a versatile material used in a wide variety of applications where: • High attenuation is required • Ease of installation or field replacement is required • Extremes in temperature or atmospheric conditions are encountered Metex mesh gaskets have been proven, in aerospace, avionics, automotive and electronics systems, solving the most demanding shielding and sealing problems. Mesh gaskets can be made from any ductile material that can be drawn to form a wire. Wire diameters are typically in a range of .0035" to .011", with other diameters available for specific applications. The most common materials include: • Monel—An alloy of nickel and copper with good electrical performance and excellent corrosion resistance. • Tin-plated, copper-clad steel—SnCuFe is a 1005-1010 steel wire, with a copper outer cladding and a tin-plated exterior. This material has excellent electrical properties and provides EM attenuation over a wide range of frequencies. • Aluminum—Alloy 5056 wire provides good electrical performance, is lightweight and is also useful in applications where galvanic corrosion is a con- | |||||||||||||||||||||||
| • Stainless Steel—Good electrical performance. This material is often used for its mechanical characteristics and corrosion resistance. All-metal mesh gaskets are typically installed using mechanical fasteners, press fit into a groove or return flange on a sheet metal enclosure, or bonded in place using a conductive adhesive. | |||||||||||||||||||||||
