PART NUMBERS

Oriented Wire

AVAILABLE IN SHEET OR STRIP FORM

ElectroMet^TM oriented wire provides multiple options to suit any application

ELECTROMET™ ORIENTED WIRE

ElectroMet oriented wire gaskets are EMI shielding and sealing composites. Monel® or aluminum wires embedded in the elastomer and oriented perpendicular to the mating surfaces provide EMI sealing. Solid or sponge silicone provides the weather sealing. Solid silicone weather seals are recommended for high-pressure applications. Silicone based oriented wire composites are capable of withstanding temperature ranges from -70°F to 500°F (-56°C to 260°C).

Oriented wire materials are available in sheet or strip form with a minimum thickness of 0.032 in (0,8 mm).

SPLICING TECHNIQUES

Oriented wire can be supplied as a one-piece gasket. Gasket sizes are available up to 9 in (228,6 mm) X 36 in (914,4 mm) frame size. Larger gaskets are normally bonded together using a splicing technique. These splicing methods minimize elastomer waste when compared to jointless gasket design. In preparing drawings, designate the splicing method and locations if splices are permitted. Common splicing methods include skive, miter, butt, and dovetail.

DIE-CUT GASKET

Oriented wire can be supplied as a die-cut gasket in various configurations. Gasket sizes are available up to 9 in (228,6 mm) X 36 in (914,4 mm). Several of the most common die-cut gaskets are for cable connectors and Sub-D connectors.

ELECTROMET IMPREGNATED WOVEN WIRE AND EXPANDED METAL

ElectroMet impregnated wire mesh and expanded metal gaskets are available in thin sheet form. EMI shielding is provided by woven aluminum mesh or expanded metals. Pressure sealing is provided by neoprene or silicone elastomer impregnated in the mesh. Fluorosilicone is also available for specific applications that require resistance to oils, hydraulic fluids and hydrocarbon fuels.

MATERIAL SELECTION

Monel⁹ wire is bonded into a silicone elastomer for uniform surface and multiple "spring" effect with each contact point.

Features and Benefits:

• Ideal for both military and commercial applications

• Wide choice of profiles to fit large range of applications

• Custom dies can be built to accommodate specific designs

• Shielding effectiveness up to 120 dB at 10 GHz
