Oriented Wire

TE Connectivity's (TE) Kemtron Oriented Wire is a flat sheet material designed for shielding against radio frequency interference (RFI), electromagnetic interference (EMI), and electromagnetic pulse (EMP). Each sheet contains thousands of embedded thin monel or aluminum wires that are perpendicular to the surface. The wires are chemically bonded to silicone or fluorosilicone and crimped to form a slight zigzag, so they do not drastically affect the compression forces required to make a seal. The elastomer provides the environmental sealing component, while the wires offer electrical grounding and shielding. Under the recommended 15% to 20% compression, the wires bite into the mating surface and penetrate through thin oxide layers, providing low contact resistance.
