ARRANGEMENTS • 40 to 160 signal contacts • Differential pairs arrangement available

BRUSH CONTACT Multiple contact interfaces • Strands of high tensile wire are bundled together to form brush-like contacts • By intermeshing two multi-strand wire bundles, an electrical connection is made Redundant current paths: 14-70 (points of contact) per mated contact with a gas tight junction Smooth interface: low friction

MATERIALS • Hood: copper alloy • Wire: beryllium copper

PLATING • Brush wire: gold over nickel • Brush hood: gold or tin-lead or pure tin (RoHS)

• Sleeves: passivated stainless steel • Plastic insert: Liquid crystal polymer, 30% glass filled
