Smiths Interconnect’s next-generation split-pair quadrax contacts provide robust, high-speed performance compatible with existing qualified rugged D-Sub connectors. Although existing twinax contacts can support data rates above 10Gb/s, this performance is typically achieved at the cost of signal density in the architecture. The Smiths solution isolates the individual pairs within the quadrax format in existing, space-qualified interconnect systems, and the resulting isolated pair contact supports high-density data rates exceeding 10Gb/s. The new Rugged D-Sub connectors with split-pair quadrax contacts support all mechanical and environmental performance parameters with enhanced electrical signal integrity and meet the high-speed application requirements of the space and mil/aero markets, including the ability to reliably transmit and receive 10Gb/s and beyond with a stable characteristic impedance of 100Ω and compliance with all MIL-STD-202 requirements for shock and vibration.

Materion’s advanced copper beryllium (CuBe) alloys offer a unique combination of strength, conductivity, hardness, and corrosion resistance, and are also non-magnetic and non-sparking, which makes them ideal for use in demanding, harsh-environment applications including undersea and marine communications components, electronic springs and connectors, computer burn-in and test sockets, automotive connectors and wiring harnesses, oil and gas downhole drilling tools, aerospace bushings, and plastic molds and tooling. Materion manufactures CuBe rod, bar, wire, tube, plate, strip, forgings, and extrusions in several distinct compositions to meet specific property requirements, and recommends CuBe wire for Ethernet connector products and cable assemblies. The benefits of CuBe alloys are many, and include improved performance, durability, and reliability over other materials. CuBe alloys offer the highest strength of all copper-based alloys (up to 1,400MPa or 200,000psi); high conductivity, which maintains the flow of electrical and thermal energy; improved miniaturization capabilities, which enables smaller connectors and components with easy formability and the ability to achieve complex shapes and deliver high repetitive cycle lives; excellent stress relaxation, which retains contact forces at elevated temperatures for high-reliability performance; and high durability, which allows the material to resist wear, corrosion, and galling better than most other copper alloys. Microelectronics made with CuBe alloys are also more energy efficient, which helps to conserve natural resources and extend product life. Materion’s selection of high-connectivity CuBe alloys include Alloys 3, 10, 10X, and 310; high-strength CuBe alloys include Alloys 25, M25, 165, 190, and 290; high-connectivity and high-strength alloys include Alloys 390 and 390E; and advanced electronic connector alloys include Alloys 174 and Brush 60.
