High Speed Contacts

High Speed Quadrax andDifferential Twinax ContactsAmphenolAerospaceDifferential Twinax and Quadrax contacts providehigh data transfer rates, low power consumption,and excellent EMI capability. They offer controlledimpedance of 100 or 150 Ohm and are ideal foruse in harsh environments.38999III II I SJTAmphenol provides the latest technology in high speed contacts - differentialtwinax and quadrax contacts, size 8, for use in MIL-DTL-38999 Special* CircularConnectors.DIFFERENTIALTWINAX CONTACTSHigh speed Differential Twinax contactsconsist of an outer contact with two innercontacts spaced to form one 100 or 150Ohm controlled impedance differential pair.See pages 380 and 381 for performancedata and ordering of Differential Twinaxcontacts, and consult AmphenolAerospace for more information.QUADRAX CONTACTS• High speed Quadrax contacts consist ofan outer contact with four inner contactsspaced to form two 100 or 150 Ohmcontrolledimpedance differential pair.• Both contacts, when used in AmphenolMIL-DTL-38999 Series III and ARINCtype connectors, provide an excellentalternative for harsh environmentapplications such as:• Ethernet 100 Base-T-100 Ohm• Gigabit Ethernet 1000 Base-T-100 Ohm• Fibre Channel-150 Ohm• IEEE1394B FireWire-110 OhmDifferential Twinax ContactQuadrax ContactDifferential Twinax and Quadrax contact options include:• Crimp or printed circuit board termination• Established designs to accommodate a variety of cable types and gages• Ground plane connectors can incorporate quadrax contacts. Theseconnections have conductive inserts that ground the outer conductor ofthe contact body to the shell of the connector. They accommodate size 8and 12 shielded contacts of which the size 8 can be quadrax type.See pages 377-379 for performance data of Quadrax contacts.
