High speed Quadrax contacts consist of an outer contact with four inner contacts spaced in two 100 or 150 Ohm controlled impedance differential pairs. Both contacts, when used in Amphenol MIL DTL-38999 Series III and ARINC type connectors, provide an excellent alternative for harsh environment applications such as:

Ethernet 100 Base-T-100 Ohm
Gigabit Ethernet 1000 Base-T-100 Ohm, 1000 Base-CX, 150 Ohm
Fibre Channel-150 Ohm, 1G/2G
IEEE1394B FireWire-110 Ohm
Serial FPDP Applications, 2.5Gbps
SCSCI-2, 3.2Gbps

Differential Twinax and Quadrax contact options include:

Quadrax Power Contacts
Crimp or printed circuit board termination
Established designs to accommodate a variety of cable types and gauges
Incorporation of Quadrax contacts into ground plane connectors

Ground Plane connectors have conductive inserts that ground the outer conductor of the contact to the shell of the connector. They accommodate size 8 and 12 shielded contacts, of which the size 8 can be a Quadrax type.
