Amphenol Quadrax Contacts Specifications

By keeping a large inventory of Quadrax contacts and building your connectors to order, we can offer our customers the flexibility of using a wide range of connector/insert combinations. Depending on the application, we can select the correct connector, the right Quadrax contacts, and deliver a kit within 24 hours.

PEI-Genesis’ large inventory of Quadrax contacts is especially important when used with the popular MIL-DTL-38999 connector line. PEI-Genesis has the largest Quadrax inventory in the world - and we build the Quadrax Groundplane Connectors from stock so we can ship you a complete system. In Comparison, most distributors require long lead times and impose mandatory minimum purchase quantities for Quadrax contacts and connectors.

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

• 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
