High-Speed Differential Twinax

Differential Twinax contacts consist of an outer contact with two inner contacts spaced to form one 100 or 150 Ohm controlled impedance differential pair.

Quadrax contacts consist of an outer contact with four inner contacts spaced to form two 100 or 150 Ohm controlled impedance differential pair.

Differential Twinax and Quadrax contacts provide high data transfer rates, low power consumption, and excellent EMI compatibility.

Both contacts, when used in Amphenol MIL-DTL-38999 Series III and ARINC type connectors, provide an excellent alternative for harsh environment applications requiring Ethernet 100 Base-T, Fibre Channel and IEEE1394B FireWire signal carrying capability.

Typical electrical performance parameters include

• Bandwidths up to 3 Gighertz
• Data rates exceeding 2 Gbits/second
• Voltages up to 500 Vrms at sea level
• Dielectric withstanding voltages up to 1000 VAC rms between all inner contacts at sea level and up to 500 VAC rms between inner and outer contacts at sea level

Differential Twinax and Quadrax contact options include

• Crimp or printed circuit board termination
• Established designs to accommodate a variety of cable types and gages
