High Speed Quadrax and
Differential Twinax Contacts
Amphenol
Aerospace
Differential Twinax and Quadrax contacts provide
high data transfer rates, low power consumption,
and excellent EMI capability. They offer controlled
impedance of 100 or 150 Ohm and are ideal for
use in harsh environments.
Amphenol provides the latest technology in high speed contacts - differential
twinax and quadrax contacts, size 8, for use in MIL-DTL-38999 Special* Circular
Connectors.
DIFFERENTIAL
TWINAX CONTACTS
High speed Differential Twinax contacts
consist of an outer contact with two inner
contacts spaced to form one 100 or 150
Ohm controlled impedance differential pair.
See pages 380 and 381 for performance
data and ordering of Differential Twinax
contacts, and consult Amphenol
Aerospace for more information.
Differential Twinax Contact
QUADRAX CONTACTS
• High speed Quadrax contacts consist of
an outer contact with four inner contacts
spaced to form two 100 or 150 Ohm

controlled
impedance differential pair.
• 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
• Fibre Channel-150 Ohm
• IEEE1394B FireWire-110 Ohm
Quadrax Contact
Differential 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. These
connections have conductive inserts that ground the outer conductor of
the contact body to the shell of the connector. They accommodate size 8
and 12 shielded contacts of which the size 8 can be quadrax type.
See pages 377-379 for performance data of Quadrax contacts. Consult
Amphenol Aerospace for further information needed.
