Tri-Start – specials
quadrax and differential twinax contacts
SIZE 8 HIGH SPEED QUADRAX AND DIFFERENTIAL TWINAX
CONTACTS FOR USE IN MIL-DTL-38999 CONNECTORS
Quadrax Contacts consist of an outer contact with four strategically
spaced inner contacts forming two 100 or 150 Ohm matched impedance
differential pairs.
Differential Twinax Contacts consist of an outer contact with two inner
contacts spaced to form one 100 or 150 Ohm matched impedance
differential pair.
Both contacts can be used in connectors for Ethernet 100 Base-T-100
Ohm, Fibre-Channel-150 Ohm and IEEE 1394B FireWire-110 Ohm
applications.
TYPICAL ELECTRICAL PERFORMANCE
• Bandwidth: Up to 3 Gigahertz
• Data rate: Exceeding 2 Gbits/sec.
• Voltage rating: 500 Vrms max. @ sea level
• Dielectric withstanding voltage:
1000 VACrms between all inner contacts @ sea level
500 VACrms between inner and outer contacts @ sea level
Quadrax contacts are also available in ARINC 600 Rectangular connectors. See photo
on right; consult Amphenol Aerospace for further information.
Also available are Quadrax and Twinax Transition Adapters which provide a method of
launching from the high speed connectors to PCB boards.
Consult Amphenol Aerospace, Sidney NY for ordering information for MIL-DTL-38999
