Differential Twinax Contacts
General Description
AMPHENOL DIFFERENTIAL TWINAX CONTACTS
Offer several advantages for high data transfer rates, low power
consumption and excellent EMI compatibility:
• Two strategically spaced inner contacts form two 100 or 150 Ohm
matched impedance differential pairs
• Outer contact has rugged wall section for durability
• Available in size 8 crimp termination style
• Also available in size 8 with PC tails
• Requires modification of MIL-DTL-38999 connector to
accommodate keyed contacts
