8D Series
Twinax & Quadrax Contacts

Contacts for Full Duplex Ethernet Link
Twinax and Quadrax contacts with robust MIL-DTL-38999 compliant
screw coupling system for networks and high vibration environments.
High speed

One quadrax contact = 2 twinax contacts.
Data rate up to 1 Gbit/sec.

=A wide range available

Compatible with all SOURIAU standard 38999
shells, plating and inserts with #8 cavities.
Same cavity for coax, concentric twinax (=triax),
power, and ELIO® fiber optic contacts.

A flexible range

Quadrax contact available in 100 & 150 ohms
(grounded or not).
Mix Twinax and Quadrax in the same layout.
