What about using coax contacts ?
Ethernet twisted pairs carry a symmetrical (balanced) signal. Once terminated into a coax contact, the inner core will be protected by a shield -
but not the outer contact. Because of EMI issues, the signal will no longer be balanced. Conclusion - it does not work and is not recommended.
Conclusion
To carry 100Mb/s data signal, 100BaseTX or Fast Ethernet recommends the use of Cat5e connectors as well as Cat5e cable with the support
of a 100MHz signal. Nevertheless, a 100Mb/s signal can be transmitted in certain conditions (short distance, only one connector, lower
frequency but a different code) thru many other connection materials - not necessarily Cat5e rated.
What about using Quadrax contacts ?
The Quadrax contact is used in railway applications because of the use of quad cable. In this specifi c market, the standard Ethernet twisted
pairs wires cannot be offered, they are too thin and often solid (not stranded).
In the rest of industry, UTP (Unshielded Twisted Pairs) cables are widely used. The Quadrax contact is not designed to terminate them. And
thus, are not advised for industrial applications.

Note: Shielding can be replaced by
DC power.
