Twinax Connector Dimensions
Twinaxial Connector: A Twinax connector is a 50 ohm threaded connector, similar to a Coax Connector. The main application of Twinax
connectors is on components for RF systems. [Twin-axial].
A Bulk-Head or Chassis Mount style Twinax Connector is shown in the graphic. Note the dimensions for the chassis mounting hole is also provided. Also that only one side of the connector is a cable interface, the opposite end is a solder cup connection.
Of course Twinax connectors come in a variety of styles: Wallplate Mount [Panel Mount]; Female To Female, T connector Female / Female / Female, and 100 Ohm, Twinax Terminator to name just a few.
The Twinax connector or Twinax cable is comprised of two inner conductors which normally carries the signals surrounded by an outer conductor [normally ground]. A Twinax Cable/Connector is used with a differential signaling circuits and normally used with 78 ohm or 95 ohm twin conductor cables [Twinax cables].
One of the interface buses that could use a Twinax connector is the MIL-STD-1553 bus. In addition there are also a number of interface buses to only specify the electrical interface with out regard to the mechanical interface, or connector. So there are a number of other differential standards a Twinax connector could be used on. Because a Twinax coax connector uses two axial leads surrounded by a shielded conductor a twinax connector could be used with a number of differential cable interfaces.
A similar connector that only uses one conductor surrounded by a cable shield could be either a BNC Connector or
SMA Connector. In all most all cases the cable shield is grounded when used with a BNC or SMA connector.
