I am making a PCB using Eagle which features a few BNC connectors. Eagle comes with the RADIALL R141426161 component so I'll just use these instead of searching for other ones.

The component has the following schematic symbol and footprint

enter image description here

I see there are 5 pins on the footprint but only 2 on the schematic symbol. I assume one of the schematic pins corresponds to the central pin (signal?) on the footprint and the other to the 4 outer pins (ground?). Can someone clarify for me?

You are right, the outer pins connect to the connector body, which is normally grounded. The intended connector would look something like this:

Though I have to say that straight BNC connectors are not so common.

  • \$\begingroup\$ It looks like it would, but you can confirm that when you import your design to the PCB editor. \$\endgroup\$
