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
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?
