Desuper Panel Mount Aviation Connector Plug 16mm Dia Screw GX16 8 Pin

These are quality cable-sockets and panel-mount plugs ( i.e pins facing you).... As you can see the pins are exposed- so only for low-voltages. The current-rating is not specified reliably IMHO.... but look to be a few amps. There will be a limit to the total-current per connector, due to multiple heating effects, but unless you want lots you'll just have to try it. There is also a 4-way version, which look like the same family / Manufacture. There is a polarising feature to prevent mis-alignment, unless you are VERY heavy-handed.
