The size 12 contacts can do 15-25A. There's e.g. the Amphenol size 25 / 24 connection version, with 12 high current contacts and 12 smaller contacts.

There's not too many that have a variety of pin sizes and that are military qualified, though. And it's not cheap stuff, for sure.




Yeah I probably could have explained a bit more, I did find connections that could do it but it was never quite right in terms of a size pin count or cost trade off for this specific project. The standard absolutely has options for higher current but it comes with a smaller pool of available suppliers making those parts and thus they cost more. I wasn’t prepared to spend $50 Australian on a single pair of connectors for this project, especially since due to wiring limitations I’d have probably had to get two pairs.

They firmly entered my mental toolbox as a go to for a flexible circular connector when I don’t need to join existing physical interfaces like Ethernet or higher speed USB where the signal reliability is potentially worth just using a sealed socket with matching circular screw on connector, but for the sort of thing where I’d have made up a DB9 or DB25, I’m definitely going to be reaching for these again in future (I did get a few of them and used the solder cup versions to avoid needing the crimping tools and the associated extra costs)
