Decent DC power connectors that aren't barrel or powerpoles?

MosherIV:
Have you looked at round DIN connectors?

They are rated upto 2A on each pin.

Yes, you can use D Types but check the current rating of the pins, they tend to be limited. You can use multiples pins on same volt to share the current load.

Avoid using common ones to stop people 'trying them out to see what happens'

Thanks all again.

I looked at DIN a well. In fact I have a whole box of 2 pin DIN connectors (plugs and sockets) but they are terribly unreliable unless you spend spend spend.
nali:
How about speaker connectors e.g. Neutrik? A little bit more expensive but robust, rated for tons of current and uncommon enough that they [probably] won't get plugged into anything else.

CJay:
As Nali said, Neutriks are good but not cheap.

Molex are good, it'd be worth having a look at commercial radios to see which ones to use and which to avoid as some of those series are used for features like external ATU or CAT control, it'd be an expensive mistake to plug the wrong one in if you bumped into a radio that uses them.

Maybe use the old style hard disk/5.25" floppy connector?

FWIW, Tait and (I think) Kenwood use the same Molex for power as Icom use for ATUs, not a great combo if you're plugging stuff in 'blind' under a shelf etc.


Curious if you used genuine Anderson powerpoles or knock offs as I've not run into problems with bad contacts (yet) on either?

Amass makes latching versions....



but even the standard unlatched type fit together very snugly, after all they are used in relatively high vibration models etc.  I use XT60 for test leads, love the things, XT60-banana, XT60-alligator, XT60-testhook, XT60-wire, XT60-2xXT60 (parallel), XT60-XT60-XT60 (series), XT60-USB, XT60-Barrel, XT60M-XT60M, XT60F-XT60F.... and so on, so I can just plug together the ends to make up the right cable as needed.  The connectors are even marked with a small embossed +/- so you can always be sure you're following the same "standard".
