DB-9 connectors are generally good for 5 Amps

I would use the solid machined pins though, and not the stamped formed sheet pins.

There actually are pins for DB connectors that accept both AWG18 and AWG16 wire. They are provided by a certain well known avionics mfgr with certain units....and most shops have piles of them around because we don't end up using many of them. They are long suckers, but they will hold those fat wires. Takes a different crimper (or solder) as well.

There are also DSub connectors made out of various materials and specs to handle various current loads. You can actually get some pretty exotic ones that handle piles of current, other ones with wild shielding, pin sizes, bi-metal, etc..

Any, I'd probably want to know more about the actual widget before I made my choice for sure.....

Cheers,
Stein

The Molex and Faston are two very different options, want to narrow it?
Yep, I see it now - reading is fundamental :-).

I'd still be torn between molex and fastons but for a production widget I'd lean toward a molex connector.

Molex connector.

The ultimate maintenance wise would probably be a Molex connector on the black box with a small pigtail to a terminal strip mounted behind the panel. Easy to pull the box out, measure voltages, and add/modify wiring. Unfortunately, it adds weight and another point of failure. If you want to effortlessly pull / replace the box, you need a multipin connector.

Besides Molex & Amp/Tyco, don't forget Samtec... They have quite a list, although maybe not quite as wide an offering in the 'Board to Cable' category?
