I'm powering a load that draws 5A at 18V from a brick power supply. The power supply and load are separated by a thin metal wall that has 1/4" (6.35mm) holes in it. So I'm trying to find connectors that can fit through 0.25" diameter holes.
The best I've found is small JST plugs, but they're more like 0.29" so we'd have to file them down to fit through the holes.
I'd appreciate any suggestions, either for a 2-circuit connector or two 1-circuit connectors.
