Gene, Speakon comes in up to 8-poles, 30A per pole. They are very widely used in the pro audio world to connect audio amplifiers to speakers. The quality is what you would expect with high-end professional equipment. One design goal was to not have any exposed metal conductors on either connector when they are un-mated.
I never thought to use them for a machine tool. But it would work and I *THINK* I'd never make the mistake of plugging my guitar amp into a milling machine axis.
