That litle green Phoenix connector is cool. Wires screw into it
without tooling, and it's easy to mate and unmate. But it's only 5
pins.

Phoenix  do make 20 pin version (as two rows of ten) with 10 amp per pin on
200 mil pitch.

Do they actually make them m, as in somebody has them for sale, or are they
just listed in a catalogue?
 
Connector catalogs are full of things that they would love to make for you
if you want to order 100,000 pieces and can wait six months.

The nice thing about the Phoenix connectors is that you don't need a
soldring iron or pins and crimp tools to terminate wires, just a small
screwdriver.

My customers like the Phoenix's. We sell ground test gear, not stuff
that flies, so we don't have to use those crazy MIL type circular
connectors.

Somebody does want to fly some P940s, but only in a flying test bed,
so commercial parts are still OK. Some of the boards are heavy and
flexy, so we are adding some vibration damping in the chassis.

(A flying test bed is an old 747 that they swap one engine out, or
strap one more on the side, to test a new engine at altitude. They
fill it with test gear and engineers and witnesses.)
