If you guys really want reliability, low contact resistance, many cycles (big MTBF), etc
Then why not look at military stuff.
I've used or spec'd to use on my military designs. This one has a
screw on barrel, but they also come in quarter turn and even safety wire
They do NOT have any vibration on the contacts, so they will last forever (almost)
hermetically sealed and extremely low insertion and break-apart forces
Contacts look like this (female half shown and the male half just a
round nosed pin)
Signal level up to hundreds of amperes. More contact surface than the regular
blade or round types
Wiping action the whole length of those spiral female side wires and
can get 'make before break' or 'break before make' or signal or power
in any combo in the same connector...though $$$$
Can even find them in surplus stores and on line too
