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.

The problem with those connectorfs, and the Weidmuller equivalents, is
that humans aren't strong enough to un-mate them. And the spring-push
wire clamps are flakey. And that they have no no opinions about pin
numbering.

We've used a lot of those plugable connectors, never seemed like a
problem to unmate them

 We used a similar part, and it was very hard to un-mate. We use the
version with the cam now, but only a few of their connectors have the
un-mate cam.

if there no number you decide what to call the pins

 And since the connectors are unmarked, we have to explain the pin
numbering to our customers, with pictures in manuals.
 

if it had numbers you'd still need to explain what goes to what number, or just have the names/numbers on the box next to each pin
