I am going to be standardizing on a 12 pin plug, used with six
pairs of individually shielded and drained 20 AWG wire (good for
7 amps/wire continuous).

There are lots of reasons for my using the 12 pins, but it boils
down to that will handle all my different combinations, including:

differential encoders - GND,+5,A&A',B&B',I&I' and four wires for
bipolar steppers (or two paired wires for
DC servo).

single ended encoders - GND,+5,A,B,I, limit+,limit-, home and
4 wires for steppers or DC servo


The connectors and wires are not cheap, but it is the 'right thing'
to do to minimize the wiring mess.
