I would use (say) pin 1 as common (earth, 0V) then pin 2 is 5V , pin 3 is 12 V, pin 4 is 15V DC, pin 5 is 12V AC, pin 6 is for future use).
That way it will not matter which plug/socket is used as only the right power reaches the other connector (which is always 2 way, round or USB).
Make sense?

Yes I understand now.
That works as long as no two equipment connectors share the same type of plug/socket. If there is any chance you could plug the 12 volt connector into the 5 volt equipment, for instance, then no.

The 12 volt AC output may cause some tears as half a bridge rectifier will end up across the supply.

One of my recorders uses a small locking Hirose connector for power, have not come across these anywhere else though.

Litepanels use 3-pin XLR for power connection to LED panels but I think the other end is either hard wired or a different connector.

Another suggestion is to use coloured sleeving on the cables perhaps using a coloured marker on each piece of kit to help identification.

Another connector option that is relativly small but can hande decent currents is the speakON connector, designed for connecting speakers to amps but I know Blue microphones has used it for low voltage power before. 2, and 4 way connectors that fit in to D type mounts and 8 way connector that fit into G type mounts available , with an 8 way connector you could even wire it so all sockets have all voltages so long as no more than 1 AC and 5 DC or 2 AC and 3 DC Etc. voltages are required.

There are also 7 pin XLR's, these 8 pin locking DIN's https://www.thomann.de/gb/ultralite_din8rst.htm, or I suppose ypu could use Phoenix strip connectors (i.e. https://www.thomann.de/gb/phoenix_co..._3_stz_508.htm )
