What is the standard connection of a XLR-5 connector for a stereo microphone?

[RuudNL]

I own a couple of stereo microphones, but it seems they all use a different adapter cable from XLR-5 to 2x XLR-3.
Of course this is no problem as long as you use the correct cable for a certain microphone, but I would prefer them all to follow the same standard.
Most cables use pin 1 of the XLR-5 connector for the screen.
In most cases pin 2 of the XLR-5 goes to pin 2 of the XLR-3 (left)
pin 3 of the XLR-5 goes to pin 3 of the XLR-3 (left)
For the right channel it seems there are different thoughts...
Pin 4 of the XLR-5 goes to pin 2 or 3 of the XLR-3, and the same goes for pin 5, causing out of phase situations when using the 'wrong' cable!
Who knows what the standard connection shoud be? (In that case I can reverse the wires in the microphones that need it.)

EDIT: One microphone manufacturer even thinks that pin 3 of the XLR-5 should be connected to the shield of the cable, and 1-2 is one channel and 4-5 is the other channel...

My hunch / guess would be there IS NO standard, unfortunately. I guess that would explain the wildly varying pinout between manufacturers.

That is indeed what you would think, although I would assume that manufacturers such as Schoeps (MSTC 64 U) would have set a proforma standard. Maybe I should use the Schoeps norm as standard?

Well, you know that old saying - "assumption is the mother of all f**k-ups" ;D But as long as you have the appropriate adapters / splitters, i guess it doesn't really matter which wiring scheme you go with, as long as you keep it consistent among your mics

I don't recall ever seeing any XLR-5 inputs on any gear - but then again, i'll admit i haven't seen all THAT much to begin with

The shoeps pinout is what makes most sense i think. Pin 1-3 does the same thing as in an xlr. 4-5 replicates 2-3. And left channel on first pair, right on second.

When there is no standard, go for the simplest case...

There is AES14-1992 standard saying

Two-channel, balanced
1 - Screen
2 -  Left-channel, positive polarity
3 - Left-channel, return
4 - Right-channel, positive polarity
5 - Right-channel, return

That's old standard for 5-pin DIN connectors.
There is a lot of examples of misuse of XLR connectors (especially in tube mikes). Pin 1 should be always screen-ground, regardless of pin numbers. Pin 1 on all female connectors is intentionally positioned little bit closer to the front of the connector so always pin 1 (screen-ground)  is connected first and disconnected last.
