standard ethernet pinout for M12 A coded

Question

I would love to follow the most common pinout (I design connector and receptable, but you never know).

I find conflicting sources:

-RJ45 connector exact same pinout number by number:

-A big cable producing brand Turck seems to have another "standard", I did see this at one of our clients:

Or, is there no (de facto) standard?

UPDATE: we are using the Turck standard on all our cables now. This seems the de facto standard.

Mouser M12 Vs RJ45

On page 2 of this info sheet from Phoenix Contact, it says "There is still no agreed standard on wiring an eight-pin variant for Industrial Ethernet."

Hope that helps

thanks. FYI I got an answer back from Turck. They labeled their own pinout as "CORRECT" and the pin-by-pin with RJ45 connectors as "INCORRECT" (but I guess, that's their view :) ) – lode May 15 '17 at 21:42

Below a table I made of the most widely used standard I have seen. Hope this helps someone out. This does match the "Turck" standard.

This confirms the "Turck" layout from in the question. I have indeed not seen other layouts since. – lode Dec 08 '22 at 22:38

I use M12 A-code. But I decided to use the same standard as X-code. We now always order cables from China.
