I'm doing a bunch of boxes, in this same enclosure,

https://www.dropbox.com/s/43gma000fpuocyf/T130_box.jpg?raw=1

and I'd like to have all the boxes have an auxiliary connector, with a
few analog and digital i/o's and such. I could use an ancient D9
connector, but it would use a lot of panel space.

Is there a more modern, maybe circular, connector that is popular in industrial/embedded applications? Well, there are about a million but
I was wondering is there is anything like a concensus of what's a good connector. Ideally there would be some standard cable assemblies,
breakouts, things like that.

for simple IO is often see things like https://www.digikey.com/en/product-highlight/c/cui/pluggable-terminal-blocks

or maybe mini-fit/nano-fit

We mostly use M8 and M12.

To make a foolproof connection, go connectorless. IRDA is classic.
As for the 'standard cable assemblies', ya can't beat air for supply-chain availability. And, there's not a whole lot of damage your clumsiest
user can inflict.

That, of course, won't work if you need a galvanic connection to a
specific signal...

OTOH, I am seeing variations of this becoming more commonplace,
in designs. The "RdTd" hidden serial port has become a vulnerability
in many designs. When I queried my colleagues for baud rates to
support in a small terminal server I designed, the list was
amusing -- few recognizable hardware protocols or configurations!

Users will tinker -- if they THINK they know what they are
tinkering with (relatively easy to trace foils if you are
using OTS devices). "Wireless" (regardless of technology)
raises the bar. Even if they *think* to look for such a link,
bastardizing protocols (and encrypting traffic) quickly close
off that attack surface!

[And, nowadays, the cost of such a link is often on a par with that
of a physical connector]

some 15 years ago I used this one, still available:

https://www.mouser.bg/ProductDetail/Hirose-Connector/LX60-20S?qs=XQjbzJWzFPUlja7Rly0Ljg%3D%3D

not circular etc. and no idea how popular it is, but well, I have
used it and perhaps I'll use it again.

And they aren't expensive either, the 6pin m12 I'm using is $16
per connector pair.
Kinda short on space in the shell though. Tight fit.

Plus you can get pre made cables.
