What is the smallest plug and receptacle you can buy with 4 or more conductors?

parts

Here is what I've been able to find: Receptacle: http://www.te.com/catalog/pn/en/1589691-5?RQPN=1589691-5

and

Plug: http://www.te.com/catalog/pn/en/1589056-8?RQPN=1589056-8

Bonus points for: mil spec, able to fit into an inside diameter of Ø .14" :)

Edit: Thank you for all your help guys, you've shown me two more companies I wasn't aware of. I'm still shopping around for one that fits in such a tiny place.

I assume you've looked through Glenair and Amphenol Aerospace's catalogs? They're the people for milspec connectors.

It sounds like size is the defining factor, so D38999 connectors are probably out.

I'd take a look at Glenair's Mighty Mouse and Mighty Mouse High Density connectors. LINK. They've got a wide range of mil-spec stuff, from naval to aerospace to ground. Some of the denser connectors are the Series 811.

Feel free to ask more questions, I've spent a lot of time with mil-spec connectors. It'd be helpful if you'd share more about the application. High speed, high bandwidth? Power? Ethernet?

I'm going to take a look at Glenair, thanks a bunch for that recommendation. I'm looking to put together a stem 2" long of Ø .0157", that which I want female recepticles on either end. Hope to find something I can cram into an I.D. of .014" The ones I found are just a cunt hair too large..

Edit: typo one more order of magnitude larger on that OD .157" and ID .14"

I mentioned this to a guy at work who is very familiar with Glenair's connectors. I overheard him on the phone with a Glenair salesman; the smallest connectors Glenair makes, price not a factor, is the Series 88 SuperFly. Their smallest shell size has an outer diameter of 0.317 in.

Can you share more about your application? What kind of "mil spec" do you need? Typically if you need mil-spec, it's not something that optional.

LEMO have some really small connectors.

I use 3.5mm TRRS all the time for consumer stuff, but I wouldn't know about mil-spec. Are you looking for smaller that that?

If I could find a 2.5mm female barrel sub-assembly that I could cram into an inside diameter of Ø .14" that would be great! I've looked into this option.. just can't find any sub-assemblies that don't include the outer barrel jacket.

micro USB?

There are connectors around half the footprint in just LxW

Do you know of any that would squeeze into an inside diameter of Ø .14"? USB would be awesome, the more standard it is the better :)

So you probably need a high cycle count as well? That's a deal breaker, I think, unless you can tolerate something like mini-TRRS, which is trading cross-sectional diameter for length.

Cycle count shouldn't be too much of an issue, I would estimate each plug being cycled <15 times a year.. and length isnt much of an issue as compared to diameter which is the main factor. It's looking more and more like Ill need to get my CAD skills in order and make it myself! Im much more experienced drawing PCBs than I am drawing hardware
