Looking for a mini connector...

[fjf]

I need a mini (small!) connector (male and female), gold-plated and shielded. Something like a BNC, but MUCH smaller. Nothing to do with audio, it is to connect microelectrodes to a potentiostat. Anyone knows a source for something like that?. I've been using single pins, but I'm trying to reduce noise and I want to use thin coaxial cable and shielded connectors.

Thanks!

I THINK i know what you are talking about. Can you provide a picture. I may have one if I am thinking about the right connector, if not, I am sure I can get one from my school.

Male:

Female:

The problem with those is that they are too big for this purpose.

RP SMA??

Those look very similar in size to a BNC:

I need smaller.

UFL Coaxial?
Its the tiny little plug. I think they're made for wireless cards...

Hey, we are getting somewhere!:

Now the problem is: a)the male seems to be only soldered to a board, and not to a cable, and b)who sells those?.

a) oddly, you seem to be right, at least from a datasheet found on www.i-pexconnectors.com
b) RS-components. look for ipex. still not much..

Lots of the UFL on ebay (supposed to be used as antenna connections but they're cheap enough to hack up). As for the male, I've never seen one that isn't board-mounted, but you could still use it on the end of a cable with a little heatshrink.

Thanks for the help. I'll look into it. If anyone remembers other type of shielded microconnector, please let me know.

Lemo and Fischer make shielded microconnectors in different styles aswell.
They have coaxial connectors , pin connectors in multi and single contact form, i think the smallest plug is ~6,5mm in diameter, but i might have overlooked something

MMCX is another like UFL.

I was about to mention the LEMO -00 connectors but I suspect even they might be too large for what you're after. They'll probably have smaller ones in their catalogue though.
