content: Hi all, I am looking for small quantities (~3 pairs) of small wire to wire connectors for 4-6 wires. This is for a one of application with tight space. I plan on using 30AWG teflon wires. Ideally the connectors will have small pitch but not too small so I can assemble it by hand, may consider 0.1" pitch but would prefer denser.I looked around and could find many wire to board connectors but not wire to wire. I am located in the US so prefers products I can purchase locally (e.g. digikey, mouse, etc). Price is not a big issue but need to be reasonable (let's say 5-10$ per pair).Thanks,Z.

content: Would micro-USB be small enough? You can buy extension cables and cut them in half.

content: Sorry, I misunderstood. Your best bet would probably be a circular connector, something likethis.

I need some time to process it.Edit: I looked at the Molex site and it seems that this one:http://www.molex.com/molex/products/datasheet.jsp?part=active/0701070004_CRIMP_HOUSINGS.xmlAnd one of these:http://www.molex.com/molex/products/datasheet.jsp?part=active/0050579305_CRIMP_HOUSINGS.xml// polarizedhttp://www.molex.com/molex/products/datasheet.jsp?part=active/0050579405_CRIMP_HOUSINGS.xml// polarized and lockingWill do the job. I will give it a try. Thanks everybody for your help.

content: A quick followup, Per one of the suggestions I used digikey WM2536-ND + WM9137CT-ND and WM2903-ND + WM9139CT-ND and was happy with the results. I did not have a compatible crimp tool so used short nose pliers and a soldering iron.
