connectors for instrumentation

[Bob Morein]

I have an experimental rig I need to instrument with delicate strain gauge
wires and other sensors, attached to plastic pipes.
I'm looking for connectors that will allow segmenting the wiring.
They need to be balanced, ie., 2 conductor + braid, should be smaller than
XLR, and it would be nice if they were easy to wire up.

I don't think that minature 3 conductor mic plugs are robust enough for
this.

Any suggestions?

I'd be concerned about thermal emf every time you change metals.
