[I realize there is another thread about connectors going right now, but that is mostly about power connectors.. ]
For the last two years our team has been doing a modular electronics box that is easily removable, which has been extremely useful for us. We've been using 2 or 3 AMP connectors (similar to the ones shown here:
http://www.newark.com/catalog_129/index.html?page=931) with a dozen or so sets of wires each.
These have worked out really great when they work, and makes it really easy to remove the electronics and insert new things when necessary. However, they have a number of drawbacks:
a) Requires a special tool to insert/remove/crimp them
b) If not done correctly, they can be unreliable
c) Running a ton of wires to a single connector, makes it really annoying to add new wires to it as it fills up
What kinds of solutions have your teams used in the past (or currently) for this sort of thing. We anticipate lots of sensors and motors, so something that is easily scalable would be ideal.
