[Member-Forum] Motor Controller Ribbon Cable

Wed Feb 5 03:47:31 EST 2014

Hi James & all,
With standard 0.05in pitch ribbon cable, aka "IDC", you can get crimp
connectors to go on the ends that terminate into standard 0.1in pins.  They
are cheap and beat the hell out of soldering, especially if you've got a
lot of wires - it also does a good job of strain relief (I have found after
stripping the insulation off, there's not much wire left and it tends to
break under not much strain).

Only trouble is they don't seem to come in "joiner" versions and a quick
google didn't show up too much.  They usually terminate in a female end,
but you could just get some long rows of pins and join 2 females together.

Check out this for the concept:

The crimp ends don't need any preparation which is awesome, although I
usually use a pair of pliers to get them closed.

Actually, here's a pair of male/female (10-way) similar to what you'd need

And if you need male, it would be something like this:

Retail places that sell electronics components on the level resistors and
the like will probably have them, and maybe cheaper.

Hope that helps (good thing RS-Online is in the UK as well as Australia!).

Cheers,
Steve
