Which cables/plugs can be used for steppers?

[jaru-eri]

Where can I find inexpensive cables and plugs for my steppers. Can 6 pins firewire cables be used or will they be to weak for the currents?

Any suggestions?

I believe a firewire cable would probably have too thin conductors for your average stepper motor. The wire gauge determines the current carrying capability, e.g a quick link I Googled:

As for connectors D-sub connectors (such as the one used for the serial or parellel port) can work well, I belive they're usually rated around 5A per pin. Molex mini-fit are another type of low cost connector that should work well.

Try your local electronics store? I see you are in Norway so I'm not sure what's out there. I'm sure there are a few companies who sell out of catalogs (RS electronics?).

There are a lot of options in the US but it probably wouldn't make sense for you...

Several choices for you to choose from.

I used Starquad mic cable. The conductors aren't particularly heavy duty, but the cable is intentionally very flexible therefore well suited to repeated stressing on a CNC machine. Starquad had 4 conductors and a shield (which I didn't use in the end), and is made by Van Damme. As for plugs, I didn't bother since my machine is self contained and it's possible to damage the driver board if wires are accidently disconnected. However, anything which can handle your current levels would be suitable. Again from the audio world, XLR-type connectors could be good since they have locking latches.

something like this? http://www.futurlec.com/XLR-5Pin.shtml

locking latch and that super neutric strain relief

Yup, something just like that! The most common type have 3 pins only, but like the ones you have found, they are available with more.
