Does anyone know any brands / part numbers for stiff stranded ribbon cable? I can find lots of floppy stuff but I want to use some for panel / inter-board wiring in the transceiver I am building. Tektronix used the stuff in their kit from the 1970s / 1980s but I can't seem to find it or anything equivalent anywhere. It had the interesting property of staying exactly where you put it. |

Are you looking for standard 50mil pitch stuff? We have some 3M 3801 and 3365 (If there's a difference between the two I can't tell what it is) that's fairly stiff, and can be lightly creased to get reasonable bends. If you were in the US I'd offer to send you some since we don't really use it anymore, but shipping it to the UK is probably prohibitive. |

How come you want the stiff one? I thought it was a complete pain in the ass and I see them fail (for instance APC power supply). But theirs is almost springy. I am curious why you would prefer to use it, unless its teflon or some kind of really tough insulation with special properties. I always thought it might be bad for vibration and I would recommend securing it anyway. Maybe I am not thinking of the same thing as you. Do you mean the rainbow cables? They seem to hold to folds and stuff ( I have seen it in high end IFR equipment). I don't think its stiff but it is malleable. Is your definition of floppy a computer IDE cable, a SATA cable or even worse one of those really floppy connectors you might find in modern appliances (i.e. induction stove). |

Thanks for the replies both - appreciated. This is all internal cabling. It has to be relatively rugged and not flop around inside the device as it’s portable. Solid cables tend to stay put and you can tie them down easier in bundles. Floppy is same as IDE cables. If you have three to four strands of the stuff stuff it stays in straight lines as an example. I tried normal 3M stuff as specified and it is too flexible. IFR kit stuff is about right. I’ve been using some old tek cable but I’m running out of that now. |
