Please recommend me a source of good quality jumper wires with Dupont connectors

(1/4) > >>

Hello, I'm looking for some of these 40 something ribbon cables with Dupont connectors (M/M, F/F, M/F) that can be split as needed, they are allover EBAY and Amazon, not to mention Ali, the problem is that they are crap de crap, excuse my French  :palm:.

Something like this, but less crappy:

Really the contacts seem to be made out the most dead and soft metal possible, with zero elasticity and miserable tolerances, really after 2-3 insertions they're practically falling out the counterpart, not making contact or being oversized and destroying their counterparts. I have some old wires, that slide so nice and fix, in and out, from some logic analyzer probes, something like more than 20yrs. old and they are perfect.

So my question is, where can I find some of the higher quality ones, maybe not Pomona high, but not really crap made out of crap.

If it's available in EU/DE, is even better, but at that point I'm willing to even buy some from US or whatever.


Mr. Wizard:
I don’t have a source for premade wires, but I had the same problem about ten years ago. If you can’t find any good ones, one option is to make your own as needed.

About ten years ago, I bought the Pololu 16-28 AWG crimping tool. It double-crimps and is designed for these types of connectors. I bought crimp pins and housings elsewhere, but I see that Pololu also sells crimp pins, both male and female, along with crimp connector housings in various configurations. I buy my wire from McMaster Carr, and for stripping, I use the Irwin 2078300 self-adjusting wire stripper which instantly strips insulation to any length.

It’s more work than just peeling off some wires with connectors already on, but being able to make the wires exactly the right length keeps things tidier. I particularly like having the connector housings on the end be 4x1 or 8x1 + 2x1 or whatever is appropriate, rather than a bunch of dangling 1x1 connectors.

Thanks Mr. Wizard, I have considered this route, but is fiddly and time consuming  :-\, the only redeeming quality that I can see is indeed to have tailored housings and not individual wires.
I will consider it again if nobody comes with a premade alternative.


Mr. Wizard:
Just wondering—for me, my biggest problem with durability has been with male-to-male jumpers for prototyping use on breadboards. The pins would break off. Similar for you? Female ones seem OK and durable. I’ve ended up switching to 22-gauge solid-core wire for male-to-male connections. I make longer jumper wires myself, but also use these Elenco JW-350 kits consisting of premade wires. I’ve bought at least ad dozen of those kits.

When I need to go male-to-female, these days I’ll typically just plug those wires into the ends of female-to-female jumper wire. However, this is only for temporary, prototyping use. For finished projects, I make my own wires as described in my previous message.

Pololu sells what they call Premium Jumper Wire in various lengths and colors, M-M, F-M & F-F. I have not used them so I can't vouch for their quality:
