IDC 40-pin connector for 80-conductor cable?

Looking for IDC male connector, 40-pin for 80-conductor ribbon cable.

This is used on IDE hard drives.

Or an 80-conductor cable with 1 each 40-pin male & female connectors.

Can't seem to find a source, but that is probably because I'm not using good search terms...

Anyone know where to find these?

Thanks.

Unless I missed what you're saying, such a cable should be available at any good computer hardware store. E.g., Newegg has them under Computer Hardware -> Cables -> IDE. Some are specifically said to have 80 conductors, but all models specced for ATA133 should be 80-conductor types.

Those are cables with typically 1 female connector at one end and 2 female connectors at the other end.

I need 1 female and 1 male connector.

IDC male 40-pin for 80-conductor flat cable are apparently made from unobtainium...

Oops. Sorry, I didn't read your post carefully enough. The time I needed *that* type of connector which was about 15 years ago for my Amiga, I made my own. I made a small pcb with two double rows of pads for header pins, spaced 0.1". The pins came from jumper headers salvaged from a dead PC card (everything had lots of jumpers those days). Rather tedious but I didn't have any alternative. One end of the female IDE cable plugged into one double row of pins and the other double row was free. If I had to make one again, I'd use a 40-pin IDC header block or the set of pins from an old IDE hard disk.

No male connectors.

This results in reversing the pin assignments, ie, pin 1 connects to pin 2. Not good.

put the female connector on the reverse side in one end?

might even add (or remove) the strain relief that go on top of some idc connector so the connectors will still look to be on the same side

The configuration of IDC connectors is such that you can put the connector on either side of the cable (with the #1 pin indicator at the same end) and you maintain the same pin connections. In other words, you can't reverse pins by flipping the connector.

I don't think you'll find them. The female connectors have shorting links inside and I don't think I've ever seen a male one. Maybe you'll have to lay out a PCB.

UDMA cables have specific "keying" where specific pins are not used.

They are differential pairs where every other conductor is ground.

Try hunting for UDMA male if you can handle the missing key.

Not sure if clamping a standard 40 pin IDC onto an 80 pin flat cable yields the same thing. Probably does as I can't think of anything about a UDMA cable connector that is different other than the blocked pin.

goddamned cross-posting idiot.

Desolder this:

Or buy this:

or buy the pins and make the header yourself without the shroud:

This is also untrue and incorrect. It does not change the fact that it was a stupid suggestion though.

Can you come up with a way to connect pin 1 to pin 1 of two connectors, placed face to face, connected by a 40-pin header?

I don't think they make what you are looking for.

You might be able to fake it with a make-male gizmo. That is plug a bunch of pins into a female connectot to turn it into a make connector.

If you can't find something targeted at that use, a normal through-hole header might work. The board end will probably be too short. Mumble. Solder two together, or push the pins off a bit, or ...

Now comes the big question: why? Do you want one or more of the control/master/slave connectors (control = blue, master = black, slave = blue) on an ultraATA cable to have pins instead of sockets? Then just put a male-male header into a prebuilt cable. You lose the polarizing notch feature this way, of course.

Or, do you just want the 40-pin circuit board connector for a mating connector? Those are available, in straight, right-angle, and various other configurations, and they're just 40-pin connectors, not special because the cable has extra wires.

The three colors of (female) connectors on those 80-wire cables make three entirely different connections. If you don't have the right tooling, it's difficult-or-impossible to crimp them accurately anyhow, so generally no one tries (the mass-produced cables are cheap).

I think you need to get two F connectors and try it yourself. Put them face to face. Pin 1 aligns with pin 2.

The M connector is *designed* to mate with the proper pins. F connectors were not designed for that.

---------------- What you implied was to turn the male header/connector around and face it the other way (face to face means one is reversed). Of course it will be pin

1 to 2. The other side of the cable usually fixes that anyway, like the old days when the IDE cables had no orientation (not racism) gadgets on them.

Not a big deal for somebody without 3D dyslexia. I can prove that by attempting to do crown molding on the ceiling....LOL
