IDC 40-pin connector for 80-conductor cable?
DaveC
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...

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.

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:
http://www.allelectronics.com/make-a-store/item/RAH-40/RIGHT-ANGLE-HEADER-40-PIN-MALE//1.html
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 ...

Either the pins will be what he needs or a male connector won’t do it
wither. It will come out the same unless he twists some strands of the
cable.
Think about it.
I don't know why somebody would want a male end on a cable, anyway. The pins
would not be protected and get bent when in storage.

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

No it doesn't.
There's no way to get 2 female connectors to mate pin 1 to pin 1.

Let us know how it works out.
Michael A. Terrell
It won't work. You can't just solder two connectors together. That
will swap the odd & even pin numbers and short out the entire buss.

You might as well go to a 40 conductor cable if you do that. The 80
conductor cabe is a set of transmission lines and the reflections from a
mix of 40 & 80 pin conductors will screw it up.

There are two types of connctors. One AMP and one other, i think ansley,
but i'm not shure. They use different pins for the stiped wire.
As long as you dont mix brands, you have no problems.
But it can be used to switch pins.

The lunacy never ends.
The pins are NOT defined by a brand name, idiot. They ARE defined by a
standard.
So IF you "found" a connector that was a different pinout (I doubt it),
you were looking at a company that is or would soon be belly up.
Do all gang boy generation retards have zero common sense?

Seems that way.... :)
The Ghost In The Machine
THIS IS HILARIOUS YOU HAVE AN 80 CONDUCTOR RIBBON CABLE?
JUST TEAR IT RIGHT DOWN THE MIDDLE AND USE THE 40 PIN CONNECTOR
AVAILABLE OF YOU EVER FIND ONE....OR DISCARD THAT IDEA AND GET A
PROPER READY MADE CABLE.
WHAT EVER YOU DO, DO NOT LISTEN TO TERROLL HE'S A FRUITCAKE STUCK ON

Actually there are three kinds of connectors for this application and
they are color-coded (black, blue and grey).

Wrong. There are three types of UDMA connector for UDMA applications.
Show me where that is what he asked for.
Note that he made NO request for any such item. He asked about a 40
pin parallel row (IDC) ribbon cable connector.
Since UDMA connectors typically have molded in keyed pins (not
useable), I doubt he wants a 39 pin connector.
IF he does want a UDMA connector, there are plenty to be found.
He wants the male header though, and that will NOT be a ribbon cable
crimp-on item, though they do exist.
