Potential problem with db37...Please help

Pages: (1/3) > >>

dema:

Okay. I just cut a db37 cable in half and I just realized a potential problem. The cable that makes up the 37 pins is very small, and I'm guessing it's smaller than the 22awg limit on the female disconnects. This could be a problem when it comes to crimping, since I doubt they'll work. I suspected this could be the case when I saw that the cord wasn't much thicker than a db25 laying around, but I didn't realize how small they actually were.

Is this really a problem as I'm suspecting or is this something that can be worked with? I'm guessing that if this doesn't work that I can always buy the db37 ends and then solder 22awg wires to the connectors, and then set up the interface I had planned.

Any help would be appreciated.

I used cat5 cable for connecting my controls.  I believe it is also smaller than 22awg.  I stripped 3x the length I needed.  I then folded the wire 1/3 the way down and then folded it again so I had 3 strands side by side.  I was able to crimp the quick disconnects onto this just fine.

I was wondering if that worked but the problem I have is that the wire is too small to strip with the tools I have. It looks like I'm going to have to buy wire and solder it to a db37 connector.

Thanks for the information though.

Just wondering why do people say not to use single strand copper like CAT 5 which is 24 AWG.  

Why is it recomended to use 22 AWG multistrand copper?

CAT5 is acceptable.

My experience is single strand tends to be more brittle (breaks sooner if you bend it back and forth) and also tends to be harder to get a crimp connector to attach to.

But either one can be used.
