Does anyone have a suggestion for connectors for the DO board? The connections on my card are the same size and distance apart as the headers for jumpers (64mm -.025"). I basically need jumpers that have wires coming out instead of shorting the contats.Any guidance is appreciater. Could not find anything on Digikey or Mouser.

The headers for jumpers are generally 0.1" / 2.5mm apart, the same distance as things like the pins on IC's.0.025" apart is 25 thou.... a REALLY tiny distance, which is about 0.64mm, not 64mm.As an example for the right type of plug, look at part # 455-1044-ND in the digikey book - thats a two circuit 2.5mm header for crimp-on connection to wire.

Yeah, there are connectors - basically what Richard said - small metal crimp-on pieces that "slot into" plastic "headers" that align those in the 2.54mm grid - those plastic parts are available in different sizes, 1, 2x1, 3x1, 4x1, 2x4 etc..It's the same kind of connectors your PC has for the motherboard "HDD Led", "reset button" etc wires - the CD-Rom audio wire has a 1x4 one.//Tuomas

Great - thanks guys.... they are indeed 64mm (.25)" Much appreicated. I know the things were out there, but sometimes searching the catalogs can be daunting.

Ah, 0.25"..... that's a bit different from 0.025" :-).25" center ones are usually only used for power supply though - they're the big heavy ones. Molex is probably your best source for those.Richard

Richard/Tomas,I ordered and received these connectors and they are indeed the correct size. Now my question become - how do you attach wires to these dodads? I looked in the digikey catalog and the crimpers for these connectors are $200? Yikes. Am I missing something (hopefully... probably?).Thanks.

Hi!I bought a tool for the crimps from rs components and it cost me approx. USD300 and it was even marked "not for industrial use". Isn't this a great hobby! :)You might be able to fix them to the cable by using a standard set of (small) pliers, but I think it will be difficult (and tedious!).Regards,Ole J.

Olly,You got a part number for those crimpers?

>Olly,>>You got a part number for those crimpers?I just used my Leatherman pliers, it's probably easiest to do with real crimping tool (there are cheaper ones around too than $300!!) - what I do, is this:The metal part has two "claw pairs" - one bigger in the end and another pair closer to the "socket" part. The end (sort of triangle shaped) claws fit over the insulated part of the wire, while the "inner" ones fit over the bare wire.What I do, is using the pliers I first fix the ones over the insulation one by one, and then I do it for the bare metal contact. I use the plier tip (the leatherman one is pretty good size, but any pliers with sort of fine tip will do) and I first "fold" one of the "flaps" over the wire, then do the other one.I know a crimping tool will "curl" them against the wire better, so it will probably hold more firmly on the wire, but what I have then done is to heat it with a soldering iron a bit and dab a very small piece of soldering lead (whatever the metal is called in english) on the metal-metal crimp part. I use the very very thin solder lead so it doesnt "flood" the whole thing, just a tiny small bit that sucks into the crimp joint. Has worked for me, but yeah, a real tool is probably easiest.I have seen those for like $50 - but it works pretty OK with pliers too.//Tuomas

Hi!Not at home. Will post the order numbers later tonight.Regards,Ole J. Almenningenhttp://www.737cockpit.nohttp://www.simbuild.com

Sorry for the delay!Anyway as promised here goes: The order number for the Crimp Tool is: 360-6904A pic of it :http://www.almenningen.no/fs/050120_1.jpgRegards,Ole J. Almenningenhttp://www.737cockpit.nohttp://www.simbuild.com
