    Looking to replace gottlieb system 80 IDC connectors with crimped connectors.

    Where can I purchase the connector housing?
    Does someone offer them in a kit.

    Thanks

    You can use a standard molex .156 pin, they actually fit in the IDC housings once you pull out the idc terminals. Does not look as clean as using the correct housing but will save you some money. Just be sure not to get trifurcon, they will not work. I used gold .156 when I did my Black Hole.

    Don't spend the extra money with gold contacts in the future. Gold on tin is not a good idea as the two dissimilar metals will cause a chemical reaction over time and become less reliable than tin on tin.

    But the strange thing about this -- ALL of the IC manufacturers push gold plated IC sockets for use with tin plated IC legs. I was told that due to the air tight connection between the legs and the IC socket, the oxide layer doesn't build up. I guess I can't argue.. but don't really believe them, either.

    I've done this in the past and it works. It's just a PITA pulling the old pin and you're right, the results don't look as nice. In a pinch I'd still do it, otherwise, I just get a new connector.

    Always re-use the original IDC edge connector bodies and install new crimped single side (not trifurcon!) pins. They fit great into the original IDC connector bodies.

    Don't replace the connector bodies please. For one, it's difficult to get all the sizes needed. And two it looks unoriginal and often scary. When ever i see someone has replaced the IDC connector bodies with something else i always go, "wonder if they got this right?" I know that can happen when crimping new pins and using the original IDC connector bodies too, but usually you do that one pin at a time. I see people replace the entire connector and just cut the entire old old (instead of doing pin by pin work). It scares the hell out of me see that...

    Add to that often new replacement edge connectors are gold pins. For the reason Ed states, you don't want gold. And i call BS on the air tight thing. It ain't air tight, there's no way!

    Thanks for the info, placed order with GPE.

    You won't be sorry.
    As noted above...do one pin at a time. It's hard to screw it up. And if you do, it's not going to cause a thermo-nuclear reaction or anything. Your PF switch matrix won't work as expected, but that's about it.

    What about the other connectors in the system 80 backbox, the ones that are not edge connectors, like those to the power supply, do they use the same pins?

    #11 3 years ago

    on the power supply board, which is .156" style, you can use trifurcon pins if you would like. i use them there for example.

    Thanks. One more question, are the IDC edge connector bodies the only ones that can be reused? I mean, I'm guessing that you have to replace the connector body when the .156" style connector is repinned rather than reusing the .156" IDC body?

    #13 3 years ago

    sometimes you can re-use the idc housing / body if you pull the old idc pins out and put normal crimp pins in

    #14 3 years ago

    on the edge idc connectors always re-use the bodies. on the standard .156" molex style connectors on the power supply board, they are usually not IDC. so those you can definitely re-use. if they are IDC i usually replace those as they are easy/cheap to get.

    #15 3 years ago

    With the edge connectors, I'm wondering what size pins to use. There are different size wires, should I use 08-53-0072 (18-20AWG) for the thicker wires and 08-50-0134 (22-26AWG) for the thinner ones? Also, I have the Sargeant 3136-CT crimper, which crimps both the insulation and wire at the same time, should I be putting the 18-20AWG pins in the A hole the 22-26AWG pins in the B hole?

    #16 3 years ago

    For 3136:
    A Cavity = 22-26AWG (will also do 20AWG but not perfect in accordance with ANSI WHMA specifications...as if anybody here cares)

    B Cavity = 24-30AWG

    Not sure why they no longer mark the tool with wire sizes.
