Help to Identify a wire to board(?) connector from an old arcade/pinball machine

stanto over 2 years ago

pcb

A fellow member of Leeds Hackspace works on arcade and pinball machines and has asked for help in identifying these white connectors. Pin on header is 0.9mm wide by 0.66mm high, 5.5mm deep, with 2.54mm spacing. I was thinking something molex or jst, but I cannot find anything online with my limited skills.

Thanks!

I don't know the answer to that, but presumably then a special crimp tool would also be needed, for the mating connector. Maybe it's worth just soldering on a normal pin header to that, since it's 2.54 mm spaced. (if it doesn't matter that the header would extend out from the board a bit). It would be easy to strengthen with (say) Polydoh.

This may be the housing for the mating 25 pin connector: pinparts.co.uk/.../crimp-housing-0-dot-156-pitch-choose-size https://www.marcospecialties.com/pinball-parts/CF10025

and for the 4 pin one: www.moneymachines.com/.../

It could be an obsolete Molex connector series....maybe these guys make a replacement...

We're starting to think it's something like this:

The board's from a Taito Continental Circus, the guy's wanting to maintain a bunch of them, "That connector with same pinout is used on a few Taito boards so I want a bench harness to test them rather than to mod a single board" (to address shabaz 's suggestion)

Looks like that's it... I ran the CAD model on the JST website to see the measurements, if your friend wishes to compare with calipers:

I don't believe they have access to tools to do so at the moment, but that's a good idea.
