Hi there, I would appreciate some assistance trying in figuring out what this logic board connector is, and if the female version of the connector is in stock at Core Electronics, a link to the item page. Note the 3 grooves. ![wtf is this connector](https://canada1.discourse-cdn.com/flex028/uploads/core_electronics/original/2X/b/bf40ae9d5e1e9f26b9e94d26ff0e50bcb85e28c2.jpeg) Cheers. ---

Hi Matthew, I haven’t seen that connection before. What’s the board it on? Bryce Core Electronics | Support ---

Hi Bryce, This socket is on an industrial-grade motherboard that I’m servicing. It provides a debug interface that’s exposed via the 10 pins. ---

Hi Matt, Looks pretty well proprietary. Maybe if we had the make and model of the board you may be able to find a spare part but don’t think we will have it at core electronics. ---

Yeah, that’s what I thought. The instruction manual doesn’t detail anything about this connector, however. It’s more so one of those secret connectors. ---

Hey Matthew, Yes, as Mitchell said this may be proprietary, if there’s anything else that we can do for you please let us know. Bryce Core Electronics | Support ---

I’ve just been through RS Components list, about the closest I could find was a Hirose DF11. Maybe do the same with mouser - just filter to 10 pin, 2 row, SMT, polarized pcb connectors and start scrolling. Also try the Element 14 forums. They’re a fairly switched on bunch. Looking at the guide slots/keyways, it should be pretty visibly unique. ---

Hi all Looking closely it could be a 20 pin connector with only the 2 middle rows (10 pins) fitted. There are literally thousands of connectors out there. If anyone has a copy of the Connector Cyclopedia you would probably find it. 3 volumes each about 50mm thick last time I saw it. Just about every connector known to man complete with tech data is listed. Cheers Bob ---

Still think it is a 20 pin connector. Try AirBorn Inc. verSl. They have connectors with the same polarising slots but seem to start at 40 pin. This may be a starting point. Cheers Bob
