Connector Experts - Please Identify this connector
« on: August 27, 2026, 03:15:50 pm »
Hi All.
I have a connector on a old BYK-Gardner Gloss Meter.
It's a super mini d-sub-ish connector, black Plastic, super small pins.
Hard to measure, tried calipers, tried a loupe, I get somewhere around 1.00-1.15mm pin spacing, and the same for the row spacing.
It's not the ITT Cannon mini d-sub, as that one has wider spaced rows than pins.
It's not the JST's SR/SZ, as mine has 2 rows, not one.
It could be the Hirose DF9/DF17, or the JAE WP/FI series, or Omron XG4

If anyone can identify this or has any info that you be appreciated.

Tip to measure pitch more accurately - measure multiple pins and divide
Youtube channel:Taking wierd stuff apart. Very apart.

Could it be a Micro-D connector? Looking at the PCB footprints from NorComp (e.g. https://content.norcomp.net/rohspdfs/Micro-D/380-YYY-113L001.pdf), the pin pitch is 1.27mm and the row pitch is 1.10mm.

Also, just to be unambiguous about connector dimensioning: the normal way is the "pitch", which is the distance from the center of one pin to the center of the next, i.e. ignoring the width of the pin itself.

When you say "spacing", you could mean the pitch, or you could mean the space between pins, which is a nonstandard way of specifying it.


It's not the JST's SR/SZ, as mine has 2 rows, not one.
It could be the Hirose DF9/DF17, or the JAE WP/FI series, or Omron XG4
Why waste our time listing connectors that are blatantly obviously not the one you're looking for? None of those connectors is even remotely D-shaped with staggered rows, so there is zero chance it's any of them. You'd know this if you'd looked at them. Just because they have a 1.0ish pitch doesn't mean it's a candidate.

Looks like the body of this connector (black), is made of plastic, which is of similar composition as the blue plastic. It could be a custom molded connector which looks like a mini D.

Any way to open up that blue box and see markings on the rest of the connector?

I don't know what it is, but it really looks like it will mate with the thingo pictured here.
This is one end of a short serial port adapter for an old laptop computer... old enough to have a serial port, and that makes it long enough ago that I can't say who made that computer. Likely IBM/Lenovo.

This cable is useless to me, so I'd be happy to cut it apart to see if there are markings on the connector but I really doubt there will be.

most likely a itt-cannon brand connector. there are other manufacturers. Amphenol aerospace has those too.(but with metal shell)

https://www.ittcannon.com/micro-mdm-with-integrated-backshells

here are the plastic versions :

also known as micro d-sub. digikey / mouser have plenty
