HD-26 Connector

gnuarm.deletethisbit 8 years ago

I found out the HD-26 connector specified in EIA-530 was only ever used ext ensively by Cisco. They stopped using it some years ago and so suppliers s topped making the panel side dual height stacked connector. My customer st ill uses it on their equipment and found that a local cable house had a con tact who is now making it as a custom for my customer.

It is a D shell shape with a much smaller pin spacing than a DB-xx connecto r, that's the appeal. It uses the same jack screws and seems pretty solid.

Anyone use this HD-26 connector? Where are you getting them? I can find l ots of cables, but not the panel/PCB mount connector.

I use a VERY small number of these on some motherboards that hold a bunch of boards we make. So, in the last 10 years I've used a couple dozen of them. I generally get them from Mouser or Digi-Key. I have right-angle PCB-mount male ones on the board, and a female cable-end to mate with it. But, I haven't bought any in a while. The jack screws, hoods, etc. are identical to the 15-pin standard connector. These are from the same series as the 15-pin HD connector familiar on computer monitor cables "VGA".

(I sure hope they don't stop making these!)

No, wrong connector. Those are D-subminiature connectors, known as a DSUB HD 26. That family of connectors has round pins and sockets. This connect or has a center paddle that supports blade pins not unlike a USB connector or the old Centronics connector but smaller, much smaller.

Here is the cable with a D-sub on the other end.

This shows why they are used. I guess Cisco found something even better.

I guess no one ever reads past the first post in a thread before posting a reply... still not the right connector, but thanks anyway.

I heard back from the folks who make these for my customer, or rather the U S company who contracts with the Chinese company to make them. I don't hav e a price as yet, but the two gang version has a minimum purchase qty of 1,

000 and a lead time of 6 weeks. So not much different from the major manuf acturers except faster. It would be nice to find a source that uses stocki ng distributors though.
