I'm here after spending a several hours at https://connectorbook.com/ and while I learned some terms that describe my mystery connector, I haven't been able to determine a make and model. I hoping y'all can directly identify this connector or add more details that I might use in my search.

From The Electronic Connector Book, I learned that this connector would probably be categorized as board-to-board or single-wall one-row, but I haven't found any images that match yet.

Perhaps the most unique trait is how the connectors make contact -- it's like an edge cross lap joint in woodworking. Anyway, here are measurements and photos. Please let me know whether you want more information.

Measurements

  • application: English industrial motor controller from the late 80s
  • 32 contacts
  • one row
  • 2.54 mm pitch
  • one wall
  • no bumps or latches
  • 101.6 mm long
  • 17 mm wide
  • 7.4 mm tall
  • 88.5 mm spacing for top-facing mounting holes
  • 95.2 mm spacing for front-facing mounting holes

Photos

  • Detail on pins detail on pins

  • Complementary connector complementary connector

The pins are spade-shaped with a slot down the center. The two connectors press together with the spades rotated 90 degrees from each other.

  • \$\begingroup\$ It looks like the connector would plug into a rotated version of itself, and you have a horizontal and a vertical example. Is this right? \$\endgroup\$

  • \$\begingroup\$ Yes, that's correct. All the photos are from the same connector except that last one, which is a vertically oriented one on the "main board". I took the most photos of the "plug in" board, which is a horizontally oriented connector. Both connectors have the "one wall" feature and only connect in one position. \$\endgroup\$

  • \$\begingroup\$ If it's 2,54mm pitch then there are countless replacements. Unless you are pedantically concerned about authenticity (because you work at a museum or something), just rip the damn ting off and replace it with a header strip or box header. \$\endgroup\$

I remember those hermaphroditic contacts, but from well before the 1980s. ca. 1970, maybe. They are associated with EDAC now.

No idea if they still make the ones you show there.

    \$\begingroup\$ Thank you! They still use that contact design, but whether I can find a seller for these is a task for tomorrow-me 😄 My estimate of the vintage is from the manufacturing codes on the ICs, but the connectors have no (uncovered) markings or identifiers that I can see. \$\endgroup\$

    \$\begingroup\$ @user1635886 This is the closest one to yours that EDAC still lists. It's not yours, though. Yours must be obsolete. \$\endgroup\$
