Backplane Connectors

Is it possible for someone to identify these backplane (motherboard) connectors, the ones in brown color? The daughter cards which plug-into these connectors are 3U size cards. This is an outdated chassis. Maybe someone know about these by his old experience.

The connectors have 11+45 = 56 points in a row.

    \$\begingroup\$ It would be useful to know why you are searching for the connector information. \$\endgroup\$ – Michael Karas Aug 22 at 9:47

    \$\begingroup\$ It would be useful if you could add the purpose and rough manufacture date of the board, as that might give some clues. More precise length and width measurements would also be useful. \$\endgroup\$ – Jack B Aug 22 at 9:52

    \$\begingroup\$ It's basically a card-edge connector of some sort, kind of like this one: toby.co.uk/board-to-board-pcb-connectors/card-edge-connectors/… \$\endgroup\$ – John Go-Soco Aug 22 at 10:09

    \$\begingroup\$ Looks a lot like PCI, but unless OP miscounted it is a few pins shorter. The connectors are most likely vendor specific. \$\endgroup\$ – Turbo J Aug 22 at 10:16

It looks like a VESA Local bus, aka VL-bus.

TE makes a couple versions of the 11+45. This one looks closest to the 5650181-1 that links to Digi-Key but they don't stock it. A similarpart 5650090-1 they have but it uses a staggered pinout so you would need to check the board.
