I would like to identify this connector in order to buy it This is the same size as DB25 but this is not with pin like on the parallel port enter image description here

    \$\begingroup\$ Looks like a 50-pin connector which was used for SCSI way back in the day ... \$\endgroup\$ – brhans Jun 4 '18 at 19:46

    \$\begingroup\$ Could be something like one of these Hirose DX connectors. \$\endgroup\$ – brhans Jun 4 '18 at 20:21

    \$\begingroup\$ Awful picture - I'm sure you could have done far better. \$\endgroup\$ – Andy aka Jun 4 '18 at 20:23

    \$\begingroup\$ When taking a picture for connector identification, please put a ruler next to the thing so that there's a way for us to determine its physical size as accurately as possible. There's a few 0.100"/2.54mm whiteboards in the background but they're too distorted to work as a size reference. From the photo it's hard to tell whether it's a Centronics (IEEE-488 or Parallel Printer or SCSI-1) or a Hirose DX, both look similar but the Hirose DX is a bit smaller. \$\endgroup\$ – MarkU Jun 4 '18 at 20:40

    \$\begingroup\$ You should measure the dimension over the latches or between the first/last pin centers that corresponds to the data sheet @MarkU posted. \$\endgroup\$ – Chris Stratton Jun 7 '18 at 16:44

Looks like Hirose DX20-50P(55) or DX40-50P-55. Hard to tell from your photo but I think it looks smaller than Centronics. Suggest you check the measurements in the catalog to confirm.

Centronics 50 pin. Popular for SCSI 1

EDIT: Latches don’t match as brhans pointed out. Could be Micro DB50.

    \$\begingroup\$ Looks much smaller & higher-density than SCSI-I, and the latches are different. \$\endgroup\$ – brhans Jun 4 '18 at 20:12

    \$\begingroup\$ This is clearly not the same connector. \$\endgroup\$ – Chris Stratton Jun 4 '18 at 20:20
