50-Pin D-Sub Connector, Size 20 Contacts, Insert Arrangements
50 pin Dsub Connector, Contact Arrangements
The 50 pin D connector shown above is a High Density, 3-row D-type connector.
The 50 pin connector may be terminated using any of the following terminal styles; Crimp, Solder, Insulation displacement contact (IDC), or Printed wiring board (PWB).
There are three general types; Standard density (size 20 contacts), High density (size 22D contacts), and Standard density (size 20 IDC contacts)

Designer note; The two other Dsub style connectors that could be used as an up-grade path are only produced in 51-pin versions.
A three row version under MIL-DTL-83513, and a single row version under MIL-DTL-32139. In addition to those two examples, another similar style is the MDR type connector.
MDR stands for Mini Delta Ribbon, a connector style using 0.050 inch spacing. However the MDR type is a ribbon style pin connect, that is, the pins are arranged on a header and not set as individual male/female sockets. In other words the 50-pin MDR connector will not mate with a 50-pin D-sub connector [as defined by MIL-DTL-24308]. For example SCSI I uses a 50 pin MD type connector.
The connector shown to the left is a right angle Printed Wiring Board [PWB] mount 50-pin connector. The connector shown at the top of the page is a straight-thru 50-pin cable connector.
Note the flange for mounting to a panel or case.
