D-sub connector.

Also written D-subminiature, DB connector, DE-9.

What is a D-sub connector?

A D-sub is the connector with a D shaped metal shell around two or more rows of pins or sockets. The shell only mates one way, and sizes run from the 9 pin DE-9 up to 50 contacts in a DD-50 shell. The pattern dates from the MIL-DTL-24308 military specification. Choose by contact count, gender and mounting, and add a hood where the cable leaves the connector.
