Introduction

A D-Sub connector is an electrical connector that consists of two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support. The metallic shield also acts as a ground connection in shielded cables. D-Sub connectors have a Quick Disconnect (QD) version that functions in the same way but without the need to remove the shield when connecting or disconnecting cables. The TMDMC421SH003M7A174 is a type of D-Sub connector.
