D-SUB Connectors & Hoods

A D-SUB contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support and some screening against electromagnetic interference. The D shape guarantees correct orientation. The part containing pin contacts is called the male connector or plug, while that containing socket contacts is called the female connector or socket. The contacts in these connectors are spaced approximately 0.108 inches (2.74 mm) apart with the rows spaced 0.112 inches (2.84 mm) apart.
