D Sub Connectors & Components

D-Sub type connectors are a common type of electrical connector often found used with computers systems such as the connection between a monitor and a PC or used for RS-232 serial communications, although their use in modern computer systems is declining. Other applications for D-Sub connectors include joystick ports, parallel ports, power supply connections and Controller Area Network (CAN) ports. Their continued use is down to their durability and compatibility with existing legacy equipment.

These versatile connectors take their name from their characteristic D-shaped metal shield, which helps provides mechanical support when mated. Usually housing two or more parallel rows of connector contacts and available in a range of sizes such as DE-9, DD-50, DB-25 with the letter determining the shell size and the number denoting the number of contact positions. Other versions such as the DB13W3 contain ten ordinary contacts and 3 coaxial connections, demonstrating the durability and diversity of the D-Sub connector family. Panel mounted versions of this connector generally feature threaded inserts that accept screws from the cable end of a mating connector to assist in locking the connectors together.
