1731120142 D-Sub, D-Shaped Connectors - Contacts

D-Sub, D-shaped connectors (contacts) are electrical connectors designed with a D-shaped metal housing designed to house multiple, parallel pins or sockets. These types of connectors are most often used for carrying digital signals, serial data, and low voltage DC power. They are manufactured in male or female genders and have typical applications that include computer networking, industrial automation, audio/video, and automotive electronics.

D-shaped contacts are most commonly designed with a single "pin" or "socket" on each side, however multiple pin/socket configurations are also available. The D-shaped body of the contact is typically made of welded steel or copper material, and is then plated with nickel, tin, or gold for better corrosion and electrical contact resistance. The pins or sockets typically have insulation material protecting the electrical contacts from one another, while their entire length is typically insulated against the D-shaped metal housing itself. The contacts themselves are pressed into the D-shaped metal housing so they become tightly secured.

The primary application for D-shaped connectors (contacts) is to provide secure connections for digital signals, serial data, and low voltage DC power. This is due to their ability to mate easily with their similarly D-shaped counterparts but also provide a secure connection that will not be easily disconnected. With their multiple pin and socket configurations, these types of connectors also provide a mechanism for connection that is space efficient, allowing multiple circuits to be connected in a relatively small space.

When D-shaped contacts are used as electrical connectors, the operating principle is quite simple. As the contact is inserted, its male pins press against the female sockets in the connector, making a secure connection. This connection will remain in place and have a low electrical contact resistance unless it is purposely disengaged. This makes them ideal for applications that require a secure connection but also flexibility. When used in low voltage DC power applications, the contact resistance is typically less than 0.5 milli-Ohms.

D-shaped contacts are a great choice for a variety of applications, as a secure method of connection is critical for any circuit, as well as space efficiency and a reliable electrical contact. With the various pin and socket configurations available, D-shaped contacts provide the versatility and reliability that most engineers are looking for in an industrial applications. The contacts are designed to be reusable, due to their robust construction, providing the reliability that engineers need.
