Introduction to D-Sub Connectors

A D-sub connector, often referred to as a D-sub or DB connector, is an electrical connector used primarily to join two pieces of printed circuit boards or other electrical equipment. The name D-sub is derived from its shape—two rows of perpendicular pins forming a "D" shape. The number of pins in a D-sub can vary from two pins to over 100 pins. The pins in the connector are soldered to the printed circuit boards, and the shells on the outside of the connector are generally Screw-Lok or Bayonet-Lok types.

The components of a D-sub connector include the hood, terminal contacts, and cable. The hood is the metal covering that encloses the contacts of the D-sub. It also serves to protect the spring-action contacts, which make a connection with the contacts of another D-sub connector.

4-1393479-2 Application Field and Working Principle

The 4-1393479-2 D-sub connector is a type of D-sub developed by the company TE Connectivity. It is used mainly for data transmission applications in industries such as telecommunications, industrial automation, and aerospace. The connector has a robust metal housing that provides reliable electrical contact and protection against external interference. It also has a fast and reliable screw-and-cable connection which allows for easy connections and disconnections. The connector is designed with a standard 50-micron gold plated contacts in order to ensure maximum reliability during transmission.

The 4-1393479-2 D-sub connector is designed to perform both in the office and in harsh industrial environments. It is engineered for quick and easy installation, and its robust design ensures reliable operation over an extended period of time. The connector is also designed to meet the stringent UL environmental standards. It is capable of operating over a wide voltage range from 5 to 20 volts. The connector utilizes a “pipe-and-cable” connection, in which a metal tube is used to protect the cables and contacts from mechanical damages and environmental stresses.

The 4-1393479-2 D-sub connector uses differential signal transmission for reliable data transmission. This type of transmission utilizes two complementary signals which are sent simultaneously over two different channels, as opposed to the single-ended transmission which only uses one signal. By using two signals, any signal noise that is picked up during transmission is canceled out, thus ensuring a reliable and interference-free signal transmission.

The 4-1393479-2 D-sub connector is a robust and reliable data transmission solution for a wide range of industrial applications. It is designed to guarantee a high performance data connection and ensure long life operation in harsh environments. With its corrosion resistant contacts and a robust metal casing, the 4-1393479-2 connector stands out as a reliable and durable data connector.
