Rectangular Connectors - Headers, Receptacles, Female Sockets

D-subminiature connectors, also known as D-sub connectors or DB connectors, are a family of Polarized electrical connectors often used for computers, servers, and other data communications equipment. They are the most popular type of electrical connector used in data communications and can be found in many industries such as medical manufacturing, automotive, aerospace, and industrial automation. The D-subminiature is available in a variety of sizes, configurations, and contact arrangements, and is typically available in two main shapes: Square and Rectangular. The 643430-1 Application Field and Working Principle are important to understand when selecting the right solution for your specific application.

643430-1 Application Field

The 643430-1 application field includes sensitive electronic devices, communication systems, and computer systems. The D-subminiature connectors are used in these fields due to their high reliability and performance. They are particularly well-suited for use with sensitive electronic signals, as they provide low capacitance, low contact resistance, and a high degree of EMI noise shielding. Additionally, they can be used in harsh environments, as their durable construction can withstand shock and vibration.

643430-1 Working Principle

D-subminiature connectors typically consist of a metal outer shell with an insulating center. A connector pin or socket is inserted into the shell, then a contact is attached to the inside of the shell. The contact then connects to a wire or circuit board. The contact is made using a "pin and socket" method, where the contact pin is inserted into the receptacle. The contact is held in place by a spring action, and creates an electrical connection when the pin and socket are connected. The D-Subminiature also has a "keying" feature, which prevents mismatching by having a keyed ID that matches the shell.

D-sub connectors are highly reliable and highly customizable. They are available in a variety of sizes, configurations, contact arrangements, and even panel-mounted versions. As such, it’s important to select the right connector for your application. The 643430-1 provides a wide variety of features, making it an excellent choice for a variety of applications.
