A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield, or shell, that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference.

Sep 27, 2017 · Many people call all D-Sub connectors by a DB name for example they will say “DB-15” which is actually a DA-15 or they will say “DB-15HD” or HD-15 “High Density” which is actually a DE-15. We have assembled the below table to help with shell identification questions. Naming DX-ZZZ. Common D-Sub Connectors. See Also.

May 12, 2024 · It features a D-shaped metal shell housing different numbers of pins or sockets. The pins or sockets are arranged in two rows, with different sizes and layouts depending on the connector’s type. This subheading aims to introduce readers to the basic features, structure, and components of D-Sub connections.

Oct 8, 2023 · Many data communication standards specify D-sub connectors, e.g V.24/RS-232 (DB-25 connector), X.21 (DA-15 connector), etc. The D-sub series of connectors was introduced by Cannon in 1952. There are five basic shell sizes, DA through DE (see illustration).

Products in this family are used for the construction or repair of D-subminiature (D-Sub) cables, so named because of the D-shaped shroud surrounding their mating region and the relatively high interconnect density they offered at the time of their introduction.

Oct 28, 2023 · A D-sub connector is meticulously designed, featuring a series of pins or sockets enclosed in a robust D-shaped metal shell. This design not only provides mechanical support but also ensures a secure and stable connection.

A D Sub connector, short for D-subminiature connector, is a type of electrical connector first introduced in the 1950s by ITT Cannon. Its name stems from its D-shaped metal shell, which provides mechanical support, ensures proper orientation, and offers some level of electromagnetic interference (EMI) protection.

For d-orbitals or d-subshell, Ɩ = 2, there are five values of m namely -2, -1, 0, 1, 2. It means d- orbitals can have five orientations. They have an even more complex angular distribution than the p orbitals. These are represented by d xy, d yz, d zx, d x2-y2 and d z2; for example, 3d xy, 3d yz, 3d zx, 3d x2-y2 and 3d z2.

Jul 10, 2024 · Selecting the appropriate D-sub connector involves referencing these standardized shell sizes to ensure compatibility with the device's specifications. It can be determined the primary shell size and gender type by examining the equipment requirements, streamlining the installation process.

Jan 5, 2021 · What does a D-Sub Connector look like? They are shaped like the letter “D,” with one side slightly longer than the other. Due to the shape, there is only one way to connect a device. All D-Sub connectors have a metal housing that surrounds two or more rows of male or female contacts.
