D-Sub connectors are a type of electrical connector commonly used in computer applications. The D-Sub connectors are named after their D-shaped metal shields. These shields have two opposing sides with a gap in between them. The two opposing sides form the “D” shape of the metal shield. D-Sub connectors are used to connect two electrical components, usually on a single computer board or in data transmission applications.

DBM21C1P1A9NA191K87 is a type of D-Sub connector designed for computer and data transmission applications. It features a male/female configuration allowing two different types of components to be connected. The connector comes with an array of 21 contact pins contained in a metal shield with two opposing sides. It has an outer diameter of 9mm and a total length of 19.1mm. The connector can be soldered both directly onto the board, or with a cable assembly for specialized applications.

The DBM21C1P1A9NA191K87 connector is used in a variety of applications. It is often used in USBs, keyboards, mice, gaming consoles, and other data transmission applications. It can also be used in computer motherboards for connecting expansion cards. It is highly reliable in data transmission, making it suitable for use in demanding applications.

The working principle of the DBM21C1P1A9NA191K87 connector is relatively simple. When two properly-matched D-Sub connectors are mated, the signal pins of each connector make correct electrical contact. This allows an electrical signal to be passed from one device to the other through the connection. The metal shield of the connector helps to reduce electromagnetic interference, adding to the overall reliability of the connection.

In conclusion, the DBM21C1P1A9NA191K87 connector is a type of D-Sub connector widely used in computer and data transmission applications. It features an array of 21 contact pins contained in a metal shield for improved reliability and EMI-reduction. When two properly-matched D-Sub connectors are mated, the signal pins of each connector make correct electrical contact, allowing an electrical signal to be passed from one device to the other through the connection.
