Introduction of D-Sub Connectors

D-Sub connectors, also referred to as DB9, DB15, and DB25 connectors, are common type of electrical connection used mainly in computers and communication applications. These connectors are used for data transfer between components such as digital devices, analog devices and computers. The type of common connectors may be quite diverse, from mini-D connectors, to micro-D connectors, to 9-pin, 15-pin, and 25-pin connectors. In addition, there are several cable packages for D-Sub connectors, including molded-in, color-coded connector shells, and machined or molded-in grounding or strain relief clips.

DBM21W1P1AFNK87 Application Field and Working Principle

The DBM21W1P1AFNK87 is a commonly used 9-pin D-Sub connector. This D-Sub connector is mainly used in the field of networking, communications, computers, and other consumer electronics, and is widely used in computers, electric vehicles, robots and other electronic products.

The working principle of this connector is that when the matching two connectors are inserted together, the side contacts of the two connectors are connected, forming an electrical connection, allowing for connection between two electronic components. Depending on the functionality required, different versions of D-Sub connectors can be used for either digital or analog signals. For example, the pins in this 9-pin D-Sub connector can be wired directly or through a cable. In either case, when the two components are connected together they will complete a signal circuit that allows data to be sent between them.

Conclusion

The DBM21W1P1AFNK87 is a 9-pin D-Sub connector that is commonly used in the fields of networking, communications, computers, and other consumer electronics. This connector works by forming an electrical connection between two components when the matching two connectors are inserted together. The pins in this connector can be wired directly or through a cable for either analog or digital signals. The DBM21W1P1AFNK87 is a versatile and reliable connection that is widely used in many electronic products.
