Introduction to The D-Sub Connectors

The D-Sub connectors are one type of electronic connection interface commonly used in the industry. They are versatile, reliable, easy to install, and able to accommodate a variety of connection scenarios. The D-Sub connector is popular for its reliability, convenience, low cost, and wide range of applications. A D-Sub connector typically includes an external metallic shell, a set of contacts that can provide power, signal, data, and other services, and an internal insulating material. Additionally, the connectors are usually equipped with threadlockers that secure the external shell and its contacts, ensuring a long-lasting secure connection.

Common Types and Applications

There are multiple kinds of D-Sub connectors, each provided with its own range of benefits and uses. The most common types are:

• DB-9: This type of connector is commonly used in PC keyboards and mice, as well as offering an Ethernet connection to digital audio/video equipment.
• DB-15: these connectors are either used to connect a mouse to a personal computer as an alternative to the DB-9 connector, or in the connection of parallel port devices.
• DB-25: this type of connector is mainly used in connection of printers, pointing devices and serial ports.
• DB-37, DB-50, DB-62, and DB-78: these connectors are commonly used for industrial control systems.
