Introduction of D-Sub Connectors

D-sub connectors are a family of electrical connectors which use either the DE or DB type of shells. These shells are made from metal and have a rectangular cutout into which the connector is inserted. D-sub connectors are available in various types which include the male-female, male-male, and female-female types. D-sub connectors are typically used for serial data transfer, although they are also used in industrial automation, telecommunications, and other applications.

749879-5 Application Field and Working Principle

The 749879-5 D-sub connector is a 9-pin female-to-female connector. The 749879-5 is a straight through connector which means that when two 749879-5 connectors are mated together, the contacts of one connector are connected to the corresponding contacts of the other connector directly. This allows the 749879-5 connector to be used in applications where straight through serial data transfer is required, such as in serial communications.The749879-5 connector has a maximum rated current of 3.0A and a maximum rated voltage of 250V. It is suitable for use in temperatures ranging from -25°C to +85°C and an operating force of between 10N and 20N. The contacts are made of copper alloy and are gold-plated for superior electrical contact and corrosion resistance. The shell of the 749879-5 connector is made from zinc-plated steel and is black-painted for further corrosion resistance and protection.The 749879-5 connector can be used in a wide variety of applications, such as data transfer between computers, digital cameras, network connections, and in industrial automation and control systems. It is also suitable for use in telecom systems, gaming consoles, and for cable connections between electronic devices.

Conclusion

The 749879-5 D-sub connector is a 9-pin female-to-female connector which is suitable for applications requiring a straight through serial data transfer. It has a maximum rated current of 3.0A, and a maximum voltage rating of 250V, and is suitable for temperatures between -25°C and +85°C. The contacts are made of gold-plated copper alloy and the shell is made of zinc-plated steel. The 749879-5 connector is suitable for use in serial communications, network connections, digital cameras, industrial automation, gaming consoles and more.
