D-Sub Connectors: DDMM43W2PF179A Application Field and Working Principle

D-Sub connectors are used for a variety of applications where dependent power and signal connection between 2 electronic circuits are needed. These connectors are used to provide interconnection between two pieces of electronic equipment such as computer peripherals, embedded boards, or for backplane applications. The DDMM43W2PF179A is a common D-Sub connector that is designed to enable a wide range of application fields, as well as providing high flexibility and cost effectiveness.

Application Fields

The application fields of DDMM43W2PF179A includes modem connection, fax connection, parallel port connection, serial port connection, printer port connection, and many more. It is also widely used in the medical industry, as well as in data communication and in electric measurement systems. In general, the connector is used to provide reliable connections between two devices that require both data and power signals to operate.

Working Principle

The DDMM43W2PF179A connector of D-Sub type has a particular design where the male and female contacts have a microscopic depth of penetration. This contact arrangement ensures a reliable electrical connection of low contact resistance, which is also quite stable even under high vibration and shock conditions. The contact could be made with a simple coupling action that is easy to perform, or with a screw-on or solder-on method.

The male contacts are designed with a particular “V” notch, which is made up of two lips. This ensures that the male and female connectors are precisely mated with each other in such a way that no mix-up between multiple lines can occur. The DDMM43W2PF179A also comes with a variety of additional features like integrated grounding, high contact density, and a variety of voltage and current ratings.

Conclusion

In conclusion, the DDMM43W2PF179A is a common connector type of D-Sub type that is widely used in various application fields. The connector provides a high degree of flexibility combined with cost-effectiveness, and it also features a secure electrical connection with low contact resistance. Additionally, with the right coupling action, the connector could also be used to provide reliable power and signal connection between two electronic circuits.
