Introduction to D-Sub, D-Shaped Connectors - Adapters

D-subminiature connectors, also known as D-subs, are electrical connectors that are mainly used in professional electronics applications, as well as in IBM PC compatible computers. The “D” term originates from the shape of the connector, with its two rows of pins looking like the letter “D”, so they are also called D-shaped connectors. The “Subminiature” term generally refers to the size of the wires used with them, as well as to the size of the combined electrical connector.

The D-sub connector comes in several different sizes and types, each offering different features and capabilities. The most common types are DB-9 standardized connectors, DB-15 connectors, DB-25 connectors, and HD-15 connectors. Each type is suited to specific applications, offering different connector configurations, number of pins, contact pitch, voltage ratings, wire gauge sizes, and more.

Application Field and Working Principle of 320X10549X

The 320X10549X is an adapter that converts the standard 15-pin D-subminiature connector to a DB-25 connector. This adapter consists of a DB-15 Female connector on one end and a DB-25 Male connector on the other end. This feature makes it extremely useful when connecting between two dissimilar connectors.

The adapter is designed to accommodate two 0.016 inch (0.4 mm) diameter contact terminals at a distance of 0.8 inch (20 mm). The total length of the adapter is 4.15 inches (105 mm) while the distance between the DB-15 and DB-25 connectors is 3.5 inches (89 mm). In terms of voltage rating, the 320X10549X can withstand up to 250 volts AC and 300 volts DC. The connector is also UL approved and meets the requirements of the IEC60884-1 standards.

In terms of the working principle, the adapter works by connecting the ground wire on the DB-15 Female connector to the DB-25 Male connector. This ensures that no electrical shock can occur when the two connectors are connected. In addition, the adapter also provides additional protection against leakage currents and static electricity.

Conclusion

The 320X10549X is a convenient and versatile adapter for connecting dissimilar connectors. Its small size and contact pitch make it suitable for a wide variety of applications. The adapter is UL approved and can handle up to 250 volts AC and 300 volts DC. Additionally, its design ensures that no electrical shock can occur when the two connectors are connected.
