D-Sub connectors, such as the 747548-2, are widely used due to their reliable design and secure connection. Most common applications of the studied series are found in computers, instrumentation, telecommunications, and other industries needing reliable, quick-connect solutions. Furthermore, these connectors offer a wide range of combination options and accessories to ensure perfect adaptability to specialized conditions.

The 747548-2 is a type D, single-ended, male/male connector. It is constructed of tin-plated stainless steel, making it mechanically robust and suited to high-frequency applications. In addition, it has a gold-plated contact base, which ensures low electrical exchange during connection. The connector is designed to accommodate cable sizes of 2.1mm-2.5mm with 5 and 638 plugs, respectively. The rated current is 3 A, and the rated voltage is 250V AC.

The working principle of the 747548-2 is relatively simple. It consists of two contact pins arranged in a row. The mating contact pin is inserted into the back side of the connector and held in place by the internal springs. As the mating contact pin is inserted, a friction lock is created between the two pins secure the connection. This connection is further secured by the use of additional screws, nuts, and clips which are screwed onto the connector. The contacts are then permanently joined and cannot be separated until the screws and nuts are unscrewed.

The working principle is complemented by the features offered by the connector. Notable features include dust protection, EMI shielding, LED indicators, multipoint contacts, and the ability to withstand a high degree of vibration and shock. The connector is also designed to prevent dust and other contaminates from entering the connection, ensuring the reliability of the connection. Finally, the LED indicator allows any potential user to easily identify a properly connected cable and provides visual feedback for any user troubleshooting a connection.

In summary, the 747548-2 connector is designed for use in a wide range of applications. Its robust construction and reliable connection make it suitable for challenging applications such as computers, telecommunications, and instrumentation. Furthermore, its features such as dust protection and EMI shielding enhance its performance and ensure its reliability. Finally, the LED indicator ensures users can easily identify and troubleshoot any potential connection problems.
