D-Sub connectors are multipurpose electrical hardware components which are used for connecting two or more cables together. They have standardized configurations, with various categories based on the number of pins or contacts per connector. The 5748440-2 is a nine-pin “D-sub” connector, commonly used in the electronics and telecommunications industry for connecting computer peripherals such as keyboards and mice. Its application field and working principle are explained in this article.

Application Field

The 5748440-2 D-sub connector is most commonly used to connect computer peripherals such as keyboards, mice and scanners. It is also used in RS-232 serial data communications, and is often present in modems, sound cards, hard drives, and other computer peripherals. Other applications include controlling factory automation machinery, controlling communication equipment, sensing, measuring, and other diagnostic equipment for medical or industrial purposes.

Working Principle

D-sub connectors have two sides: the male side consists of a plug with pins that fit into receptacles in the female side of the connector. Each pin is a copper contact that is connected to a wire in the cable. When the plug is inserted into the socket, the pins on the plug make physical and electrical contact with the receptacles in the socket. This connection creates an electrical connection between the two cables, thus allowing the transfer of signals between them.

The 5748440-2 is a nine-pin, gold-plated D-sub connector. The nine pins are arranged in rows, with the center row of pins being the largest. The physical dimension of the connector is 22.38 mm in length, with a 10.36 mm width. The contact resistance is 0.2 ohms or less and the insulation resistance is 1000 megohms or more.

Conclusion

The 5748440-2 D-sub connector is one of the most commonly used types of connectors in the electronics and computing industry. It is used to connect computer peripherals such as keyboards, mice and scanners, as well as for serial communication protocols such as RS-232. Its nine pins are arranged in rows and the connector is gold-plated for improved signal transmission. The connector is also highly reliable and has a contact resistance of 0.2 ohms or less and an insulation resistance of 1000 megohms or more.
