D-shaped connectors make up the most common type of connector used in computers and peripherals. D-shaped connectors are referred to as “Centronics,” and they have been around since 1970, when they were developed as part of the Xerox Alto personal computer.

The 71743-1044 connector, a Centronics type connector, is a “D” shaped right angle connector with an impedance matched pin-out. The connector features an offset-aligned D-shaped connector face, with 4, 5, or 6 pins arranged in a single row, and a secondary flat side that provides a direct connection to a mating double sided flat cable.

The 71743-1044 connector is a highly versatile device and is used in various applications ranging from computer peripherals, storage devices, digital audio interfaces, broadcast systems, and industrial instrumentation. In order to accommodate the different types of signals transported by these devices, the 71743-1044 can be configured with either a single-ended (SE) or a differential (DE) design.

The SE version of the 71743-1044 features two rows of pins that are arranged parallel to each other. The two rows of pins provide an impedance-matched signal path that allows for a low-loss transmission of electrical signals. The DE version of the 71743-1044 utilizes two separate and distinct pins for each signal path, which are typically arranged in a single row. The DE version also provides an improved noise immunity by ensuring that only differential signals are propagated through the connector.

The 71743-1044 is designed to provide secure and reliable connections between two mating components and is designed to withstand dynamic loads resulting from repeated plugging and unplugging. The connector is also the preferred choice when a low-inductance design is desired. High-frequency data transfer among devices is further improved by the fact that the 71743-1044 is designed to be thermally efficient.

In addition to its practical applications, the 71743-1044 is a common choice for the academic study of electronics. Thanks to its well-defined pin arrangement, the connector is a great introductory tool for understanding the fundamentals of electrical engineering. It is also commonly used as a teaching aid in courses covering signal propagation and transmission line theory.

The 71743-1044 is a rugged and reliable connector that is ideal for a variety of applications. Thanks to its impedance matched pin-out, it is an excellent choice for low-inductance designs seeking improved HF data transfer, while its thermally efficient construction makes it suitable for a wide range of operating temperatures. Additionally, it is a great introductory tool for the theoretical study of electronics, making it an invaluable asset both in the lab and in the classroom.
