DEU9P

Introduction to D-sub Connectors

D-sub connectors are a type of mating hardware used in computer and communication applications. D-sub connectors are used as a means of connecting parallel and serial cable assemblies. The most common type of connector is the D-subminiature, or D-sub, which is used in a wide variety of applications, from data storage, networking, and gaming peripherals to war gaming and industrial control systems.

DEU9P Application Field and Working Principle

DEU9P is a type of D-sub connector, also known as DE-9P or DE-9. It is a 9-pin d-sub connector commonly used for parallel input/output (PIO).

DEU9P is most commonly used for parallel port connection on PC systems. Its small size makes it suitable for use in places where there is limited space. The DEU9P is also used to connect devices such as printers, scanners, and modems.

The DEU9P connector consists of 2 rows of pins, each row containing 4 pins and a central ground pin. The cable connectors are designed to fit into the DEU9P socket, which is fitted onto the circuit board of the device. The pins have a differential impedance of 150 ohms, which helps reduce electromagnetic interference (EMI) and crosstalk.

The DEU9P connector is typically soldered to the circuit board, with the cable connected using crimp pins. The cable is designed to provide the necessary electrical connections between the circuit board and the DEU9P connector. The two rows of pins are designed to mate, with the necessary resistance, in order to prevent a short-circuit from occurring.

Conclusion

In conclusion, the DEU9P is a versatile and reliable connector used in a wide range of applications. Its small size makes it suitable for use in tight spaces, and its low impedance helps reduce EMI and crosstalk. Its robust construction and reliable electrical connections ensure reliable and stable data transfers.
