D-Sub connectors are a common type of electrical connector used to attach two wires together. They are generally used as a permanent electrical connection between two devices, such as a computer and its monitor, or between two pieces of electronic equipment. The 191-025-113L551 D-Sub connector is a commonly used connector for these types of applications. This article will discuss the application field and working principle of 191-025-113L551 D-Sub connectors.

The 191-025-113L551 is a 25-pin, female D-Sub connector, with a black plastic shell and 2-56 UNC screws for mounting. It has gold-plated copper contacts and a standard spacing of 0.050 inches (1.27 mm). This D-Sub connector is commonly used for audio, video, and serial data connections between computers, monitors, and various types of electronic equipment. It is also popular for connecting interfacing boards, such as Video Graphics Array (VGA) and Peripheral Component Interconnect (PCI) cards.

Due to the 191-025-113L551’s mechanical robustness and high contact force, it can be used in a variety of application areas, including industrial control, medical equipment, telecommunications, automotive, aerospace, digital imaging, and consumer electronics. Additionally, it is a good choice for applications requiring higher levels of vibration, shock, and temperature exposure.

The working principle of 191-025-113L551 D-Sub connectors is relatively straightforward. It consists of two parts—a male and female connector. The male connector has protruding pins which fit into female sockets in the female connector. When the two halves are mated together, the contact surfaces, which are usually made of metal, make an electrical contact and completes the electrical circuit.

The 191-025-113L551 D-Sub connector is also designed for reliable mating and unmating, even when used in a harsh environment. It has a high contact force that ensures secure mating, and is capable of withstanding vibration, shock, and temperature extremes. Additionally, the contacts are gold-plated for maximum electrical performance and reliability.

In summary, the 191-025-113L551 D-Sub connector is a robust and reliable electrical connection solution for use in a wide variety of applications. Its gold-plated copper contacts ensure reliable electrical performance, while its mechanical robustness ensures it can withstand harsh environmental conditions. It is often used to connect computers, monitors, and other electronic devices together, as well as interfacing boards.
