D-Sub Connectors

D-Sub connectors are a type of electrical connector commonly used in computers for serial and parallel data transmission. Named for its “D” shape, a D-Sub connector typically consists of a hood, a mating backshell, a conductor, and a shell. The connector is used to connect various devices, such as printers, scanners, and TV monitors, with computers, making them an important part of computer external interface system. The features of D-Sub connectors includes durability, transmission performance, reliability, resistance to environment, and versatility.

204520-2 Application Field and Working Principle

The 204520-2 D-Sub connectors are commonly used for 8-bit serial and 4-bit parallel data transmission and operations. It is typically used on circuit boards due to its compact size. The 204520-2 D-Sub connector is designed with a 25-pin female connector, two rows of 19 pin contacts, and two shields. It has both a male and female version and typically is used in data transmission and serial applications. The 204520-2 connector is highly resistant to environmental conditions and provides an optimal signal transmission path for data transmission. The working principle of the 204520-2 connector is based on the insert/withdraw concept. When the 204520-2 connector is inserted into mating part, its contact pins are inserted into the female part and form an electrical connection. If the 204520-2 is withdrawn, its contact pins are separated from the female part, thus breaking the circuit.

The 204520-2 D-Sub connectors provide reliable data transmission in the most challenging environments. With its durable construction, it is designed to withstand harsh environment conditions, including direct sunlight, chemical exposure, and extreme temperatures. It also provides excellent insulation, easily ensuring that the signal is not interfered with or distorted. Its external shielding ensures that the signal is not blocked or disturbed by external noise and electromagnetic interference. Its low profile and the patented process guarantee a secure connection.

Using the 204520-2 D-Sub connectors in most applications provides a reliable and secure electrical connection. It has excellent mating characteristics and offers superior electrical performance. The 204520-2 is one of the most versatile connector types for connecting interfacing applications and provides a stable transmission capacity.
