Rectangular Connectors - Headers, Receptacles, Female Sockets, are designed to provide an electrically insulated or sealed interface between electrical components that can operate at higher voltages or currents. 89891-304H is one of the most popular products in this series. In this context, this paper will discuss the application field and working principle of 89891-304H.

89891-304H is a round shrouded male header. The shroud serves as a reference for the pcb when plugging in devices with different pin arrangements. The outside diameter is 11.43mm. It can be used to integrate various printed circuit boards together, and also can be used with common insulation displacement connectors. It is ideal for low-density connectors used in medical devices, automotive items, telecommunications and computer peripheral equipment.

89891-304H includes many features in its design. The product has gold-plated contacts, which ensures the assurance between the mated parts that it is a shielded connection. Additionally, the shrouded housing design is implemented to protect against debris, dust and other foreign debris that could potentially cut off the signal. This feature makes 89891-304H very versatile in harsh environment applications.

The working principle of 89891-304H is pretty simple. When the header connector is mated with the device, the shroud and pressure contact will hold it in place firmly. The connection will be secured by a positive input/output contact pressure that has been applied to the contact pads.The pins of the header are also designed to be in alignment with the pads on the board. When the header is shut, the pins will come in contact with the pads on the board, establishing an electrical connection. The spring-loaded design ensures that the contacts stay secure and do not loosen even in harsh environments.

Another useful feature of 89891-304H is its capability to support high-speed signal transmission as well as high-speed data switching. High-speed signal transmission in this connector is achieved through the use of multiple differential lines. The differential lines are designed to reduce crosstalk and improve signal integrity. This feature makes this product ideal for applications in test and measurement equipment and many other critical high-speed applications.

To sum up, 89891-304H is a high-performance, versatile, reliable and robust pin header connector.it is used to connect printed circuit boards together in both low and high voltage applications making it ideal for many different types of applications. It features a shrouded housing design to protect it from contamination and debris, as well as high-speed data switching and signal transmission capabilities. The contact pressure provided by the header ensures a secure and reliable electrical connection that will remain in place even in harsh environments.
