84553-091

The 84553-091, commonly referred to as the edge connector, is an edge array type rectangular connector that is used to connect devices on a board. It has a two-part mating system, consisting of a “board side” and a “socket side” that provides a secure and reliable connection. These connectors are typically used to mount edge cards, such as memory modules, in electronic systems, and are often used in mezzanine board applications.

The 84553-091 includes a number of features designed to improve its performance. It is hot-molded using UL94-V0 rated material, which is resistant to fire and corrosion. Its high pin count, which reaches up to 84 positions, provides a reliable and secure connection between the board side and socket side. It is also designed to withstand temperatures of up to 200°C and includes an integrated bridge to reduce inductance. Additionally, the 84553-091 features a double wedge mating system, which helps to simplify the mating process.

The 84553-091’s working principle is based on its unique two-part mating system. This system enables the user to make a reliable connection between the two devices or boards, with minimal deformation. During the mating process, each part of the connector is lowered until it is fully engaged. The board side is then secured to the socket side, forming a reliable connection. The 84553-091 can also be used in applications where multiple boards need to be interconnected, as it is capable of accepting signals from multiple boards at once.

The 84553-091’s reliability and robustness make it an ideal choice for edge card applications. Its high pin count, resistance to temperature and fire, and integrated bridge make it a reliable solution for connecting multiple boards. Furthermore, its double wedge system simplifies the mating process, providing a secure and reliable connection. With its wide range of features, the 84553-091 can be used in a variety of applications, from mezzanine board to memory module connections.
