The 91901-31211LF array is a popular edge-type rectangular connector, designed to facilitate easy connection between boards in mezzanine applications. The technology behind this connector is incredibly simple yet effective. A vertical array of posts provides a direct connection between boards with minimal interference, resulting in high performance connections.

The 91901-31211LF array features a set of posts arranged in a vertical line along the vertical plane of the board. Each post in the array has a single pin at its tip. This single pin is the only contact made with the target board, providing reliable contact values at all times. The distance between the posts in the array varies depending on the connector size, but typically posts are spaced at 2.54mm centers. This spacing ensures good contact and provides a robust connection, allowing for the safe and reliable transfer of signals between boards. Additionally, this spacing prevents any signal interference between adjacent pins, which can cause data transmission errors.

The 91901-31211LF array also utilizes specially designed edge connectors to insure uninterrupted signal transmission. These connectors are designed to slide neatly onto the board and provide even, secure contact at all times, without accidental detachment. The resulting configuration ensures that the board-to-board connection will remain reliable and secure for extended periods of time, making it perfect for use in mission-critical application scenarios.

The 91901-31211LF array is a popular choice for mezzanine applications due to its simple yet effective design. Its vertical array of posts provides a direct connection between boards, while its edge connectors ensure that the connection remains reliable and secure. Additionally, its spacing between posts prevents signal interference, resulting in high performance. As such, it is a preferred connector choice in mission-critical scenario applications.
