Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

91911-21151LF Application Field and Working Principle

91911-21151LF is a type of rectangular connector used in arrays, edge type, and mezzanine (board to board) applications. This particular connector is a mezzanine connector, designed specifically for board-to-board connection, with a very low profile, allowing for tight fit and low inductance characteristics. The 91911-21151LF is suitable for high frequency and fast signal transmission applications.

The 91911-21151LF features a dual-row, 2-point contact configuration, allowing for a maximum current rating of 7.5A. It is equipped with an advanced locking mechanism, which provides an industry-standard coupled latching for secure connection, and ensures that the connector is robust and highly reliable. To further ensure contact connection, each 91911-21151LF connector is built with gold plated contacts in a dielectric with glass reinforced base, offering superior electrical performance.

In terms of physical structure, the 91911-21151LF connector has three components: a low profile mezzanine housing, with a height of only 6mm, two contact housing assemblies, and the contact lures. The contact lures are made of stamped phosphor bronze with gold plate, with reinforced cable tail. The gold plating enhances electrical and vibration resistance durability. The dual-row contact configuration gives the connector two points for electrical connection, making it suitable for array, edge type, and mezzanine applications.

The working principle of the 91911-21151LF is very simple. When the two contact housings are assembled to form a complete connection, the dual-row contact lures are securely fastened into each contact housing, allowing the connector to be used as a board-to-board solution. The contact lures then come into contact with the pads on the board to form a permanent electrical connection. This provides reliable electrical connections with minimal inductance, as well as consistent, reliable electrical performance for high frequency signals. It is also designed to provide a secure connection in severe vibrational environments, making it suitable for high-voltage and high-frequency applications.

The 91911-21151LF is widely used in a variety of industrial applications, such as electrical and electronic equipment, automotive, and telecommunications applications. It is also certified to RoHS compliance, making it an economical option for companies and organizations looking for high-quality, reliable connectors.

In summary, the 91911-21151LF is a type of rectangular connector designed specifically for board-to-board connection, with a very low profile, allowing for tight fit and low inductance characteristics. The unique dual-row, 2-point contact configuration enables a maximum current rating of 7.5A, while the advanced locking mechanism and gold plated contacts ensure reliable and consistent electrical performance. This connector is suitable for high frequency and fast signal transmission applications, making it an ideal choice for various industrial applications.
