Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are common types of connections, found in a variety of different applications. The 91931-21169LF is an example of such an array, edge type, mezzanine rectangular connector. This connector is a key component for high performance electrical and controlled systems, featuring two rows of high power contacts for added reliability and performance in operation.

The 91931-21169LF is a board to board mezzanine connector, and is primarily used in industrial applications. This type of rectangular connector boasts an increased density in a small form factor, and is designed for applications regions with limited space but high voltage requirements. It is IP67 sealed for dust- and waterproof performance, as well as having high levels of vibration and shock resistance, making it suitable for outdoor and high-usage applications.

These connectors can handle wattages up to 17 amps per circuit, with a 2-row, 24-circuit arrangement. This helps to reduce the number of interconnections required within a system, making the finished system simpler and more reliable. There are two key contact styles available for the 91931-21169LF; FlipLock and BITE (Board Injection Touch Edge), both of which feature 4mm pitch connectors and are compatible with most standard PCB ranges.

As for the working principles of this mezzanine connector, the two main contact styles, FlipLock and BITE, differ slightly in their operation. FlipLock is the more commonly used contact style and operates by inserting two parallel contacts with block assembly and locking them into place. BITE, on the other hand, uses sequential injection with two different sets of mating features, such as cantilevers and guides, to ensure precise and reliable mating between the mating connectors. Additionally, the BITE contact style features a dual guide alignment system to ensure a successful connection, which is completed by a mechanical force.

In conclusion, the 91931-21169LF is a type of board to board mezzanine connector, offering increased density and reliability in high-reliability applications. This type of connector includes two separate contact styles, FlipLock and BITE, each with their own design principles and features designed to ensure reliable and efficient operation. Moreover, the 91931-21169LF is rated for wattages up to 17 amps per circuit, making it suitable for a variety of applications with unique electrical needs.
