53309-2691

The 53309-2691 is a high-density mezzanine connector, employing a rectangular array and an edge type format in its construction. Specifically designed for board-to-board applications, the 53309-2691 is an incredibly versatile connector offering a variety of interconnect solutions. It is widely employed within a variety of industries, including mobile computing, networking, aerospace, defence, and industrial.

Basic Construction

The 53309-2691 consists of two mating parts: a plug and a receptacle. The plug is typically mounted on a single-sided circuit board and incorporated within the cable assembly. The receptacle is fixed on a double-sided circuit board. The two parts engage via an array of contact points.

The contacts are arranged in a square depressions in the plug and a complementary square pedestal on the receptacle. The number of contacts varies depending on the requirement, though typically the connector is available with between 4 to 22 contacts. Similarly, depending on the application, the contact finishes may be soldered or crimped.

Platform

The design of the 53309-2691 allows for maximum flexibility, as it can accommodate a number of mating interfaces, impedances, and design requirements. Both the receptacle and the plug are available in various configurations, including various heights, lengths, and components. Therefore, the connector can accommodate a number of application-specific requirements, including stack height, pitch, and array size.

The 53309-2691 has an ample contact area, which ensures reliable mating. Furthermore, the connector features a robust mechanical design, with the components reinforced against vibration. The product is designed to withstand up to 5G shock and 2G or less of an operating environment.

Application Usage

The 53309-2691 is particularly well-suited to certain applications, though it is widely employed across a number of industries. Its robust and reliable design makes it suitable for use in many applications which require a reliable and secure connection. One such application is in the field of mobile computing, where the product’s ability to withstand vibration and shock is highly valued.

In addition, the 53309-2691 is a frequent choice for networking applications, where a reliable and secure connection between different components is essential. The connector is also used in challenging environments, such as aerospace and defence, as its vibration and shock resistance make it suitable in both static and dynamic applications.

Working Principle

The working principle of the 53309-2691 is extremely straightforward. Upon insertion, the contacts are forced downwards into their pedestals. This creates a reliable connection and ensures a secure mating. Furthermore, the 53309-2691 can be designed to handle a wide range of temperatures, making it suitable for both hot and cold environments.

Notably, contact force increases with increasing temperature levels and the design allows for superior temperature expansion and contraction. Moreover, a variety of contact finishes can be employed to ensure an even more reliable connection in harsh environments.

Conclusion

The 53309-2691 is an extremely versatile mezzanine connector, offering an effective board-to-board connection in a variety of applications. Its attractive design allows for flexibility in a range of configurations, while its robust construction ensures reliable and secure connections. Notably, the connector is widely employed in challenging industries, such as mobile computing, networking, aerospace and defence.
