91911-31551LF

Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) encompass a wide range of applications, with the 91911-31551LF model being a highly adaptable and reliable option. This article will discuss the application field and working principles behind this model.

Typical Applications

The 91911-31551LF is a board-to-board solution for commercial applications, such as handheld or core computing devices, as well as specific military and aerospace applications. It is an ideal option for medium to high-density applications as it provides flexibility in design and requires a very low profile for a board-to-board connectors. By utilizing standard mezzanine-edge pins, it allows for controlled impedance designs and a reliable electrical connection between the boards.

Key Features/Benefits

The 91911-31551LF has several key features that make it an ideal solution for a variety of applications. It boasts a ruggedized design, ensuring high reliability even in high vibration or contaminated environments. It also has an extremely low Z-axis profile that allows for tight packaging and minimal board real estate usage. Additionally, it comes standard with polarization keys for plugging accuracy and retention, and has a single-row to four-row design and contact pitches of 0.5mm and 0.635mm. The contacts are equipped with floating inserts and plating for enhanced board stability in the 1.27mm contact spacing range.

Working Principle

The 91911-31551LF requires a multi-step process in order to effectively power two boards. First, the plated contacts are aligned with the contact pins to ensure a secure fit between the boards. Then, the connector is locked in the correct position by the polarization keys. Finally, the electrical current is passed through the contact pins, which rests on the floating inserts. This process ensures that the two boards are closely connected by a reliable electrical connection.

Conclusion

The 91911-31551LF is a reliable and highly adaptable solution for a range of commercial and military applications. Its key features and working principles make it an ideal option for board-to-board connectors within tightly packaged enclosures.
