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

Rectangular connectors represent a broad class of interconnects with a variety of applications in different industries. These connectors serve the purpose of connecting electronic devices, and thus ensuring efficient communication between them. The 91901-31431LF is an example of a rectangular connector, specially designed for mezzanine (board to board) applications.

What is a 91901-31431LF Application?

A 91901-31431LF application is a type of mezzanine, or board-to-board, connector. It is a surface mount of a rectangular connector, with up to 9 positions which make it suitable for numerous applications. It is commonly used for wired networks, telecommunication systems, HVAC systems, and industrial systems. It is also suitable for other types of connections, such as with motor controllers, power supplies, and analog signal distribution.

Features/Benefits of 91901-31431LF Applications

• Durable and reliable connection between boards.
• Ideal for dealing with multiple cables and applications.
• Easy to connect multiple boards as the contacts are already prewired.
• Tin plated contacts ensuring corrosion resistance.
• High dielectric strength up to 2 KV DC.
• Temperature range up to -40°F (-40°C).
• High speed transmission rates up to 6Gbps.

91901-31431LF Working Principle

The 91901-31431LF comprises of several parts that ensure the reliable connection of two boards. It is composed of a receptacle and a header. Both are soldered on one side of a circuit board and have eight “fingers” that allow connection between the receptacle and the header. The receptacle contains several “pins” that make contact with the “fingers” of the header. The “pins” are generally made of copper and feature tin plated contacts.

The connection between the receptacle and the header is based on a “clamshell” design, meaning that the header is inserted into the receptacle, which holds it in place. The connection is secured by dual screws, which are tightened to the receptacle and the header. This ensures that the contact is reliable and secure.

When two boards connected via the 91901-31431LF are integrated into a system, they will be able to exchange signals at high speed, with low contact resistance (due to the tin plated contacts). The temperatures and electrical stresses sustained by the 91901-31431LF connector make it a suitable option for many industrial applications.

Conclusion

Whether it is for an industrial system, a communication system, or any other type of system, the 91901-31431LF is a reliable, secure, and high-performance mezzanine connector. It is durable, easy to install, and provides a low contact resistance. It is an ideal solution for board-to-board connection applications.
