Application Field

The QFS-048-04.25-L-D-DP-PC4 is a high performance rectangular connector designed for creating reliable Board-to-Board connections. It offers low-profile design, which makes it ideal for use for applications with limited space. The connector also provides excellent protection against electrical noise thanks to its EMI shielding capability. It is often used for applications where signal transmission and data integrity are critical, such as network communications, storage, and machine vision applications.

The QFS-048-04.25-L-D-DP-PC4 operates at high speed and power levels, with its contact forces and contact retention forces ranging from 0.5 to 2.9 N, respectively. It also provides high current capacity that ranges from 3 to 24 A and a maximum operating temperature of up to 125°C. Furthermore, the connector offers a low and controlled impedance as well as excellent long-term reliability.

Working Principle

As part of the Edge Type, Mezzanine (Board to Board) category of connectors, the QFS-048-04.25-L-D-DP-PC4 is designed to allow two printed circuit boards to be connected together and separated easily. It works by providing a number of contact points between the two boards. These contact points are made up of two layers of contact elements that securely clip into one another. This ensures a secure connection between the two boards.

The contact force between the two boards is generated by a spring mechanism located between the contact elements. The spring mechanism applies a certain level of pressure on the contact elements, ensuring that a strong connection is always maintained between the two boards. Furthermore, the connector\'s contact retention force keeps the boards locked together, ensuring that the connection remains secure and reliable.

The QFS-048-04.25-L-D-DP-PC4 also offers excellent EMI shielding protection, which prevents any foreign signals from entering the connection and causing interference. This reduces the chances of signal distortion and data corruption, further enhancing the reliability of the connection.

Conclusion

The QFS-048-04.25-L-D-DP-PC4 is a highly reliable rectangular connector that is designed to provide Board-to-Board connections in tight spaces. It operates at high speed and power levels and is able to offer excellent long-term reliability. It also offers EMI shielding protection that prevents interference from outside sources. Finally, the connector works through a simple but secure mechanism of contact element clips and spring mechanisms that ensure a connection that is strong and reliable.
