QFS-052-04.25-H-D-GP

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

QFS-052-04.25-H-D-GP is an array form of edge type, mezzanine rectangular connectors. It is a type of cable assemble widely used in computing, audio and other electronic application. This type of rectangular connector provides reliable electrical connection and very low contact resistance.

Application Field

The QFS-052-04.25-H-D-GP is usually used in high speed I/O connection as a daughter card connection. It is also widely used in computing applications such as high speed data transfer link between servers and workstations. It is a very popular type of rectangular connector in applications such as industrial control and communication.

Working Principle

The working principle of this rectangular connector is based on the use of its two-levels contact arrays. The main element of the connecting solution is the array that has a wide range of contacts and an upper mating interface. The first level contains high-density pin-skirted contacts on a 90° pitch. The second level is composed of several vertical contacts placed on a 45°pitch.

When the pin-skirted contacts in the first level are inserted into the mating interface of the device, it ensures complete electrical contact between the two boards. The vertical contacts in the second level enable lossless connection operations between the two boards connection, such as power transfer and signal transfer. The QFS-052-04.25-H-D-GP also has a built-in grounding plate to reduce interference and ensure reliable signal transmission.

Conclusion

In summary, the QFS-052-04.25-H-D-GP is a widely used edge type, mezzanine rectangular connector with two levels of contact arrays. It is widely used in applications such as high speed I/O connection, computing applications, industrial control and communication. Its two-levels contact arrays enable a reliable connection between two boards by providing both low contact resistance and complete electrical contact. The integrated grounding plate also reduces interference and ensures reliable signal transmission.
