QFS-078-02-H-D-RA-K Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

Application Field

The QFS-078-02-H-D-RA-K is an edge-type mezzanine connector designed to connect two printed circuit boards in a 3-row by 8-column array. It features a combination of row and column contacts which extend from the outer edges of the connector and mate in a face-to-face configuration. This design also allows for the connection of multiple layers of board-to-board connections. This makes the QFS-078-02-H-D-RA-K a perfect choice for applications in data storage, networking, and medical systems, as well as any situation that requires multiple board connections.

Working Principle

The QFS-078-02-H-D-RA-K is an array-type miniature connector with a height of only 4.56mm. It has a pitch in the X-axis of 2.54mm and a pitch in the Y-axis of 5.08mm. The QFS-078-02-H-D-RA-K has an operating temperature range of -55°C to +125°C and a voltage rating of 500VAC.The QFS-078-02-H-D-RA-K comes with multiple rows and columns of board-to-board connections. Each contact is a combination of row wall plugs and column pins. The row wall plugs are supported by a plastic housing which holds and positions the contacts in place. The column pins have a contact area on their ends which mate with the row wall plugs when the connector is mated. All contacts are gold plated for better conductivity and corrosion resistance.When two connectors are mated, the column pins are pushed inside the row wall plugs. The contact area on the column pins then contacts with the wall plugs, creating an electrical connection. The contact area on the column pins also ensures the wall plugs stay in place and remain in contact. The connector is held in place by 2 locking latches which secure the connector to the board. The latches are released by a latch release button which is located on the side of the housing.The QFS-078-02-H-D-RA-K also has EMI shielding to prevent the interference from external EMI sources. The shielding is a metal alloy which helps shield the contact beams from any kind of interference. This shielding also adds to the strength and durability of the connector.

Conclusion

The QFS-078-02-H-D-RA-K is a perfect choice when you have multiple board connections. It is a versatile and reliable product with great features such as the row and column contacts and the EMI shielding. This connector is ideal for applications in medical systems, data storage, and networking.
