Rectangular Connectors – Arrays, Edge Type, Mezzanine (Board to Board) include a variety of connector types designed for board to board applications. These types of connectors offer inexpensive and reliable solutions for popular applications such as telecommunication, computers, networking and industrial control. Among these rectangular connectors is the QFS-048-01-H-D-DP-RA-K, which is specifically designed for board-to-board applications. This section examines the application field and working principle of the QFS-048-01-H-D-DP-RA-K rectangular connector.

The QFS-048-01-H-D-DP-RA-K is a mezzanine two row board-to-board connector which consists of an interchangeable male and female header. The connector contains two rows each containing 48 contacts. This connector is suitable for high-speed digital signals and is rated to work up to 5.0GHz. Thus, this connector is well suited for board-to-board applications dealing with high frequency signal transmission, such as 10 Gigabit Ethernet applications, USB 3.0, PCI Express applications and other higher speed I/O applications. This type of connectors is also designed to provide a modular solution, allowing users to split larger boards into smaller modules.

The QFS-048-01-H-D-DP-RA-K is available in various contact designs, offering signal and power mating. The power mating includes a power contact which is capable of carrying up to 4.2A of current. The voltage rating for the power contact is VDC 50V. The signal contacts provide mating and retention of high frequency signals up to 5.0GHz at up to 10.6Gb/s data rate. Furthermore, the contacts include a built-in ESD protection feature which protects the signal against ElectroStatic Discharge (ESD) up to 8kV.

The QFS-048-01-H-D-DP-RA-K also provides extended mounting capability. The connector allows for vertical adjustment of the mounting height, allowing up to 8mm of height adjustment. Furthermore, it provides a secure and reliable connection, with a long term electrical connection stability. The connector housing is made of a high temperature thermoplastic, rated up to 125 °C. The contacts are gold plated and rated up to 1000 Mating Cycles.

The working principle of the QFS-048-01-H-D-DP-RA-K is relatively simple. The connector consists of a male and female header which mate together with snap-in latching for secure connection. The contacts of the male and female connectors are designed for a specific contact alignment, providing high reliability and signal integrity. When mated, the contacts of the male and female connectors are securely locked together. This provides a secure and long term connection which ensures signal integrity and prevents any loosening of the contacts.

In conclusion, the QFS-048-01-H-D-DP-RA-K is a high speed and high power board to board rectangular connector designed for applications dealing with high speed digital signal transmission. This connector offers a modular solution, allowing users to split larger boards into smaller modules. The connector provides extended mounting capability, a high temperature thermoplastic housing, gold plated contacts and is rated for up 1000 mating cycles. The working principle of the connector is relatively simple, with a snap-in latching system which provides secure and reliable connection.
