QFS-016-04.25-H-D-DP-A

The QFS-016-04.25-H-D-DP-A connector is one type of rectangular connectors within the arrays, edge type, mezzanine family. This edge type type of connector provides high reliability in a mezzanine configuration, allowing high-volume applications to gain the benefit of high-bandwith data throughput. It is designed with mechanical compliance and increasing data-density catered to fit specific interconnection requirements.

In the application of these connectors, the body of the unit is made up of a two-piece plastic housing construction, separated by a flat metal contact. The ground terminals are then positioned at the four edges of the contact strip, with the contact termination area facing downward. The electrical contact is made through a standard contact made of gold-plated phosphor-bronze.

Then come the application fields and working principle of the QFS-016-04.25-H-D-DP-A connector. It is designed to be commonly used in data transmission systems requiring reliable connections, such as factory automation, office automation, medical instruments, communications products, audio and video equipment, and consumer electronics. Due to its small size and lighter weight, it can be adopted in tight spaces with limited space. It also works effectively in high-volume applications due to its 50-pin size and the ability to interconnect between two self-aligned connectors with a significant contact force that maintains a good electrical connection.

The QFS-016-04.25-H-D-DP-A connector offers a working principle that is suitable for mated and unmated applications. It is a self-aligning connection system that is designed to ensure an extremely reliable connection between two pins. The contact area is designed with two contact points on each contact pad, one being a "Free Geometry" point and the other being a "Support Geometry" point. Once mated, these two points create a secure electrical connection, while the "Free Geometry" provides the frictionless self-aligning feature.

The contact points of the QFS-016-04.25-H-D-DP-A connector are also designed to be entirely isolated from each other. This ensures a stable signal transfer with high precision, accuracy and minimal losses. The connector also provides outstanding performance, with its high contact force and mechanical stability. It also excels in EMC and RFI protection performance owing to its combination of shielded housing and gold-plated contacts.

In addition, due to the contact strip being angled towards the outside of the connector, it ensures that pressure on the contact is uniform and reduces the risk of contact damage.

In conclusion, the QFS-016-04.25-H-D-DP-A connector is a multi-functional edge-type mezzanine connector, suitable for a wide range of applications. It is designed for 50-pin size and has a self-aligning connection system to ensure a secure electrical connection. The isolated contact points further improve the electrical performance, while its EMC and RFI protection performance is also exceptionally good. Other beneficial features of the connector include its uniform contact pressure, high contact force and mechanical stability, light weight and portability, and lower risks of contact damage.
