QFS-078-04.25-L-D-RF2 rectangular connectors are specifically designed for arrays, edge type, and mezzanine applications. A variety of different styles are available to accommodate a wide range of board-to-board interfaces, with solutions for vertical, end to end, and side-by-side connections. It is possible to support multiple levels of applications, from high-speed data communications to audio/video applications.

QFS-078-04.25-L-D-RF2 connectors are typically constructed from robust and vibration-resistant die-cast zinc alloy or stamped and formed phosphor bronze alloy. The contacts are made of brass material which is long-lasting, conductive, and resistant to wear and corrosion. Plugs feature a positive latching system for secure attachment.

The working principle of QFS-078-04.25-L-D-RF2 connectors is simple and straightforward. The connectors have two sections – male and female. The male section is equipped with a number of pins which, when correctly positioned, come in contact with the corresponding number of sockets present on the female section. This establishes an electrical connection between the two sections and allows signals to be transmitted between them.

The connection is secured by simply pushing a button on the male section, which releases a clamping mechanism and locks the two sections together. The locking mechanism is designed to resist vibrations, shock, and other external forces which may be applied to the connectors.

QFS-078-04.25-L-D-RF2 connectors offer a number of benefits, including stability, low crosstalk, low electrical losses, and lower installation costs due to the lack of an additional soldering process. Additionally, the connectors are cost-effective, reliable, and easy to install. This makes them ideal for a wide range of applications, including computer motherboards, backplanes, server boards, programmable logic controllers, and embedded computer systems.

In conclusion, QFS-078-04.25-L-D-RF2 rectangular connectors are designed to provide reliable and cost-effective solutions for arrays, edge type, and mezzanine applications. Their simple and straightforward design ensures a stable connection while also providing low crosstalk and electrical losses. Additionally, the connectors are easy to install and are suitable for a wide range of applications, making them the ideal choice for a variety of board-to-board connections.
