Mezzanine connectors are essential components in a variety of electronic devices and are becoming increasingly popular due to their versatility. In this article, we will discuss the QMS-052-05.75-L-D-A-RF2 mezzanine connector and its application field and working principle.

QMS-052-05.75-L-D-A-RF2 is a mezzanine connector, which is designed to effectively connect two boards together with a robust rectangular array of contact points. It is a type of edge connector that includes two opposite sides of contacts that interconnect two PCBs (Printed Circuit Boards) at right angles. It features high-frequency performance with an impedance of 50 ohm. This mezzanine connector is of very fine pitch, with features a contact pitch of 0.0575mm (0.00230in.).

Typically, mezzanine connectors are used in applications where two PCBs need to be connected in a very dense way. QMS-052-05.75-L-D-A-RF2 is highly suitable for applications such as board stacking on FPGAs, cellphone designs, multimedia systems, and LCD panels. This connector is also suitable for high-speed digital communication applications like Ethernet, USB, Serial ATA, and HDMI.

The working principle of this mezzanine connector is simple yet effective. It features two ascending arrays of contacts with a metallic barrier between them. The connector has a robust metal plated housing, which provides effective insulation and allows the two sides of the connector to be securely locked in place. The two sides of the connector are typically mated with a sliding type of motion, allowing for very precise and secure connections.

The contact points on the connector are arranged in an “X” pattern. This ensures that the perfect connection is always made when mating the two PCBs. Furthermore, this type of design is very tolerant of misalignment and vibration. The contacts of the connector are gold plated, providing excellent electrical performance with minimal contact resistance.

Overall, the QMS-052-05.75-L-D-A-RF2 is a reliable and versatile mezzanine connector and is suitable for many applications. It offers high-performance connections in a robust and secure design. This type of mezzanine connector is well-suited for board-to-board connection applications, where quick and reliable connections need to be made.
