Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

The QTH-040-01-L-D-DP-RA is a rectangular connector specifically designed as an array of edge-type, mezzanine connectors for connecting two boards directly. Mezzanine connectors are a type of board-to-board connectors that are typically used in applications which require higher data rates, finer pitched features, and greater density. Mezzanine connectors are most commonly used for connecting boards or components at perpendicular angles.

Application Field

The QTH-040-01-L-D-DP-RA is ideal for high-speed applications with data rates up to 5.0 Gbps and features 2mm pitch (centerline), 12 by 14 pins, and 28 total positions. It is designed to meet a wide range of application needs and is compatible with multiple modern bus communication standards such as Serial ATA (SATA), Multi-Lane SAS, and USB 3.0.

The mezzanine cable is semi-flexible, suited for tight bend radii where bend angles are typically less than 90°. The small form factor makes it ideal for use in limited space applications such as servers with high board stacking density and for enclosure-less designs.

It also has a low profile, suitable for high-density, high-current, high-reliability environments, such as industrial, medical, and communications applications. The durable construction with stainless steel sheet metal makes it resistant to wear and corrosion, allowing for repeated mating cycles.

Working Principle

The QTH-040-01-L-D-DP-RA utilizes conductive features to mate two boards directly, without cables or wires. This direct mating strategy helps eliminate space, cost, long wiring runs, and potential signal loss. It features two differential pairs, twelve signal, and two power contacts, with open-end contacts that ensure secure mating each time.

The connector offers a sacrificial tab, which slides open when an access terminal is being inserted, and then clicks back into place once it is fully engaged. This allows the connector to remain securely in place in the end product design, while allowing for easy removal if required.

In addition, the QTH-040-01-L-D-DP-RA features a keyed alignment insulator and a raised groove, which are designed to provide added security when mating during board-level connection. The keyed alignment helps ensure secure mating, resulting in reliable connections for board-level interconnects.

Conclusion

The QTH-040-01-L-D-DP-RA is a rectangular connector specifically designed as an array of edge-type, mezzanine connectors for connecting two boards directly. It is ideal for high-speed applications with data rates up to 5.0 Gbps. It features 2mm pitch (centerline), 12 by 14 pins, and 28 total positions and is compatible with multiple modern communication standards such as Serial ATA (SATA), Multi-Lane SAS, and USB 3.0. It has a low profile and is suited for high-density, high-current, high-reliability environments, with its durable construction and stainless steel sheet metal making it resistant to wear and corrosion.

The direct mating strategy helps eliminate space, cost, long wiring runs, and potential signal loss and the keyed alignment and raised groove offer added security when mating during board-level connection. This ensures reliable connections for board-level interconnects and allows for easy removal of the connector.
