FX27 Series, 0.8mm Pitch, PCIe Express Gen. 1 (2.5Gbps) High-Speed Transmission, Floating Card Edge Connector

HIROSE Electric Co. Ltd, a world-class manufacturer in connectors, has introduced the FX27 series of floating card edge connector, to support applications requiring PCI Express Gen 1 (2.5Gbps) high-speed transmissions.

The structure of the FX27 series features a flexible stacking height, dependent on the interposer PCB length. By using an interposer, a stacking height of 22mm (minimum) can be achieved. In addition, a wide self-alignment guide range of ±0.7 mm allows for easy mating in X and Y directions.

The FX27 provides the ultimate design flexibility with the option for designers to customize their original interposer printed circuit board with chip components.

A highlight of the FX27 series is that it can be used as a power connector, by using the entire surface of the interposer as a conductor for applications with good heat dissipation efficiency.

The floating structure offers a degree of play between the contacts during mating and allows the connector to absorb any alignment errors. The FX27 series provides a ±1.2mm floating with double floating in XY directions.

Furthermore, benefits from the floating function include the option of having multiple floating connectors used on the same PCB, connectors contribute to the device design by absorbing assembly errors which help to reduce the need for corrective re-work operations, and the spring portion of the terminal absorbs stress imparted by alignment errors. This reduces the stress applied to the mounted parts, which enhances reliability and prevents solder cracking.

FX27 series is part of the FunctionMAX product family. FunctionMAX consists of board-to-board connectors designed to meet the requirements of the industrial market with maximum functionality. FunctionMAX is designed based on a differential transmisson system and offers excellent noise resistance of high-speed signals.
