Hirose’s 0.8mm pitch board-to-board high-speed card edge FX27 Series connector allows for varying board stack heights by simply changing the length of the PCB interposer.

Additionally, the FX27 Series features an increased XY axis floating range compared to previous high-speed FunctionMax family connectors. Now supporting a floating range of ±1.2 mm in both the X and Y directions, the FX27 Series board-to-board connector absorbs stress from misalignment while tightening screws and PCB shrinkage caused by high temperatures. The card edge connector also has a wide self-alignment range of ±0.7 mm in both the X and Y directions. The floating contact and self-alignment design eases the assembly process providing time and cost savings, especially when mating multiple connectors on the same board.
Supporting PCI Express Gen 1 interface standard, the FX27 Series offers data transmission speeds up to 2.5Gbps. When used as a stacking connector, the FX27 Series stacking height, wiring and component mounting are customizable. A conductor to transmit power with flexible height adjustment is also available. The FX27 Series operates in environments from -55 to 105ºC, including the temperature rising by current flow and delivers a 0.5A current per pin capacity.
