FX27 Series High-Speed Card Edge Connectors

Hirose's FX27 series card edge connectors for use in a wide range of industrial and automotive applications

Image of Hirose's FX27 Series High-Speed Card Edge Connectors Hirose's FX27 series 0.8 mm pitch board-to-board connectors allow for flexible stacking heights by simply changing the length of the printed circuit board (PCB) interposer, eliminating the need for different height connectors. The FX27 connectors feature 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 the Y directions, these connectors absorb stress from misalignment while tightening screws and PCB shrinkage caused by high temperatures.

The FX27 series high-speed card edge connector also has a wide self-alignment range of ±0.7 mm in both the X and the Y directions. The floating contact and self-alignment design ease the assembly process, providing time and cost savings, especially when mating multiple connectors on the same board. A friction lock on one side ensures the interposer board is retained on the desired connector when unmating. Supporting PCI Express® Gen 1 interface standard, this series offers data transmission speeds up to 2.5 Gbps. When used as a stacking connector, their stacking height, wiring, and component mounting are customizable. A conductor to transmit power with flexible height adjustment is also available.

The board-to-board connector's double beam contact design offers self-cleaning functionality. The first beam eliminates dust from the contact path, securing an ultra-reliable contact path for the second beam. The contacts on both receptacles are enclosed in a housing, which provides advanced protection against dust. This feature also reduces the risk of dust adhesion due to solder waste and flux during the mounting process.

The FX27 series operates in environments from -55°C to +105°C, including the temperature rising by current flow, and delivers a 0.5 A current per pin capacity. The recommended PCB layout is 60 positions for mounting, interposer, and cut out designs. In addition to industrial and automotive environments, this series is designed for a wide range of applications including base stations, servo drives, servers, servo motors, cash registers, ultrasonic diagnosis equipment, PLCs, and more.
