The new FX26 series from HIROSE

The new FX26 series from HIROSE - Floating Board-to-Board Connectors up to 140°C for high vibration

Floating Board-to-Board Connectors up to 140°C for high vibration

HIROSE Electric has successfully developed a high contact reliability connector with a -40 to 140℃ operating temperature that maintains the highest performance in vibration environments, including on-board powertrain. The new FX26 series maintains high contact reliability even in temperatures ranging from -40 to 140℃ and under severe vibration.



High heat and vibration relief performance required



While the shift to hybrid cars and EV (electric vehicle) is gaining momentum worldwide, the motors and inverters used in these eco-cars are always subject to problems of heat generation and vibration. In addition, the lifespan of a car, which was said to be 10 years and 100,000 kilometers, is increasing rapidly, so vehicles need to be able to be operated safely for a long period of time. Therefore, automotive connectors must also be tough enough to withstand the high heat and vibration conditions of powertrains for long time spans.

A unique floating structure solves the problem of contact failure caused by vibration. FX26 is a small, easy-to-assemble connector with outstanding performance in vibration environments.



Board-to-Board Floating Connector with Vibration Isolation Structure "FX26":



  • Thermal shock test at -40℃ to 140 ℃ and 3,000 cycles cleared to confirm heat resistance
  • Pass severe vibration conditions for equipment installed in the engine room, such as inside the inverter
  • 1mm pitch, low height, space-saving, contributes to sets downsizes


The newly developed FX26 can meet the requirements of powertrain control systems for existing electric vehicles and hybrid vehicles.
