140°C floating connector resists vibration and misalignment in vehicle ECUs
The FX26 series from Hirose are board-to-board connectors for high-temperature environments. A floating structure decouples board movement, supporting reliable stacking near heat and vibration sources.
The Hirose FX26 series are floating board-to-board connectors with strong vibration resistance, providing high reliability when used in automotive systems that experience substantial mechanical stress.
The connectors have two-point contacts using materials rated for 140°C operation so that connection is maintained close to hot components. The connectors, with ±0.7mm float in X and Y directions, and ±0.75mm tolerance in the Z direction, provide tolerance for the assembly process on the production line. The design also prevents misalignment during mounting, keeping installation simple, even when visibility is limited.
A range of mated heights and pin counts allows one connector family to serve multiple designs.
