Providing ±0.6 mm floating in X and Y axis, FX20 Series absorbs mounting misalignment from multiple stacking connectors and PCB shrinkage. Double beam contact structure provides shock and vibration resistance; each beam has unique vibration characteristic and contact force (0.5 and 0.35 N). Construction is resistant to sulfur dioxide, and operational range reaches 105°C. Parallel stacking and right-angle mating versions are available with 20–140 positions and range from 17.4–47.4 mm wide.
