RC Board-to-Board Stackable Connectors

AirBorn / Molex RC Series Board-to-Board Stackable Connectors are low-profile bodied, high-density press-fit connectors. The series is available in 0.075" contact spacing and 100Ω and 85Ω differential serial buses. The high-density, press-fit connectors feature a patented female/compliant/male stacking contact system. The contact configurations are designed for signal integrity and trace design ease. AirBorn / Molex RC Series Board-to-Board Stackable Connectors feature BeCu contacts (high-conductivity, high-temperature alloy) and an eye-of-the-needle section design that eliminates soldering.
