NEW! Hirose has expanded its FX18 Series Board-to-Board connectors to include more contact sizes, lock types, and orientation styles (right angle and straight).The Hirose Electric FX18 Series Hi-Speed B2B Connectors are headers and receptacles, right angle or straight, with a 0.8mm pitch for coplanar, vertical, or stacking connection. The FX18 features high-speed transmission capability up to 10Gbps and multi-functional (MF) contact (ground contact, power supply contacts up to 12A, and 3-step sequential contacts).
