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). With a large mating guide for smooth insertion, the Hirose Electric FX18 Series Hi-Speed B2B Connectors mate with a signal contact of 2.0mm and offer a voltage rating of 100V_AC. MF contacts are phosphor bronze with gold-plated contact area and mounting area and nickel-plated under plating.
