Hirose Electric FX18 Hi-Speed B2B Connectors

Hirose Electric FX18 Series Hi-Speed B2B Connectors are headers and receptacles, right angle or straight, with a 0.8mm pitch for coplanar or vertical 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). 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.

Features

0.8mm Pitch
Variations: Coplanar / Vertical
Number of Contacts : 40 / 60 / 80 / 100 / 120 / 140
Multi-functional contact (MF contact) as:
- Ground contact to enhance grounding
- Power supply contacts up to 12 A to reduce required pin counts
- 3-step sequential contacts for grounding and detection
Effective mating length of signal contact: 2.0 mm (MF contact A:2.5mm / MF contact B:1.5mm)
Large mating guide for easy mating

Pin through-hole mounting MF contacts increase strength against wrenching
Signal integrity
- Insertion Loss-to-Crosstalk-Ratio (ICR)
  - With five-aggressor differential FEXT meets the extrapolated IEEE802.3ap specification for 10+Gbps with plenty of margins
- Differential Impedance
  - The differential impedance is within 100±10 ohms at 35 ps rise time (20% to 80%)
