The FX18 series is a 0.8mm pitch, high-speed transmission connector that can handle 10 Gbps. Three different mating options highlight the versatility of this series. Multi-functional contacts can be utilized as follows: ground contacts, power supply contacts, or 3-step sequential contacts for grounding and detection. A large mating guide enables easy mating and helps to take advantage of Hirose’s effective mating length of 2.0mm for the signal contacts.
