UE78-B2127-00321

Amphenol ICC (Commercial Products)'s UE78-B2127-00321 delivers automotive-grade performance in the Pluggable Connectors category, specifically designed for next-generation vehicle networks. This robust connectivity solution meets stringent AEC-Q200 requirements while enabling high-speed data transmission in electric vehicle battery management systems.The Receptacle with Cage, Ganged (2x2) architecture incorporates vibration-resistant features for automotive environments. Receptacle-with-cage versions demonstrate 3x better retention force than commercial equivalents in 20G shock tests, ensuring reliable operation in autonomous driving sensor clusters.As a SFP interface leader, this connector supports automotive Ethernet protocols. Multi-Purpose variants accommodate both 100BASE-T1 and 1000BASE-T1 standards with identical footprints, simplifying ECU design across vehicle platforms.With 80 (20 x 4) contacts, the connector optimizes hybrid power/signal distribution. 24-position versions support 12A power contacts alongside 16 high-speed data lanes, ideal for integrated zone controllers in software-defined vehicles.Engineered for Through Hole, Right Angle installation challenges in vehicles, the connector features IP67-rated seals when mated. Board-edge configurations save 25% space in tight instrument panel cavities while maintaining >500N cable retention force per LV214 standards.The Press-Fit system ensures reliable connections in temperature-cycling environments. IDC versions maintain <10m contact resistance change after 1000 cycles (-40 C to +125 C), outperforming solder joints in engine control module applications by 4:1 margin.Board Guide, EMI Shielded address unique automotive requirements. Flange mounting provides 360 shielding continuity for CAN FD networks, reducing EMI emissions by 15dB at 500MHz compared to unshielded alternatives in EV powertrain systems.Gold selection meets automotive durability needs. Tin-plated contacts with nickel barrier layers prevent fretting corrosion in door module applications, demonstrating <5m resistance change after 50,000 vibration cycles.Precision 30.0µin (0.76µm) ensures long-term reliability. The 0.80 m gold-over-nickel variant shows <2% wear after 25 mating cycles - critical for maintenance-free operation throughout a vehicle's 15-year service life.
