3840-B-18P

Hirose Electric Co Ltd's 3840-B-18P 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 Plug 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 Multi-Purpose 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 18 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 Free Hanging (In-Line) 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 Solder 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.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.
