Product details
Optimized for automotive electronics, the 1837940000 from Weidmüller sets new benchmarks in Terminal Blocks - Headers, Plugs and Sockets reliability. This AEC-Q200 qualified solution addresses the unique challenges of electric vehicle power distribution systems while ensuring signal integrity in harsh automotive environments.The Header, Male Pins, Shrouded (4 Side) configuration incorporates automotive-grade sealing for under-hood installations. Compared to commercial components, it provides IP6K9K protection against dust and high-pressure washdowns.Available in 21 positions, the design supports 48V mild hybrid architectures. The dual-row arrangement minimizes voltage drop in high-current battery connections.21 positions per level optimize packaging density in ECU applications. The staggered contact pattern reduces mutual inductance between adjacent power and signal lines.The 1 stacking capability enables three-dimensional wiring harness routing. This approach reduces cable bulk by 30% in door and roof lining applications.Featuring 0.200" (5.08mm) pitch spacing, the design prevents tracking in high-humidity conditions. The creepage distance exceeds LV214 requirements for 600V systems.Vertical options facilitate PCB integration in space-constrained modules. The right-angle versions minimize Z-height for under-seat electronics.The Solder system ensures vibration-resistant connections meeting USCAR-2 standards. Accelerated life testing confirms performance beyond 25G vibration profiles.Through Hole installation satisfies automotive module mounting requirements. The anti-rotation features prevent loosening under vehicle vibration spectra.Meeting 27.5A IEC standards, the design accommodates regenerative braking currents. The mass-termination capability supports automated harness production.The 400 V certification includes testing for partial discharge in high-voltage systems. The design exceeds 800V requirements for electric vehicle powertrains.Rated for 18.5 A continuous current, the contacts employ automotive-tested alloys. The material selection prevents stress relaxation in high-temperature engine compartments.The 300 V rating includes 150% design margin for load dump scenarios. The insulation system withstands 1000V transients per ISO 7637-2.The Black housing incorporates automotive OEM-specific color coding. The UV-stable material retains color fidelity after 3000 hours of xenon arc testing.Operating across -50°C ~ 100°C range, the materials meet extended automotive temperature profiles. Validation testing includes 1000 thermal shock cycles from -40 C to 150 C.Tin plating provides optimal performance for automotive electrical systems. The surface treatment resists fretting corrosion in vibration environments.The Mating and Mounting Flange include automotive-specific safety interlocks. These prevent accidental disconnection during vehicle operation while enabling quick service disconnects.
