Tailored exclusively for new energy vehicle (NEV) battery systems, the JST ADHR-05V-S cable assembly delivers reliable power transmission and signal communication for battery management modules (BMS), battery cell modules, and on-board charging units. This 1.3mm pitch automotive-grade connector serves as a critical interface in electric vehicles (EV), hybrid electric vehicles (HEV), and plug-in hybrid electric vehicles (PHEV), ensuring seamless energy transfer and data feedback in harsh under-hood, chassis, and battery pack environments. Ideal for battery cell monitoring, voltage/current sampling, and BMS-ECU communication in space-constrained battery assemblies.
Technical Specifications & Superiority
Standard Compliance: Adopts JST ADHR series 1.3mm fine-pitch design (1.3±0.05mm pitch), 5-position single-row configuration compatible with AWG #24~#30 wires (conductor area 0.05~0.21mm²) and 1.6mm standard PCB thickness .
Enhanced Conductivity: Tin-plated phosphor bronze contacts with low-profile design ensure initial contact resistance ≤8mΩ and post-environmental test resistance ≤15mΩ, minimizing power loss in battery signal transmission .
Automotive-Grade Durability: Rated for 5A DC current and 300V DC voltage, with operating temperature range of -40℃ to +125℃ (meets NEV battery pack temperature demands). PBT GF15 housing (15% glass fiber reinforced) achieves UL94V-0 flame retardancy, resisting thermal deformation and battery electrolyte corrosion .
Secure Sealed Mating: IP67-rated waterproof/dustproof sealing structure prevents moisture, dust, and chemical ingress; integrated locking clip with tactile feedback ensures firm connection (≥500 mating cycles) and withstands vehicle vibration .
