This JST SFH series automotive internal connector cable combines the SFH-0017-P0.5 terminal pins with the SFHR-02V-L 2-position housing, creating a reliable 1.8mm pitch interconnect solution specifically designed for lithium battery systems in vehicles. Engineered for low-profile, high-current applications, it delivers stable power transmission for automotive internal electrical systems with a space-saving 3.0mm height design, secure friction locking, and robust construction to withstand harsh automotive environments, ideal for connecting lithium battery packs to vehicle control modules, BMS (Battery Management Systems), and other electronic components.
Key Features & Advantages
Ultra-Low Profile DesignAt just 3.0mm height, this connector enables significant space savings in crowded automotive battery compartments and internal wiring channels, perfect for modern electric and hybrid vehicle designs.
High Current-Carrying CapacitySupports up to 4A per circuit (with AWG #22 wire), providing ample power for lithium battery charging and discharging applications while maintaining efficient energy transfer.
Secure Friction Locking MechanismIntegrated friction lock prevents accidental disconnection from vehicle vibration, ensuring stable connections in dynamic operating conditions. The housing includes anti-inversion guides to prevent incorrect mating.
Automotive-Grade DurabilityTin-plated copper terminals resist corrosion and oxidation, while the high-temperature housing material withstands extreme temperature fluctuations (-40°C to +85°C) and chemical exposure common in automotive environments.
Side-Entry MatingUnique side-entry design allows for easier installation in tight spaces, simplifying wiring harness assembly and maintenance access in vehicle battery systems.
Precision Crimp TechnologySFH-0017-P0.5 terminals feature a contact lance with spring action for secure retention in the housing, ensuring consistent electrical performance and high pull-out force, meeting strict automotive quality standards.
