The Shore hardness 60A material feels pliable yet forms an impenetrable barrier against moisture and dust. Internally, the connector interface relies on double O-ring seals crafted from premium silicone, creating a watertight vacuum that prevents any water ingress, even when subjected to direct high-pressure water spray (IP6K9K) during aggressive vehicle maintenance.
Strong Environmental Adaptability: Designed to outlast the vehicle's lifespan, the exterior materials resist severe UV radiation (verified by ASTM G154, 5000 hours of exposure). The rigid connector shells and secure latches withstand intense mechanical vibration (10-2000Hz, 4G acceleration) without loosening. Capable of operating flawlessly in extreme temperatures from -40℃ to 150℃, the harness also shrugs off corrosive oil pollution—including gasoline, diesel, and brake fluid—making it perfectly adapted for the harshest automotive operating environments, from the engine compartment to the undercarriage and door channels.
Reliable Quality & Durability: The core utilizes 99.9% pure copper cables, celebrated for their exceptionally low resistance and high conductivity. These are wrapped in premium insulation materials, including flame-retardant PVC rated at UL 94 V-0. Backed by strict testing and international certifications (IATF16949, ISO9001), the entire assembly is engineered to deliver long-term, maintenance-free durability, guaranteeing a reliable service life of ≥8 years or 200,000 km under constant daily use.
The internal cables are extruded from 99.9% high-purity oxygen-free copper, a material choice that ensures ultra-low resistance (resistivity ≤0.0172Ω·mm²/m) and highly efficient signal transmission, keeping CAN bus signal loss to an impressive ≤0.3dB/m. The outer insulation materials are carefully selected based on the deployment zone: flame-retardant PVC is utilized for general cabin areas (UL 94 V-0), high-temperature silicone rubber is deployed for engine compartments (resisting up to 200℃), and cross-linked polyethylene (XLPE) is used for areas requiring high-voltage tolerance. All variants provide exceptional dielectric insulation (breakdown voltage ≥25kV/mm) and remarkable physical wear resistance, enduring abrasion resistance testing of ≥2000 cycles without exposing the conductive core.
The male-to-female connector design is universally compatible with industry-leading automotive-grade brands, including Molex (Automotive Mini-Fit series), JST (PA series), TE (AMP MCP series), and Deutsch (DT series). The rigid connector bodies are injection-molded from high-temperature resistant PA66, capable of withstanding 180℃ for short periods without deformation. Inside, tin-plated brass contacts offer superior conductivity and corrosion resistance, easily passing the ≥500-hour salt spray test. To ensure maximum safety and error-proofing, the design integrates mechanical fool-proofing, intuitive color coding, and a high-strength locking mechanism (available in latch or threaded styles). This guarantees a locking force of ≥15N, entirely preventing accidental disconnection or reverse polarity insertion during severe vehicle movement.
