Detailed Technical Specifications

Key Features & Operational Advantages

IP67/IP69K Waterproof & Extreme Environment Resistance

Our IP67 waterproof wiring harness is meticulously constructed to endure the most punishing operational climates imaginable, achieving up to IP69K industrial-grade protection. Featuring a heavy-duty sealing mechanism, it effectively blocks out high-pressure water jets, fine industrial dust, and corrosive fluids. The assembly thrives in extreme thermal conditions, maintaining peak flexibility and structural integrity across a wide temperature spectrum from -40°C to 125°C. This exceptional thermal and environmental resilience makes the 776164-1 connector harness an indispensable component for under-hood automotive compartments and exposed outdoor heavy machinery. By preventing moisture ingress and thermal degradation, this engineered solution drastically reduces the risk of short circuits, thereby minimizing unplanned downtime and lowering long-term maintenance expenditures for your fleet or facility.

Premium Pure Copper Conductor & Enhanced Electrical Performance

At the core of this automotive ECU wiring harness lies a meticulously stranded array of high-purity oxygen-free copper. This premium core material guarantees exceptional conductivity, safely accommodating a 250V voltage rating and a maximum current capacity of 17A without overheating. The low signal loss characteristics ensure that critical sensor data reaches the control unit instantaneously and without distortion. Our rigorous multi-stage quality control protocol encompasses incoming raw material verification, continuous in-process monitoring, and final 100% full functional testing for conductivity, insulation resistance, and voltage tolerance. This uncompromising approach guarantees that every single unit, whether part of a limited prototype run or a massive volume order, delivers identical, flawless electrical performance.

Mechanical Security & Global Compliance Standards

Physical security is just as crucial as electrical reliability. This harness integrates advanced mechanical safeguards, including Terminal Position Assurance (TPA), an intuitive integrated locking latch, and anti-mating keyway designs. These features provide a tactile, audible snap upon connection, completely eliminating the risk of accidental disconnection caused by severe, high-frequency vibrations or heavy impact shocks. Furthermore, the exterior is molded from high-strength PBT plastic paired with UL 94V-0 flame-retardant insulation, offering maximum fire resistance. As an IATF16949 certified wiring harness manufacturer, we ensure every 776164-1 wiring harness adheres strictly to international automotive safety protocols and environmental directives, providing you with absolute confidence in global supply chain compliance.
