QVR-105
Automotive Wiring Harness: Reliable, Flame-Retardant Interior Wiring Solution for Modern Vehicles The QVR-105 Automotiver Wiring Harness is a high-performance, industry-compliant electrical assembly engineered for automotive interior applications. Designed with precision and durability in mind, this wiring harness supports both 30VAC and 60VDC systems, making it ideal for modern vehicle electrical architectures that demand consistent power delivery and safety compliance. Compliant with ROHS standards and featuring flame-retardant PVC insulation, the QVR-105 meets stringent global safety requirements while offering exceptional flexibility and ease of installation. Key Features This automotive wiring harness includes tin-coated copper conductors ranging from 0.2 to 10mm² cross-sectional area—ideal for low-voltage control circuits, lighting, sensors, and infotainment systems. The bare-copper option ensures superior conductivity, while the tin-plated variant enhances corrosion resistance and solderability. With a temperature rating of 105°C (105C), it performs reliably under extreme conditions found in engine compartments or cabin environments. Its T8139-certified flame-retardant design reduces fire risk in case of overheating, ensuring passenger safety and regulatory adherence. Detailed Description Manufactured using premium-grade materials, the QVR-105 harness integrates robust connectors, strain relief mechanisms, and color-coded wires for simplified diagnostics and maintenance. Each conductor is individually insulated with flame-resistant PVC sheathing, minimizing electromagnetic interference and preventing short circuits. The easy-strip feature allows technicians to quickly prepare wire ends without specialized tools, reducing labor time during vehicle assembly or repair. Whether used in OEM manufacturing or aftermarket modifications, this harness delivers long-term reliability and minimal signal degradation over its operational lifespan. Applications Commonly deployed in passenger cars, SUVs, and light commercial vehicles, the QVR-105 serves as a critical component in dashboard wiring, door modules, climate control systems, and instrument clusters. It’s particularly suited for electric vehicle (EV) interiors where stable low-voltage connections are essential for battery management systems and onboard electronics. Its versatility extends to hybrid vehicles, autonomous driving platforms, and advanced driver-assistance systems (ADAS), where consistent electrical performance is non-negotiable. Customer Feedback Users praise the QVR-105 for its consistent performance across diverse climates—from Arctic cold starts to desert heat exposure. One professional installer noted, “The tin-copper construction makes stripping and crimping effortless, even in tight spaces.” Another engineer highlighted the flame-retardant properties: “In our lab tests, the harness maintained integrity longer than competing models when exposed to controlled ignition sources.” These testimonials reflect real-world validation of its engineering excellence. Frequently Asked Questions
What does 105C mean on this harness?
It indicates the maximum continuous operating temperature the harness can withstand—up to 105 degrees Celsius—without degrading insulation or conductor performance.
Is this harness suitable for high-current applications?
While optimized for low-voltage circuits (up to 60VDC), it supports currents up to 40A depending on wire gauge, making it ideal for control and signaling rather than motor-driven systems.
Can I customize the length or connector types?
Yes, OEM and bulk buyers may request custom configurations based on vehicle specifications, including terminal type, cable length, and routing style.
How does it compare to other flame-retardant harnesses?
Unlike generic alternatives, the QVR-105 uses certified T8139-rated materials and meets international automotive standards such as ISO 16750 and SAE J1453, ensuring superior fire resistance and mechanical resilience.
