The QY2036A/B is built for high-frequency professional use. While standard cables often suffer from signal degradation or loose connections over time, this OBDII extension cable for cars is rated for over 10,000 insertion cycles. Whether you are extending a port for easier access or protecting your expensive diagnostic scanner from repeated wear, these cables deliver the stability required for modern automotive service.

Elite Hardware & Signal Integrity

• High-Conductivity Copper Core: Built with 26AWG oxygen-free pure copper wiring, tin-plated to prevent oxidation and ensure rapid, lag-free communication between the ECU and your diagnostic tool.

• Reinforced Aluminum Foil Shielding: Includes a specialized shielding layer that provides superior anti-interference protection, blocking electromagnetic noise for clean and accurate data transmission.

• Industrial Durability: Precision-molded connectors are designed to maintain a secure, "click-fit" connection without deformation, even after years of daily use in a busy shop.

• Flame-Retardant Insulation: Wrapped in environmentally friendly, flame-retardant material, providing an essential layer of safety in high-heat engine or cabin environments.

• Flexible Length Options: Available in 36cm and 56cm variants to accommodate various dashboard layouts and reach hard-to-access diagnostic ports.

Professional Service Applications

• Port Protection (Port Saver): Acts as a permanent extension to take the physical wear of daily plugging and unplugging, preserving the vehicle’s original factory OBDII port.

• Ergonomic Maintenance: Allows technicians to relocate the diagnostic connection to a more comfortable position, enabling live data monitoring from the driver's seat or beside the vehicle.

• Stable Data Logging: The superior shielding makes it ideal for performance tuning and mobile data logging where signal stability is critical for catching intermittent faults.
