Scenario-Based Solutions


Automotive Manufacturing & Assembly

In automotive production lines, consistent and durable wire connections are critical to vehicle performance. This crimp terminal provides a plug-and-play solution for wire-to-board applications, streamlining assembly processes while meeting strict automotive industry standards. It integrates seamlessly with automotive connectors, ensuring stable power supply to sensors, lights, and electronic control units (ECUs), reducing the risk of connection failures and warranty claims.


Signal Transmission Systems

For automotive signal transmission—such as between navigation systems, infotainment units, and vehicle sensors—this terminal delivers low-resistance connectivity. Its tin-plated phosphor bronze construction minimizes signal loss, ensuring accurate data transfer even in high-vibration environments. It is particularly suitable for compact spaces, as its sleek design allows for dense packaging without compromising performance.


Aftermarket Automotive Modifications

Car enthusiasts and repair technicians benefit from this terminal’s compatibility with standard automotive wiring. Whether upgrading audio systems, installing LED lighting, or repairing faulty connections, the terminal’s reliable crimp design ensures a tight fit that resists loosening over time. It eliminates the need for soldering in many cases, saving time and reducing the risk of thermal damage to wires.


Product Features


Superior Conductivity & Durability: Constructed with phosphor bronze—a material known for high electrical conductivity and mechanical strength—with tin plating to prevent oxidation and corrosion, extending service life in harsh automotive conditions.

High Current Capacity: Rated for 6A maximum current (with a 40°C temperature rise) and 14V DC, making it suitable for both power and signal applications in automotive systems.

Secure Crimp Design: Engineered for a tight, vibration-resistant crimp that forms a permanent bond with 0.75mm² wire, reducing the risk of connection failure due to road vibrations or temperature fluctuations.

Active Status & Industry Compliance: Maintained in an active product status by Molex, ensuring ongoing availability and compliance with automotive industry standards for quality and safety.
