Overview

TE AUTOnet is a comprehensive family of high-performance, sealed electrical connectors specifically engineered for the harsh environments found in automotive and transportation applications. They are designed to meet and exceed the rigorous requirements of modern vehicles, especially as the industry shifts towards electric, hybrid, and increasingly data-intensive systems.

Key Applications

These connectors are used wherever reliable signal and power distribution is critical:

1. Powertrain: Engine Control Units (ECUs), sensors, transmissions.

2. Chassis & Safety: Braking systems (ABS/ESP), steering, airbag systems.

3. Body Electronics: Lighting, door modules, sunroofs, wipers.

4. Infotainment & Comfort: Displays, audio systems, climate control.

5. New Energy Vehicles (NEVs): Battery Management Systems (BMS), onboard chargers, inverters, electric motors, DC-DC converters.

   
   

Core Features & Design Philosophy

The AUTOnet system is built around standardization, robustness, and scalability.

1. Sealed and Unsealed Options:

   • Sealed Versions: Rated at IP6K9K (high-pressure wash) and IP67 (dust and temporary immersion). Crucial for under-hood and underbody applications.

   • Unsealed Versions: For protected in-cabin applications, offering cost efficiency.

2. Cavity Technology & Versatility:

   • Uses a modular, crimp-and-insert cavity system. Each cavity (the metal terminal housing) is independent.

   • Supports a wide range of wire sizes (0.13 mm² to 6.00 mm²) and current ratings (3A to 23A+) within the same connector family.

   • Can mix power and signal circuits in a single housing.

3. Connector Housing & CPA:

   • Made from high-temperature, chemically resistant plastics (e.g., PBT).

   • Features an integrated Connector Position Assurance (CPA) lock. This is a secondary locking device (usually a small slider or latch) that audibly and physically clicks into place when the connector is fully mated, preventing accidental disconnection from vibration.

4. Terminal Design:

   • Terminals are often tin or selective gold-plated for corrosion resistance and stable electrical contact.

   • The contact design ensures low insertion force and high normal force for reliable connectivity.

5. Tooling and Assembly:

   • TE provides a full suite of application tooling for precise, reliable crimping (crimpers) and insertion/removal (terminal positioners) of the cavities into the housing.

     
     

Common AUTOnet Series

TE has several sub-families within the AUTOnet brand, with the most prevalent being:

• AUTOnet 0.64 Series: The most compact, for signal applications (e.g., sensors).

• AUTOnet 1.5 Series: The industry-standard workhorse. Used for most sensor, actuator, and low-power module applications. Recognizable by its rectangular shape and orange CPA seal (on sealed versions).

• AUTOnet 2.8 Series & 4.8 Series: For higher power applications, such as small motors, heaters, or higher-current distribution.

  
  

Why are they so Widely Used?

• Reliability: Proven in billions of automotive applications over decades.

• Standardization: Many AUTOnet footprints (especially the 1.5 series) are de factostandards. This allows different suppliers' components to interface predictably.

• Scalability: Engineers can use the same connector family across an entire vehicle platform, simplifying logistics and tooling.

• Global Support: TE has a massive global manufacturing and engineering support network.

  
  

Comparison to Other Automotive Connectors

• vs. Deutsch (DT, DTM): Deutsch connectors are renowned in heavy-duty (truck, off-road, aerospace) and are often more robust and larger. AUTOnet is optimized for high-volume passenger vehicle cost and performance.

• vs. Sumitomo (HW, 090 series): Similar in philosophy and application to AUTOnet; both are Japanese/Euro-American 'origins' of major global standards.

• vs. Molex MX123: Another major competitor in the automotive space, with similar performance and sealing targets.

  
  

In summary, the TE AUTOnet connector is a foundational component in modern vehicle electrical architecture. Its success stems from a robust, sealed, and highly modular design that balances performance, cost, and reliability, making it a 'go-to' choice for automotive engineers worldwide.
