Supplier's note

  1. Key Technical Breakthroughs:

    • Phosphor Bronze Contacts: Triple the fatigue life of standard brass, enabling 10,000+ connection cycles.
    • Nylon 66 Housing: 20% higher heat resistance than standard nylon, withstanding 125°C continuous use.
    • Spring-Lock Mechanism: Reduces contact resistance by 40% under vibration, ensuring stable power flow in automotive systems.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard consumer electronics (e.g., IoT devices) requiring basic durability.
    • Advanced Model: Choose for industrial sensors or medical devices needing enhanced vibration resistance and wider temperature tolerance.
    • Pro Model: Best for aerospace or heavy machinery applications where extreme currents (up to 4.5A) and corrosion resistance are critical.

With the Pro Model’s gold-plated contacts, you can achieve 99.9% conductivity in corrosive environments. Pair its industrial-grade vibration resistance with nylon 66’s thermal stability to create fail-safe connections in extreme conditions.
