Supplier's note

  1. Three Breakthroughs:

    • Zinc Alloy Housing: 20% lighter than traditional metals, reducing system weight while maintaining corrosion resistance.
    • IP69K Waterproofing: Triple the pressure resistance of standard IP67 connectors, enabling use in heavy-duty automotive washdowns.
    • Dual-Lock Mechanism (Pro): Combines threaded and bayonet locks for 40% faster assembly than single-lock designs.
  2. Optimal Version Selection:

    • Automotive Engineers: Choose the Pro Model for IP69K protection and high-temperature tolerance in engine compartments.
    • Industrial Automation: The Advanced Model balances cost and performance for robotics in factories.
    • General Electronics: The Base Model suffices for indoor PCB assemblies with standard environmental exposure.

Example Benefit: With the Pro’s dual-lock mechanism and IP69K rating, you can ensure secure, long-term connections in agricultural machinery exposed to dust, moisture, and extreme vibrations.
