Supplier's note

  1. Technical Breakthroughs:

    • Alloy Contacts: Triple the corrosion resistance of standard copper contacts, extending lifespan in corrosive environments.
    • Low-Profile Design: 20% thinner than industry benchmarks, enabling compact PCB layouts.
    • IP67 Waterproofing (Pro): Enables use in outdoor/wet environments without additional housing.

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial controls (e.g., HVAC systems) where 10A suffices.
    • Advanced Model: Choose for automotive or food-processing environments needing IP54 protection and wider temp tolerance.
    • Pro Model: Best for extreme scenarios like marine equipment or oil rigs, leveraging 20A capacity and IP67 submersion resistance.

With the Pro’s IP67 rating, you can deploy relays in outdoor pumps without additional enclosures. The Advanced Model’s expanded temp range ensures reliability in cold-chain logistics systems.
