Supplier's note

  1. Three Breakthroughs:

    • Stainless Steel Construction: Outperforms plastic keypads by resisting corrosion in marine or chemical environments.
    • IP68 Water Resistance (Pro Model): Enables submersion in water, ideal for outdoor flood zones.
    • Enhanced Backlighting: The Pro Model’s 1500cd/m² brightness exceeds industry standards, ensuring visibility in direct sunlight.

  2. Version Selection Guide:

    • Base Model: Suitable for standard access control in offices or residential buildings.
    • Advanced Model: Choose for industrial workshops or warehouses with occasional water exposure.
    • Pro Model: Best for coastal facilities or outdoor kiosks requiring extreme durability. With the Pro’s IP68 rating, you can install it in flood-prone areas without system downtime.

With its metal dome contacts, you can ensure consistent tactile feedback even after thousands of presses. The RS485 protocol compatibility allows for longer cable runs than traditional RS232 setups, making it ideal for large-scale installations.
