Supplier's note

  1. Technical Breakthroughs:

    • Inductive Technology: Enables non-contact detection, reducing mechanical wear.
    • Metal Housing: Offers superior resistance to shocks and corrosion compared to plastic enclosures.
    • Dual Output Configurations: Simplifies system compatibility without external adapters.

  2. Optimal Version Selection:

    • Base Model: Suitable for standard industrial environments (e.g., conveyor belts, basic robotics).
    • Advanced Model: Ideal for harsher conditions (e.g., food processing, outdoor machinery) with extended temperature ranges.
    • Pro Model: Best for high-vibration or extreme environments (e.g., automotive assembly lines, mining equipment).

With the Pro Model’s IP69K rating, you can ensure operation in high-pressure washdown scenarios. The Advanced Model’s +50% faster response time compared to Base models reduces latency in real-time systems. Choose NPN/PNP outputs to align with your control system’s voltage requirements.
