Supplier's note

  1. Technical Breakthroughs:

    • Capacitive Technology: Enables detection of non-metallic objects, expanding use cases beyond inductive sensors.
    • Extended Sensing Range (Pro Model): 10.4mm range surpasses industry standards by 30%, ideal for large-scale automation.
    • ATEX Compliance (Pro): Ensures safe operation in explosive environments, such as chemical plants.

  2. Optimal Version Selection:

    • Base Model: Suitable for standard automation tasks (e.g., conveyor belt sorting) requiring 8mm sensing in moderate environments.
    • Advanced Model: Choose for harsher conditions (e.g., cold storage) with expanded temperature range and RoHS compliance.
    • Pro Model: Best for hazardous zones (e.g., oil refineries) where ATEX certification and extended sensing are critical.

With a sensing distance of 8mm, you can achieve precise object detection in compact spaces. The Pro Model’s 30% longer range and ATEX certification enable safe use in explosive environments, while its low response time (0.7ms) ensures real-time feedback in high-speed systems.
