PRF Series - Cylindrical Inductive Full-Metal Proximity Sensors

PRF Series Cylindrical Inductive Full-Metal Proximity Sensors

The PRF series cylindrical proximity sensors feature full-metal housing and sensor head made of stainless steel 303. The robust sensors are highly resistant to deformation and corrosion and can be applied in diverse environments including food and beverage manufacturing, chemical, and metalworking industries. The 0.8 mm thick metal sensor head provides high resistance to impact and wear and the 360° ring type operation indicator allows users to quickly identify operation status from various angles.

Thick 0.8 mm Metal Sensor Heads Provide Resistance to Impact and Wear

The thick 0.8mm metal sensor heads provide strong resistance to impact and wear, making the sensors ideal in environments where the sensor heads can be damaged or worn due to workpieces or wire brushes.

Except for ø8mm model.

  • Impact Resistance
    • Stable impact-resistant head structure against continuous shock
    • Initial appearance of the new product head

      Initial state

    • Unchanged head shape after 150,000 impacts

      After 150,000 cycles

    • Head operating normally even after 300,000 impacts

      After 300,000 cycles
      (Normal operation)

    Sensors can be used safely even in harsh operating conditions without risk of damage to the sensor heads.

  • Wear Resistance
    • Wear-resistant head structure strong against brush abrasion
    • Initial appearance of the new brush head

      Initial state

    • Brush wear condition after 30 minutes of continuous use

      After 30 minutes

    • Head operating normally even after 3 hours of continuous use

      After 3 hours
      (Normal operation)

    Sensors can be used safely even with the wear on the sensor heads caused by continuous wire brush use.

  • Reduced Risk of Malfunction Caused by Aluminum Chips

    The sensors are designed to minimize the risk of malfunction due to aluminum chips, offering high performance in environment with metal debris.
