Autonics, PRFDW Series
Stainless Steel Inductive Sensors- Cable Connector Type
PRFDW Series
The PRFDW series cable connector type cylindrical proximity sensors feature long sensing distances and full-metal housing and sensor heads 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 metal sensor head provides high resistance to impact and wear and the 360° ring type status indicator allows users to quickly identify operation status from various angles.

  • High resistance to impact and wear caused by contact with workpieces or wire brushes (sensor head/housing: stainless steel)
  • Reduced risk of malfunction caused by aluminum chips
  • Excellent noise immunity with specialized sensor IC
  • Built-in surge protection circuit and overcurrent protection circuit
  • Operation indicator (red LED), stability indicator (green LED)
  • 360° ring type status indicator
  • Oil resistant cable
  • IP67 protection structure (IEC standard)
  • closed-loop

    Full-metal Body Ideal for Application in Diverse Environments

    The entire sensor including the sensor head and housing are made of stainless steel 303, providing a robust design and high resistance to deformation, corrosion, and spreading of bacteria. The sensors are ideal for application in diverse environments including food and beverage manufacturing, chemical, and metalworking industries.


    Full-Metal Sensor Heads Provide Resistance to Impact and Wear

    The 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.


    High Resistance to Magnetic Field Noise from Welding Current

    PRFD(W) series full-metal inductive sensors feature high resistance to magnetic field noise from welding current.


    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 environments with metal debris.


    Oil-Resistant (PVC) Cable

    The robust oil-resistant cable allows the sensors to be installed in environments with hydraulic fluids or cutting fluids.


    Ring Type Status Indicator

    The 360° ring type operation indicator (red LED) and stability indicators (green LED) allow users to quickly identify operation status from various angles.


    IP67 Protection Structure

    The IP67 protection structure allows stable and error-free operation even in wet or dusty environments.



    PRFD series full-metal inductive sensors used to detect tray locations on food cleaning machines.
