PRFDA Series

Description

PRFDA Series

Full-Metal Spatter-Resistant Long Distance Cylindrical Inductive Proximity Sensors (Cable Type)

The PRFDA series cable type spatter-resistant 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 spatter-resistant sensors are PTFE coated to reduce the risk of malfunction caused by welding spatter. 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. The sensors are available in Ø 8 mm, Ø 12 mm, Ø 18 mm, and Ø 30 mm sizes for easy installation in tight spaces and various other user settings.

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 Body Ideal for Application in Diverse Environments

    Food and Beverage

    The stainless steel 303 body minimizes the chance of bacteria spreading and the unibody design prevents cleaning agents or germicides from entering the sensor body.

  • Food and Beverage

    Chemicals

    The stainless steel 303 sensors are highly resistant to deformation and corrosion, which make it ideal for chemical applications.

  • Chemicals

    Metalworking

    The sensors are strong against impact and wear during metalworking applications and minimize the risk of malfunctions caused by welding spatter.

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

PRFDA(W) series spatter-resistant sensors feature high resistance to magnetic field noise from welding current.

  • PTFE Coating Prevents Malfunctions Due to Welding Spatter

    The non-stick PTFE coating prevents welding spatter from sticking on to the sensors which minimizes the risk of malfunctions during welding applications.

    PTFE (Polytetrafluoroethylene) Coating : A synthetic fluoropolymer of tetrafluoroethylene which has high heat resistance properties, low coefficient of friction, high abrasion resistance, non-stick properties, and excellent dielectric properties.

  • 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.

  • 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.

    except PRFDAT08-2DO-V model

     

  • IP67 Protection Structure

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

Applications
