PRF Series

Full-Metal Cylindrical Inductive 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.

Available in Various Sizes and Cable Types

The sensors are available in M8, M12, M18, M30 size models, and cable/cable connector types allowing installation in tight or limited spaces and various other user settings.

 

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

Initial state
After 150,000 cycles
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

Initial state
After 30 minutes
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.

 

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 Operation Indicator (Red LED)

The 360˚ ring type operation indicator allows users to quickly identify operation status from various angles.

*Except for ø8mm model.

 

IP67 Protection Structure

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

High Durability in Welding Environment

Full-metal inductive sensors feature high resistance to magnetic field noise from welding current and the non-stick PTFE coating prevents welding spatter from sticking on to the sensors which minimizes the risk of malfunctions during welding applications

*Spatter-Resistant PRFA□ Models

Normal operation even in at 10 mm front installation and 50 mm side installation. (M18 models)
*Minimum distance may change depending on welding environment
*Protection cover sold separately
*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.

Applications
