PRFD Series - Full-Metal Cylindrical Long-Distance Inductive Proximity Sensors
PRFD Series Full-Metal Cylindrical Long-Distance Inductive Proximity Sensors
The PRFD series cylindrical proximity sensors are available in standard and IO-Link communication models. The sensors feature long sensing distances and full-metal housing and sensor heads made of stainless steel 303. The robust sensors provide high durability and can be applied in diverse environments including food and beverage manufacturing, chemical, and metalworking industries. The status indicator offers users to quickly identify operation status from various angles.
Main features

Various Connection Types
Available in Various Sizes and Cable Types
The sensors are available in M8, M12, M18, M30 size models, and cable/cable connector/connector types allowing installation in tight or limited spaces and various other user settings
Easy Maintenance with IO-Link Communication (IO-Link Model only)
IO-Link communication models feature detection of abnormalities in sensors such as over-access, unstable, disconnection detections for convenient maintenance. IO-Link Master is required for IO-Link communication and IODD file can be download from our website.
Full-Metal Sensor Heads Provide High Durability
The stainless steel 303 sensor heads provide high durability, making the sensors ideal in environments where the sensor heads can be worn due to workpieces or wire brushes.
Except for ø8mm model.
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.
Status Indicator for Quick Identification
Operation indicator and stability indicators allow users to quickly identify operation status from various angles. IO-Link communication models provide communication status.
Green LED : Stability, Communication / Orange or Red LED : Operation / Green, Orange LED : Malfunction

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 PRFDA□ Models
Normal operation even in short installation distance between sensor and welding area (10 mm front, 50 mm side installation)
Minimum distance is for M18 models, and 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.
