PRF Series - Full-Metal Cylindrical Inductive Proximity Sensors
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.
Main features
- 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
- 360° ring type operation indicator (red LED) (except M8 models)
- Oil resistant cable
- Protection structure: IP67
- PTFE coating prevents malfunctions caused by welding spatter (spatter-resistant models)

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 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.
