FAQ
Q: Can this sensor measure high-speed shafts?
A: Yes, it is suitable for high-speed rotation as long as the shaft material is ferromagnetic and meets the minimum diameter.
Q: Is it compatible with custom materials?
A: Ferromagnetic steel is standard; other materials can be accommodated on request.
Q: What is the recommended installation gap?
A: The sensor performs optimally with a 0.5 mm (20 mils) air gap from the shaft surface.
