FAQ

Q1: Why use a stepped/tiered design for the core?

A: The stepped structure is designed to match the circular or elliptical space of coils more efficiently, reducing magnetic leakage and improving the precision of signal capture.

Q2: How does this core improve signal accuracy? 

A: By using grain-oriented (CRGO) steel, the core provides a low-reluctance path that concentrates the magnetic field, amplifying weak signals while filtering out electromagnetic interference (EMI).

Q3: Can you produce custom shapes based on my CAD drawings?

 A: Yes. We specialize in custom lamination and tiered core shapes to meet specific magnetic circuit requirements for various high-precision sensing applications.

Q4: Is this core suitable for high-frequency interference environments?

A: Yes, the high permeability and specialized lamination thickness effectively suppress eddy currents and external noise, ensuring stable signal output.
