AI Overview
Mu metal stacking cores are high-permeability, Ni80 (80% nickel-iron) permalloy laminations used to concentrate magnetic flux and shield sensors from external interference, particularly in Hall effect, current sensors, and clamp ammeters. These cores offer high accuracy, low hysteresis, and high sensitivity for high-speed current sensing.
Key Features and Applications
- Material: Composed of 80% nickel-iron alloy (Ni80) for high initial and maximum permeability.
