AI Overview
Mu-metal stamped cores are high-permeability, nickel-iron (Ni80) alloy components used to concentrate magnetic flux and shield sensitive sensors from electromagnetic interference (EMI). These cores, typically 0.2mm to 1mm thick, enhance accuracy in Hall sensors, clamp ammeters, and current transformers by reducing parasitic magnetic fields.
Key Features & Applications
- Material: Comprised of Ni80 permalloy (approximately 80% nickel, plus iron and molybdenum) for high magnetic permeability and low coercivity.
- Manufacturing: Produced via precision stamping followed by annealing to restore magnetic properties.
- Applications: Essential in high-accuracy current sensors, ground fault circuit breakers, and magnetic shielding for, for example, drone magnetometers.
- Functionality: They act as flux concentrators in contactless current sensing, allowing for precise measurement of low currents while protecting sensors from external magnetic noise.
