VAC

VAC (Vacuumschmelze) is a German manufacturer headquartered in Hanau, Germany, known for its nanocrystalline and amorphous soft magnetic materials.

These materials form the core of its current sensors, including fluxgate-based designs, used where high accuracy and wide bandwidth isolated current measurement are required across industrial and high-precision applications.

In current sensors, they use advanced magnetic probe and amorphous field detector technologies to provide galvanic isolation, high linearity and low temperature drift.
