The Miniature Sensor Coil is a high-precision, compact inductive component designed for low-power, space-constrained sensing applications. Featuring a ferrite core, tightly wound high-purity copper wire, and a protective black epoxy coating, this coil delivers stable inductance, excellent magnetic permeability, and reliable signal response. Ideal for contact sensors, pulse detection, and small electronic projects, it converts magnetic flux variations into measurable electrical signals with exceptional accuracy.
