High-frequency electromagnetic fields emitted from the 8 mm tip induce eddy currents on the target shaft surface, modulating the carrier signal proportional to physical air gap distance.\u003c\/p\u003e\n\u003cp\u003eThe associated driver unit continuously evaluates static DC voltage levels for precise gap voltage validation, targeting standard nominal operating points around -10 VDC.
