Magnetic field-dependent, inductive proximity switch

摘要: A magnetic field-dependent,inductive proximity switch, consisting of a high frequency oscillator with coil and core, an evaluation circuit which determines the oscillation amplitude as function degree saturation core and, when specific limit value is reached, triggers process. The consist, for example, ferrite posssesses yoke-like body. Th switch makes it possible to have smaller sensor design shapes, higher sensitivity, enables manufacture at advantageous price by use soft material body such that permeability curve, related quadrant co-ordinate system, has pronounced S-shape.
