FIELD: impulse engineering, in particular, devices for detecting approach of metallic controlling element, possible use for building machines with digital program control and automatic technological lines. ^ SUBSTANCE: in accordance to the invention, the core of inductance coil of LC-generator is formed by a set of U-shaped ferrite elements. Cross-sections of elements face one side and envelop the winding of inductance coil. Kernels may have varying length. Forming of various configurations of sensitive zone of sensor is ensured when typical ferrite elements are used. ^ EFFECT: simplification of design, reduced costs and increased distance of actuation. ^ 2 cl, 2 dwg
