Abstract
A proposal is made for an inductive sensor device which consists of an electric coil and an assigned core which is arranged in a housing consisting of a ferromagnetic material and is likewise produced from a ferromagnetic material. For the purpose of detecting angular positions or changes in angle of rotating machine parts, in the device the coil is arranged on a rectangular coil former (form) which is provided at its centre with an elongated cutout (opening) extending in the direction of its longitudinal axis. The housing opening assigned to the cutout is of a length and width which roughly correspond to the length and width of the cutout, and the core is designed as a configured plate and is assigned to the cutout or the housing opening via a rotating part which is aligned at right angles to the plate and mounted eccentrically thereon.
