Electromagnetic induction-type absolute position transducer

摘要

A electromagnetic induction-type absolute position transducer according to the present invention has a plurality of scale loops functioning as coils. The scale loop has first and second loop portions and a connecting pattern portion which connects the corresponding first and second loop portions with each other. The first and second loop portions are arranged along the measuring axis at different wavelength intervals. At least part of the pattern widths constituting scale loops are gradually increased as the length of a connecting pattern portion becomes longer.
