Proximity sensor with improved positioning accuracy for detection coil peripheral members |
摘要 |
A proximity sensor according to the present invention includes protrusions that are provided on a wire-winding drum of a coil spool around which a lead wire of a detection coil is wound, that protrude toward the center from not less than three points distributed in the range exceeding a semi-circle on the circumference of the wire-winding drum and that are elastically brought into contact with the shaft of the core, respectively, thereby coaxially positioning the coil spool and the shaft of the core.
