Abstract
This paper introduces a new sensor technology of analog or digital position sensor for the detection of a ferromagnetic target in rotary or linear motion. This sensor is based on the use of a permanent magnet exhibiting a specific shape; this magnet is associated to a conical ferromagnetic part. The presented sensor has an improved sensitivity due to the use of this conical ferromagnetic part (acting as a flux concentrator) associated to a permanent magnet.
