The present invention relates to an injection device (100) for determining the axial position of at least one device member (12; 212; 30) of an injection device (100) inside a housing (102) of the injection device (100). ), The sensor device (10) is located inside the housing (102) and extends in the axial direction (1, 2) and has a different magnetization and in the axial direction (1, 2). An elongate member (12, 212) having at least a first section (12a; 212a) and a second section (12b, 12c, 12c; 212b, 212c, 212c) separated;-first and second The axial position of at least one of the sections (12a, 12b, 12c, 12d; 212a, 212b, 212c, 212d) And at least one magnetic sensor element (22.1, 22.2, 22.3) attached to the housing (102). |
