SENSOR DEVICE AND FUEL INJECTOR WITH A SENSOR DEVICE

The invention relates to a sensor device (30; 30a) for detecting the movement of an element (27), comprising a device (50) for generating an electrical voltage, wherein the device (50) has at least one magnet element (51) and at least one coil element (59; 65, 66) arranged movably relative to the magnet element (51) and cooperating with the magnet element (51), wherein the magnet element (51) is fastened to a first support element (31) and the at least one coil element (59; 65, 66) is fastened to a second support element (32), wherein the two support elements (31, 32) each have a fastening area (39) for fastening to a support component (11) with respect to a direction running perpendicular to a longitudinal axis (42) of the at least one coil element (59; 65, 66) on opposite sides of the at least one coil element (59; 65, 66), wherein the two support elements (31, 32) are elastically deformable in an area between the fastening areas (39), and wherein, upon deformation of the support elements (31, 32), the position between the magnet element (51) and the at least one coil element (59; 65, 66) changes.
