Axial position sensing device for piston in hydraulic clutch in motor vehicle, has flux-conducting element extending over range of relative axial positions of permanent magnet
A magnetic signaling element (18) is arranged on one component, while a magnetic flux sensitive sensor (20) is arranged on another component. The sensor is provided with a fixed, flux-conducting element (22) which extends at least over the range of axial relative positions of the signaling element with respect to the sensor. The signal element is a permanent magnet, such as an annular magnet. The sensor is a Hall sensor. The flux-conducting element comprises sheet metal such as dynamo sheet.
