<p>Position sensor (10) for determining a linear position in a sensing direction, e.g. for application in a vacuum actuator. The position sensor (10) has a first sensor part and a second sensor part moveable with respect to each other. The first sensor part comprises an annular magnet (2) and a magnetic field sensor (3) positioned at a first distance (1 1 ) from the annular magnet on the magnet axis (1a). The second sensor part comprises a flux shaper (1) moveable through the annular magnet (2) along the sensing direction between a first and a second position, in the first position the flux shaper being substantially at the first distance (1 1 ) from the magnetic field sensor (3). The flux shaper is arranged to influence the magnetic field in a space between the annular magnet (2) and the magnetic field sensor (3).</p>
