Abstract (en)
[origin: EP0093859A2] 1. Piston whose position is to be sensed in a contactless manner, comprising an annular permanent magnet (11) which is arranged on both sides between discs (12, 13) which, together with the permanent magnet (11), are encased by sealing material (18) which also forms at least one sealing lip (20, 21) opposite the cylinder wall, characterized in that the permanent magnet (11) sits on a sleeve (10) which has a greater axial extent than the former, that there are intermediate spaces between the permanent magnet (11) and the discs (12, 13), designed as profile discs, with the exception of an area at the sleeve (10), that these intermediate spaces are filled by the sealing material (18) and that the inner side of the sleeve and also the discs, on all their outer sides, are encased by the sealing material (18).
