<p>The device has a housing (22) made up of a non-magnetic material. A scanning carriage (10) scans a measuring graduation of a scale (20). The carriage is rigidly coupled in a measuring direction, and is flexibly coupled to a driver (13) in a transverse manner. The driver is fixed to an object (1) e.g. carriage. The carriage is longitudinally guided to guiding surfaces (201, 202), and is pressed on the surfaces that run perpendicular to each other. Pressing forces (Fy) are produced by magnetic force between a permanent magnet (161) of the carriage and a steel band (261) provided in the housing.</p> |
