The detector (1) has a housing (10), and track wheels (2, 3) that are arranged in the housing and fastened to track arms (11, 12). A linear drive (4) is connected with linear guides (14, 15), where lifting and lowering of the track wheels takes places along the linear guides. The linear guides comprise lateral limitations, and spring elements (8, 9) are connected to the track arms. A sensor is arranged in the housing, where the track wheels are guided on the sensor. |
