| 摘要 |
The invention relates to a sensor (2) for emitting an electrical signal based on a travel to be detected, comprising a casing (4), which forms the boundary between an interior space (10) and an exterior space (12), a pick-up (6) penetrating the casing (4) from the exterior space (12) into the interior space (10) and having a travel sensor element (26) in the exterior space (12) and a field sensor element (36) in the interior space (10), wherein the travel sensor element (26) is configured to rotate the field sensor element (36) against the casing (4) on the basis of the travel to be detected, an analyser circuit (48) to detect a physical field output by the field sensor element (36) and a moisture protection element (37, 40, 42) to protect a gap between the casing (4) and the pick-up (6) against penetrating moisture (38). |
