Devices (1) comprising sensor arrangements (10) with field detectors (12) for detecting components (18) of magnetic fields in planes of the field detectors (12) and with movable objects (13) for, in response to tilting movements, changing at least parts of the components (18) of the magnetic fields in the plane; of the field detectors (12) are made less sensitive to in-plane stray fields by providing the fold detectors (12) with saturated field-dependent elements (31). The movable object (13) 1 nay comprise a movable field generator for generating the magnetic field, or the movable of object (13) and the field generator (11) may be different objects. The magnetic field is such that the field-dependent element (31) is saturated. The field generator (11) is smaller than the field detector (12), and the movable object (13) is larger than the field detector (12), to reduce alignment problems. The movable object (13) has a pivoting point close to the field detector (12). |
