1. An apparatus comprising:
a first physical component; a second physical component; and a sensor arrangement, wherein: the first physical component and the second physical component are configured for moving relative to one another in operational use of the apparatus, the sensor arrangement is configured for sensing a relative kinematic state of the first physical component and the second physical component, the sensor arrangement comprises a magnet and a sensor, the sensor is operative to sense a property of a magnetic field of the magnet at a location of the sensor, the sensor is mounted stationary with respect to the first physical component, the sensor arrangement comprises a target object that is mounted stationary with respect to the second physical component, the target object is configured for affecting an attribute of the property in dependence on the relative kinematic state, the target object comprises a plurality of interlocking segments, the plurality of interlocking segments comprises a first segment and a second segment, the first segment has a first interface and the second segment has a second interface, the first interface and the second interface are configured for interlocking the first segment and the second segment, a first shape of the first interface and a second shape of the second interface are formed spatially complementarily, the first shape of the first interface extends in a first direction of the relative movement of the first physical component and the second physical component and has a first profile that varies in a second direction that is substantially perpendicular to the first direction, and the second shape of the second interface extends in the first direction and has a second profile that varies in the second direction. |
