Rotary Sensor Assembly with Space Efficient Design
First Claim
1. A sensor assembly comprising:
- a first rotary sensor part comprising a surface having;
a circumferentially arranged reference track,a plurality of individual electrically conducting code segments arranged in a pattern, each code segment being arranged in the reference track but electrically isolated therefrom, thereby forming a plurality of electrically conducting reference segments between the code segments,a second rotary sensor part arranged rotationally relative to the first part, comprising;
a plurality of contact structures, each contact structure being arranged to be in contact with either a code segment or a reference segment depending on the rotational position between the first and second rotary sensor part,wherein;
the contact structures are configured to engage and connect to different sensor segments as the first and second rotary sensor part rotate relative to each, the created connections being indicative of a rotational position between the first and second rotary sensor part, andfor a given rotational position, at least one contact structure engages a code segment and at least one contact structure engages a reference segment.

Abstract
A sensor assembly comprising a first rotary sensor part having a plurality of individual electrically conducting code segments arranged in a circumferential pattern, and a plurality of electrically conducting reference segments between the code segments, and a second rotary sensor part arranged rotationally relative to the first part a plurality of contact structures, each contact structure being arranged to be in contact with either a code segment or a reference segment depending on the rotational position between the first and second rotary sensor part. The contact structures are configured to engage and connect to different sensor segments as the first and second rotary sensor part rotate relative to each, the created connections being indicative of a rotational position between the first and second rotary sensor part. For a given rotational position, at least one contact structure engages a code segment and at least one contact structure engages a reference segment.
