Rotary Sensor Module with Axial Switch

摘要

Sensor assembly comprising a first rotary sensor part with a plurality of individual electrically conducting sensor areas arranged in a pattern, a second rotary sensor part arranged rotationally relative to the first portion, the second part comprising a plurality of contact structures adapted to be in contact with conducting sensor areas on the first sensor rotary part. The contact structures are configured to engage and connect different sensor areas as the first and second part of the rotary sensor rotate relative to each, the created connections being indicative of a rotational position between the first and second portions. One of the contact structures is an actuatable contact structure being axially moveable relative to the first portion and having a connected position in which the actuatable contact structure is in contact with a sensor area and a disconnected position in which the actuatable contact structure is not in contact with a sensor area.

1. A rotary sensor assembly defining an axis of rotation, comprising:
a first portion comprising a first rotary sensor part, the first rotary sensor part comprising a surface with a plurality of individual electrically conducting sensor areas arranged in a pattern, a second portion comprising a second rotary sensor part arranged rotationally relative to the first portion, the second rotary sensor part comprising a plurality of contact structures adapted to be in contact with conducting sensor areas on the first sensor rotary part,
wherein at least a portion of the contact structures are configured to engage and connect different sensor areas as the first and second part of the rotary sensor rotate relative to each, the created connections being indicative of a rotational position between the first and second portions,wherein at least one of the contact structures is an actuatable contact structure being axially moveable relative to the first portion and having a connected position in which the actuatable contact structure is in contact with a sensor area and a dis-connected position in which the actuatable contact structure is not in contact with a sensor area, actuator structure means for axially moving the at least one actuatable contact structure between the connected and the dis-connected position.
