In an embodiment of a rotational sensor, a multi-pole magnet assembly comprises multiple magnets configured to rotate about a rotational axis of the rotational sensor, where the multi-pole magnet assembly is in a first plane perpendicular to the rotational axis. The magnetic sensor is arranged in a second plane also perpendicular to the rotational axis and in proximity to the multi-pole magnet assembly. Each magnet of the multiple magnets has poles aligned parallel to the rotational axis and perpendicular to the first plane of the magnetic sensor. In another embodiment, the magnetic sensor is arranged at a first radius away from the rotational axis, whereas the multiple magnets of the magnet assembly are arranged at a second radius, not equal to the first radius, away from the rotational axis. In yet another embodiment, a rotational sensor comprises a housing and rotatable shaft upon which the magnet assembly is mounted. |
