Abstract:
1. An actuator assembly, comprising: a positioning element carried by a housing, the positioning element having a first end and a second end opposing the first end, the first end of the positioning element being constructed and arranged to be coupled to a control element; a rotational member defining a helix extending between a first end of the rotational member and a second end of the rotational member, the first end opposing the second end, the rotational member having a first portion carried by a bearing element disposed at the second end of the positioning element and a second portion rotatably coupled to the housing; and a sensor assembly having a magnet portion disposed at the second end of the rotational member and a sensor portion carried by the housing, the sensor portion disposed in electro-magnetic communication with the magnet portion, the bearing element configured to rotate the rotational member and the magnet portion relative to the sensor portion when the positioning element linearly translates between a first position and a second position.
