An electromechanical actuator (30) includes a ground arm (46), an output arm (48) rotatable about an axis of rotation (16) relative to the ground arm and a position sensing arrangement to determine an angular position of the output arm (48) relative to the ground arm (46). The position sensing arrangement includes a position sensor fixed at the ground arm. The position sensor is configured to sense magnetic reluctance. A sensed portion (64) is located at the output arm (48) proximate to the position sensor. The sensed portion (64) includes a geometric variation (78, 82) in an output arm surface (62) configured to vary a magnetic reluctance sensed at the position sensor as a function of angular position of the output arm (48) relative to the ground arm (46).
