1. A linear position sensor comprising:
- a housing;
a magnet carrier located and movable linearly in the housing, magnet carrier including a base;
a magnet on the magnet carrier;
a shaft extending in the housing; and
a plate located in the housing between the shaft and the magnet carrier, the shaft secured to the plate and the plate secured to the base of the magnet carrier, the plate including at least one finger coupled to the base of the magnet carrier for preventing the rotation of the magnet carrier relative to the plate.

Abstract
A sensor used to sense the position of an attached movable object. The sensor can be mounted to a pneumatic actuator. The sensor includes a housing that has a pair of cavities or pockets separated by a wall. A magnet carrier is positioned within one of the cavities and a magnet is coupled to the magnet carrier. The magnet carrier is coupled to the moveable object. A magnetic sensor is positioned in the other of the cavities. The magnetic sensor generates an electrical signal that is indicative of a position of the movable object.
