Abstract
An actuator and sensor assembly comprising respective sensor and actuator housings defining an interior chamber. Clips on the sensor housing engage the actuator housing for coupling the sensor and actuator housings together. The sensor housing includes a wall defining a pocket. A connector with a sensor couples to the sensor housing in a relationship wherein the sensor extends into the sensor housing pocket. A movable piston is located in the interior chamber and a tube thereon defines a receptacle for a magnet located adjacent the pocket. The piston is seated on a flexible diaphragm. An actuator shaft includes one end coupled to the piston and an opposite end coupled to a movable object. A plurality of pins in the actuator housing mount the assembly to a support bracket. The sensor senses changes in the magnetic field in response to changes in the position of the magnet relative to the sensor.
