1. An actuator and sensor assembly comprising:
- a sensor housing including an interior wall defining a pocket accessible through an opening in the sensor housing;
a sensor substrate located in the pocket through the opening in the sensor housing, the sensor substrate having a sensor and defining a plurality of conductive through-holes;
a hose retention assembly including a nozzle extending from the sensor housing and a sleeve surrounding and spaced from the nozzle;
a hose coupled to and surrounding the nozzle and the sleeve surrounding and abutting against the hose for retaining the hose on the nozzle;
a connector assembly associated with the sensor housing and located opposite and generally normal to the pocket and the substrate and including a plurality of compliant terminal pins extending into the pocket and the plurality of through-holes in the sensor substrate respectively;
an actuator housing coupled to the sensor housing and together defining an interior cavity and an actuator housing aperture in communication with the interior cavity, the actuator housing including an interior collar;
a gimbal including a head located in the collar and a flexible neck extending through the actuator housing aperture in the actuator housing and terminating in a shoulder that retains the gimbal in the collar of the actuator housing;
an O-ring surrounding the head of the gimbal and in sealing abutting relationship with the interior surface of the collar of the actuator housing;
a magnet carrier located and movable in the interior cavity and including a magnet adapted to generate a magnetic field and the sensor adapted to sense a change in the magnetic field in response to the movement of the carrier and the magnet in the interior cavity relative to the sensor; and
an actuator shaft including a first end extending through the aperture in the actuator housing and the gimbal and coupled to the magnet carrier.

Abstract
An actuator and sensor assembly with a housing defining a pocket and an access opening. A substrate with a sensor is located in the pocket through the access opening. A nozzle extends from the housing. A sleeve surrounds the nozzle and retains a hose on the nozzle. A connector assembly is located opposite and normal the pocket and the substrate. Compliant terminal pins extend generally normally from the connector assembly into the pocket and through-holes in the substrate. An actuator shaft gimbal includes a head located in a housing collar and a flexible neck extends through a housing aperture. A shoulder on the neck of the gimbal locks the gimbal in the collar.
