Abstract: A gas sensor assembly including a substrate located in a housing. The substrate includes a high temperature gas sensor end and a lower temperature electronics end. A heat transfer, sealing, and support plug is mounted in the housing to the substrate. The plug seals the sensor end from the electronics end and transfers the heat generated at the high temperature sensor end successively through the substrate, the thermally conductive plug, the housing, and into the outside air. In one embodiment, the housing includes a collar which surrounds a portion of the substrate and is coupled to and supported on one end of the plug and a jacket which surrounds the electronics end of the substrate and includes a neck coupled to and supported on an opposite end of the plug.

Abstract: A position sensor is nested into a cup-shaped portion of a molded pedal. The pedal directly drives the position sensor rotor, but the sensor is fully self contained and environmentally sealed. By nesting the sensor within the pedal, assembly is simplified and alignment of components is easily ensured. Additionally, the pedal still retains sufficient width to be designed to have adequate strength. The pedal structure may then be assembled easily and with few pieces, while still ensuring the proper functioning and internal alignment of the sensor.
