A magnetic sensor is provided in which a flexible substrate is used to support a magnetically sensitive component and other electronic components relative to the position of a permanent magnet. A thermoset material is used as an encapsulant to form a solid magnetic sensor in which the magnetically sensitive component, the permanent magnet and a portion of the flexible substrate are encapsulated within the thermoset material after it solidifies. A portion of the flexible substrate extends from an end of the solidified encapsulant to permit electrical connection to other components and devices.

Magnetic sensor with encapsulated magnetically sensitive component and

A magnetic sensor is provided with a housing in which a carrier is inserted. The carrier is particularly shaped to retain a permanent magnet in a particular position relative to a plurality of electrical conductors and a substrate on which a magnetically sensitive component is attached. The carrier and its associated components is inserted into a housing which can be deformed to permanently retain the carrier within a cavity of the housing. All of the components of the sensor are designed to be easily assembly along a common axis to facilitate automatic assembly and manufacture of the sensor. The magnetically sensitive component can be a Hall effect element that is associated with other electrical components which are also attached to a substrate that is disposed proximate a front end of the carrier.

A mass air flow sensor having a probe body defining a first arcuate passageway connecting a flow entrance opening aligned with an axis and a flow exit opening offset from the axis so that contaminants suspended in fluid flowing through the first passageway are driven by centrifugal force toward the outer wall thereof. A second passageway is connected to a sampling port in the inner wall of the first passageway, and has located therein a flow detector of the type having a thin film heater and at least one thin film heat sensor spaced from the heater along the direction of flow.
