Abstract
A sealed sensor apparatus for a light fixture includes a housing. The housing has a base portion configured to house circuitry of the sensor apparatus. The housing include an integral cylindrical extension projecting from the base portion. The cylindrical extension has an interior surface defining an interior cavity. The cylindrical extension has an exterior surface radially spaced from the interior surface. A gasket may be received about the exterior surface of the cylindrical extension. A lens may be sealingly mounted to the cylindrical extension.
Claims10
A sealed sensor apparatus comprising:
- a housing including
- a base portion configured to house circuitry of the sensor apparatus, and
- an integral cylindrical extension projecting from the base portion, the cylindrical extension including an interior surface defining an interior cavity and an exterior surface radially spaced from the interior surface;
- a gasket received around the exterior surface of the cylindrical extension, wherein the gasket includes a radially inward projection adjacent a distal end of the cylindrical extension such that the gasket contacts both the exterior surface and the interior surface of the cylindrical extension;
- a lens sealingly mounted to the cylindrical extension;
- wherein the gasket further includes an outer gasket surface including a mounting groove defined therein;
- and wherein the gasket further comprises an outwardly projecting sealing rib spaced from an outwardly projecting gasket shoulder, the sealing rib and gasket shoulder defining the mounting groove therebetween.
A sealed sensor apparatus comprising:
- a housing including
- a base portion configured to house circuitry of the sensor apparatus, and
- an integral cylindrical wall projecting from the base portion, the cylindrical wall including a central axis and a cylinder length defined along the central axis;
- and
- a gasket disposed on the cylindrical wall and coextensive with a majority of the cylinder length, wherein the gasket further includes:
- an outwardly projecting gasket shoulder, and
- an outwardly projecting sealing rib spaced from the outwardly projecting gasket shoulder, the sealing rib and gasket shoulder defining a mounting groove therebetween.
A sealed sensor apparatus comprising:
- a mounting plate;
- a mounting hole defined in the mounting plate by a hole perimeter surface of the mounting plate, the hole perimeter surface parallel to an axis of the mounting hole;
- a housing including a base portion and an integral cylindrical portion extending therefrom, the cylindrical portion inserted in the mounting hole;
- and
- a gasket disposed between the cylindrical portion and the hole perimeter surface, wherein the gasket includes:
- an outwardly projecting gasket shoulder, and
- an outwardly projecting sealing rib spaced from the outwardly projecting gasket shoulder, the outwardly projecting sealing rib and outwardly projecting gasket shoulder capturing the mounting plate therebetween.
