  • Patent number: 9297935
    Abstract: Devices and methods for providing sensor indication and enhancing sensor indication are disclosed. In one embodiment, a sensor indication is provided by sensing an operational status at a sensor circuit, generating a signal at the sensor circuit based on the sensed operational status, utilizing the signal to activate a light source, transmitting light into a first indicator layer with the light source, wherein the first indicator layer includes a fluorophore embedded within a substrate, and wherein the one or more fluorophores modify at least one characteristic of the transmitted light from the light source, and emitting the modified transmitted light from an end wall of the first indicator layer.

  • Patent number: 9157772
    Abstract: A variety of sensing assembly components, and methods of assembling, mounting, and orientating such assemblies and/or components, are disclosed. In one example embodiment, a sensing assembly includes a main body including at least a housing portion, and a mounting portion protruding outward from the main body. The mounting portion includes an outer connector section including at least one electrical connector, and an intermediate section that includes an outer surface that either has substantially a shape of a polygon or is at least partly threaded, where the intermediate section is positioned in between the main body and the outer connector section. Additionally, the intermediate section has an outer diameter, the outer connector section has an outer diameter, and the intermediate section outer diameter is greater than the outer connection section outer diameter. In other example embodiments, retaining structures on portions of a sensing assembly, or bracket assembly components, are provided.

  • Patent number: 8455831
    Abstract: Disclosed herein is a sensing assembly. The assembly includes a sensing assembly housing for enclosing an interior. The assembly further includes a plurality of sensing assembly components which are at least partially positioned, or at least partially contained, within the interior. And the assembly includes an indicator lens device which is integral with, or integrated with respect to the housing. In at least some embodiments, at least a portion of the housing coincides at least in part with a first axis and at least a portion of the indicator lens coincides with a second axis, such that the first axis and the second axis intersect to form an oblique viewing angle range and at least a portion of the indicator lens device is visible at least substantially throughout the oblique (e.g., obtuse) viewing angle range.

  • Publication number: 20110101967
    Abstract: An industrial control sensor is provided. The sensor includes a sensor circuit to detect changes in an electromagnetic field induced from an object or material passing in proximity of the electromagnetic field. This includes a housing that employs the sensor circuit as part of an inductive proximity sensor. A sensor face is attached to the housing, where the sensor face receives the changes in the electromagnetic field and transmits the changes to the sensor circuit, and where the sensor face has a higher electrical resistivity or a lower temperature coefficient of resistivity than stainless steel.
