Assignee:

Allegro Microsystems, Inc. - Worcester MA

International Classification:

B29C 4514

US Classification:

264255, 2642711, 26427215, 26427219

Abstract:

A magnet structure including a magnet and an integral magnetically permeable concentrator and methods for making the same are provided. The concentrator is comprised of a plastic loaded with one or more magnetically permeable materials to a percentage suitable for providing desired magnetic field characteristics. The magnetic element may be comprised of a conventional magnetic material or a plastic loaded with one or more magnetic materials. An insert molding technique is described in which either the concentrator or magnetic element is prefabricated and inserted into a mold which is subsequently filled with a loaded plastic to provide the other component of the magnet structure. In an alternate fabrication technique, both the concentrator and magnet are sequentially formed by injection molding in the same mold. Also described is a magnet structure including a ring magnet having a central aperture in which a steel rod is disposed.

Assignee:

Allegro Microsystems, Inc. - Worcester MA

International Classification:

G01R 1520

US Classification:

324117H, 324126

Abstract:

An integrated current sensor includes a magnetic field transducer such as a Hall effect sensor, a magnetic core, and an electrical conductor. The conductor includes features for receiving portions of the Hall effect sensor and the core and the elements are dimensioned such that little or no relative movement among the elements is possible.

Assignee:

Allegro Microsystems, Inc. - Worcester MA

International Classification:

H01L 43/00

US Classification:

257421, 257108, 257414, 257422, 257423, 257425, 257427

Abstract:

An integrated sensor has a magnetic field sensing element and first and second relatively high magnetically permeable members forming a gap, wherein the magnetic field element is disposed within the gap. The magnetically permeable members provide an increase in the flux experienced by the magnetic field sensing element in response to a magnetic field. The integrated sensor can be used as a current sensor, a proximity detector, or a magnetic field sensor.

International Classification:

G01B 714

US Classification:

3242072

Abstract:

A magnet structure including a magnet and an integral magnetically permeable concentrator and methods for making the same are provided. In one embodiment, the concentrator has a substantially planar base and a post extending normal to the base and the magnetic element is a ring magnet having a central aperture through which the concentrator post extends. The concentrator is comprised of a plastic loaded with one or more magnetically permeable materials to a percentage suitable for providing desired magnetic field characteristics. The magnetic element may be comprised of a conventional magnetic material or a plastic loaded with one or more magnetic materials. An insert molding technique is described in which either the concentrator or magnetic element is prefabricated and inserted into a mold which is subsequently filled with a loaded plastic to provide the other component of the magnet structure. In an alternate fabrication technique, both the concentrator and magnet are sequentially formed by injection molding in the same mold. Also described is a magnet structure including a ring magnet having a central aperture in which a steel rod is disposed.
