摘要： 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.

摘要： A current sensor is provided with a flux concentrator which is made of two or more annular laminae. The laminae, or lamina plate, each are provided with a gap formed in its circumferential length. Each lamina has a gap which is defined by two opposing faces. The laminae are stacked with their planar surfaces in contact and in such a way so as to define a central opening. The gaps of the laminae are arranged proximate each other. One lamina is rotated relative to another to change the width of the effective gap by misalign the faces of the one gap relative to another. The lamina is rotated during the manufacture of the current sensor while an output voltage signal is measured as a function of a current passing through an opening of the flux concentrator. The degree of rotation of the lamina is determined as a function of the output signal to achieve a preselected current/voltage relationship. By achieving a consistent relationship between current sensors made in accordance with the present invention, interchangeability from one current sensor to another can be achieved in a low costs current sensor.
