Abstract
A Hall-effect sensor package for sensing electrical current in an electrical conductor, is provided which includes a ferromagnetic core having an air gap, the core allowing for the electrical conductor to pass therethrough. The sensor package also includes a Hall-effect generator, at least a portion of the Hall-effect generator being located within the air gap, and a lead frame coupled to the Hall-effect generator. An insulative material is used to encapsulate the Hall-effect generator and at least a portion of the core and the lead frame. The insulative material facilitates binding of the Hall-effect generator, the lead frame and the core. The insulative material also facilitates protecting the Hall-effect generator from contaminants.
