Early in the study of electronics we are introduced to magnetism. The lines of force can be demonstrated by iron filings on a sheet of paper with a magnet underneath. In school science class, we made ...

Hall-effect switches and instrumentation-grade sensors have become more commonplace in industrial applications, with a wide range of Hall-effect devices now packaged for designers of products and ...

Sponsored by Texas Instruments: Offering alternatives to shunt resistors, Hall-effect devices have evolved to offer the accuracy and stability necessary for measuring current in demanding high-voltage ...

Developed for space and other harsh environments, a Hall-effect sensor from TT Electronics OPTEK Technology performs stable position sensing over a wide range of temperatures while operating over a ...

Texas Instruments has introduced the industry’s most sensitive in-plane Hall-effect switch for position sensing, providing ...

The ATS682LSH from Allegro MicroSystems is a Hall-effect sensing integrated circuit and magnet combination that is intended for true zero-speed sensing of ferrous targets in two-wire applications. The ...

Whether you're a motor designer/builder or buyer/user, understanding how the efficiency of brushless DC motors is improved with the use of Hall-effect sensors is important to your building and/or ...

Allegro Microsystems has introduced isolated differential current sensor ICs based on the Hall effect. Accuracy is typically +/-1% from 25 to 125°C, and +/-3% from -40 to +25°C. Both the ACS724KMA ...
