Honeywell adds the SS39ET integrated circuits (IC) series to its linear Hall-effect magnetic position sensor product line. The SS39ET Series’ SOT-23 features a subminiature footprint that requires less space on a PC board, making it suitable for compact designs and allowing more flexibility. The series monitors magnetic fields from a permanent magnet or an electromagnet. Packages can be supplied on tape for automated assembly. Devices respond to both north and south poles and can be powered with as little as 2.7 V. Other features include a -40 to +100°C (-40 to +212°F) temperature range and thin film resistors to improve accuracy and output. Potential applications include magnetic field and basic current sensing, heavy-duty equipment pump control, linear or angular displacement sensing, and speed adjustment.
