Honeywell is extending its linear Hall-effect sensor integrated circuits (IC) product line with the addition of the new SS39ET Series. The sensor ICs are designed to monitor magnetic fields from a permanent magnet or an electromagnet. All packages can be supplied on tape for automated, lower-cost assembly. These devices respond to both North and South poles, and can be powered with voltages as low as 2.7 V. A wide temperature range of -40 °C to 100 °C [-40 °F to 212 °F] allows use in many environments, and the thermally balanced, integrated circuit provides stable operation over the full temperature range. Thin film resistors improve accuracy and provide a stable output. The energy-efficient, low current consumption of 6 mA at 5 Vdc and the 2.7 VDC to 6.5 VDC supply voltage range allow circuit design flexibility. Potential industrial applications for the SS39ET Series include anti-tampering magnetic field sensing in smart remote utility meters; basic current sensing for motor load monitoring, detection; pump control in heavy-duty equipment and household appliances; simple linear or angular displacement sensing; handlebar/throttle position sensing in e-bikes and scooters; current sensing in appliances; speed adjustment trigger in tools and appliances; magnetic code reading in safes, security, and building access control systems. Potential medical applications for the SS39ET Series include position sensing in infusion pumps.
