March 6, 2012 – Honeywell releases SS39ET Linear Hall Effect Sensor IC. The SS39ET Series 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
- Current sensing in appliances
- Speed adjustment trigger in tools and appliances
- Magnetic code reading in safes, security, and building access control systems.
“With the launch of the new SS39ET Series, customers can choose the package style and size to meet their application needs,” said Josh Edberg, senior global product marketing manager for Honeywell Sensing and Control. “Customers will appreciate the SS39ET Series’ SOT-23 subminiature footprint that takes up less space on the PC board, allowing more design flexibility and cost savings in their application.”
