NVE SM324-10E

NVE SM324-10E

The SM324-10E smart magnetometer from NVE is designed to provide ultra-precise magnetic field measurements, while detecting magnets even over 50mm away. It utilises Tunneling Magnetoresonance (TMR) technology, which is superior compared to the traditional Hall effect devices in terms of in-plane sensitivity, precision (±0.3% accuracy), speed (300 samples per second) and noise levels. The I2C interface works as data as well as programming interface; the progrrammable values include magnetic thresholds, sensor offset, temperature values, user defined memory and other values. The digital signal also allows for application-specific calibration; the calibration coefficient are stored in internal non-volatile memory. The SM124-10E is capable of withstanding harsh environments, including those in automotive applications, due to their robust ESD protection, and is available in ultraminiature TDFN6 package (2.5x2.5mm footprint).
