Versatile sensors are ideal for measuring current or proximity
NVE Corporation announced the new SM324-10E Smart Magnetometer. The new sensor combines a unique Tunneling Magnetoresistance (TMR) sensor element with sophisticated digital signal processing. The versatile product is ideal for measuring current or proximity.
Amazing Features
Unlike awkward, old-fashioned Hall-effect sensors, TMR is sensitive in-plane for optimal current sensing and easy mechanical interfaces. Key SM324-10E features include:
- Can detect magnets more than 50 mm away
- I2C and digital threshold outputs
- 24-bit output resolution
- In-plane sensitivity more usable than Hall effect sensors
- Programmable offset and gain compensation
- Internal temperature compensation
- 1.68 to 3.6 volt supply
- Ultraminiature 2.5 × 2.5 × 0.8 mm TDFN package

The kit includes:
- An evaluation board with:
- an SM324-10E sensor.
- a microcontroller connected to the sensor via I2C.
- a current-carrying trace under the sensor for evaluating as a current sensor.
- A powerful, intuitive graphical user interface.
- Simple software installation.
- Flexibility to power from USB or external power supply.
- Isolated USB interface for safety and low noise.
- USB cable to connect the Evaluation Board to a computer.
- A small ceramic magnet for evaluating as a proximity sensor.
SM324-10E Smart Magnetometers are priced at $1.94 each in 1000-piece quantities. The AG951-07E Smart Magnetometer Evaluation Kits are priced at $245.00 each. Sensors and kits are both in stock for immediate delivery.
