NVE Corporation has introduced the AAT009-10E Ultralow-Power Tunneling Magnetoresistance (TMR) Angle Sensor, a high-output magnetic sensor for angle measurements based on rotating magnetic fields.
The AAT009 has six megohm device resistance for ridiculously low power consumption, and can run years on a single button cell or on scant harvested power. Harvested power can be intermittent, and AAT-Series sensors detect and maintain absolute position information, and immediately power up in the correct position after power is restored.
Key AAT009 features include:
- Six megohm typical device resistance for ultralow power consumption
- 0.5 degrees maximum angular measurement error with fixed magnetic bias
- 200 mV/V peak-to-peak output signals
- Wide magnet airgap tolerance
- Sine and cosine outputs for direction detection
- Ultraminiature 2.5 mm x 2.5 mm x 0.8 mm TDFN6
Because they are resistive devices with no active components, AAT-Series sensors have no minimum voltage and can be powered from single cells.
