NEW! World’s Most Sensitive
Ultraminiature Rotation Sensor
 
NVE’s new Tunneling Magnetoresistance (TMR) dual-axis sensor, the ALT521-10E, is the world’s most sensitive device of its type.
ALT521 Transfer Function
Ultrahigh Sensitivity
The new sensor has two independent sensing axes, each with a high-sensitivity 140 mV/V/mT output. The sensor can detect rotating magnetic fields as small as 0.1 µT and can detect orientation in Earth’s 50 µT magnetic field without external amplifiers.

Ultralow Power Consumption
ALT521-10E are built as Wheatstone bridges with a typical resistance of two megohms, meaning they draw less than one microamp from a single-cell battery. They are ideal for high-speed, continuous-duty operation from low-voltage batteries.

Ultraminiature
At just 2.5 x 2.5 x 0.8 millimeters, the ALT521-10E enables further miniaturization of wearable, battery-powered instruments.
 
Best-in-Class Specifications
  • High sensitivity (140 mV/V/mT)
  • ±0.5 mT linear range
  • Highly linear output (typ. 2% of full scale)
  • Low temperature coefficient of output (0.1%/°C)
  • 100 kHz frequency bandwidth
  • 2 megohm typ. device resistance for low power
  • Operation to near-zero supply voltage
  • Up to 125 °C operating temperature
  • 2.5 x 2.5 mm DFN6 package

Typical Applications
  • Flowmeters
  • Earth magnetic field detection
  • Wearable and battery powered devices
  • Proximity sensing
  • RPM speed measurement
  • Ferromagnetic material detection
  • Nondestructive testing
  • Freepitch rotary encoders
  • Freepitch linear encoders
  • Joysticks
  • Battery-free servo encoders
