NVEs new Tunneling
Magnetoresistance (TMR) dual-axis sensor, the ALT521-10E,
is the worlds most sensitive device of its type.
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 Earths 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.
