NVE Introduces Ultrahigh Field TMR
Analog Magnetic Sensor
EDEN PRAIRIE, Minn.June 22, 2020Based on NVE’s proprietary Tunneling
Magnetoresistive (TMR) technology, the new AKT001-14E is an analog magnetometer
sensor providing precise sensing over an unmatched field range up to a remarkable
1.5 tesla. The output does not depend on field direction or polarity, which is
a unique property for a magnetic sensor, and allows unprecedented flexibility
for applications such as brushless DC motors, motor commutator sensors, and noncontact
AKT001 specifications include:
• 0.05 to 0.8 tesla linear range
• 1.5 tesla saturation
• 1 megohm bridge for low power
• Ratiometric Wheatstone bridge outputs
• Any supply voltage up to 5.5 volts
• Ultraminiature 1.1 by 1.1 millimeter package
The sensor is configured as a Wheatstone bridge. The differential output is ratiometric
with supply voltage and is temperature compensated.
Sensitivity in Any Direction
The sensor response is both omnipolar and omnidirectional. The sensor output is
unchanged by the field polarity or direction. Only the magnetic field magnitude
increases the sensor output.
TMR technology generates very large signals, typically 25 millivolts per volt
at 0.5 tesla, for high signal-to-noise measurements and high-reliability applications.
AKT001 sensors are not adversely affected by magnetic fields larger than the saturation
Parts are in stock for immediate delivery. AKT001-14E sensors are priced at $5.45 each
in 1000-piece quantities.
