NVE
Announces the World’s Most Sensitive Off-Axis Rotation Sensor
EDEN PRAIRIE, Minn.—August 18, 2025—NVE Corporation today announced the new ADT501-10E, an ultrasensitive, ultralow power, digital-output rotation sensor providing accurate, absolute rotational quadrant information from a rotating magnet. The new part works with two-pole and multipole magnets, and works just as well off-axis as it does on-axis.  Revolutionary Technology Tunneling magnetoresistance (TMR) technology allows the sensor to work with as little as 0.4 millitesla magnetic field, allowing small magnets and extremely wide airgaps. Key features include: • Precision digital quadrant outputs • Works with as little as 0.4 millitesla magnetic field • Extremely low power (4 microamps maximum at 2.4 volts) • Off-axis sensing capability • Wide airgap tolerance • 2.4 to 5.5-volt supply range • -40 to 125 Celsius operating range • 2.5 by 2.5 by 0.8 millimeter DFN6 package Simple Interface The heart of the unique sensor is an array of four Tunneling Magnetoresistance (TMR) elements, one for each quadrant. Two binary outputs correspond to the sine and cosine of the rotation. Design Support An available breakout board has a pre-soldered sensor, a standard header, and a card-edge connector for easy connections. The breakout board can be used separately or with NVE’s Arduino Shield demonstration and development board. The Shield has sixty LEDs to indicate angle and direction of rotation, and is compatible with a number of NVE TMR angle and rotation sensors. A Full Product Line The ADT501-10E is the fifth model in NVE’s unique line of rotation sensor models. Sensors are available with various operating field ranges and output configurations. Available Now The ADT501-10E and breakout boards are in stock for immediate delivery. More Information Visit NVE’s website (www.nve.com) for detailed specifications and pricing.
