NVE Launches AET Line of High-Resolution
TMR Rotational / Linear Sensors
EDEN PRAIRIE, Minn.—September 14, 2020—NVE has launched the new AET-Series of TMR off-axis rotational / linear sensors, the world’s only tunneling magnetoresistance (TMR) encoder sensors.  Versatile The sensors can be used with multipole ring magnets as rotary encoders or with magnetic scale tapes as linear motion sensors. High sensitivity allows for wide airgaps and accommodates mechanical tolerances. Simple Interfaces AETxxx half-bridge versions offer simplicity and miniaturization. AETxxxF full-bridge versions provide twice the output signal and maximize noise immunity. Sine and cosine outputs provide direction information. Typical output amplitude is 200 millivolts peak-to-peak per volt for half-bridge versions and 400 millivolts peak-to-peak per volt for full-bridge versions. The large output signals allow direct interface to common microcontrollers with no amplification. Ridiculous Precision Standard AET-Series sensors are designed for pole pitches from 0.5 to 5 mm. Custom spacings are also available. Typical resolution is one one-thousandth of the pole pitch, or or as little as 0.5 microns for linear motion sensing and 0.02 degrees for rotation sensing with a 16-pole ring magnet. Key AET-Series sensor features include: • Large analog signals (to 400 millivolts peak-to-peak per volt) • Excellent linearity and low distortion • 350 kilohertz operating frequency • 150 degrees Celsius operating temperature AET-Series applications include: • Rotary encoders • Linear motion sensors • Motion, speed, and position sensing • Closed-loop servos • Automotive sensors Available Now Five AET-Series models are in stock for immediate delivery:
Demonstration and Evaluation Kits The AG965-07E Demonstration Kit showcases micron precision with an AET500-02E sensor. The kit includes: • A three by five-inch (76 by 127 millimeters) printed-circuit board • An AET500-02E five-millimeter pole-pitch sensor • On-board amplifier and microcontroller • A four-digit position display • Five-millimeter pole-pitch magnetic tape • 3-D printed fixturing • LEDs to indicate pole detection • Powered by three AAA batteries (included) The AG970-07E Evaluation Kit helps test AET-Series sensors with magnetic linear scale tape. The kit includes: • All five AET-Series parts (unsoldered in tubes) • A three by four-inch (76 by 101 millimeters) PCB with test points and screw terminals • Detachable fixturing for magnetic linear scale tape (tape sold separately) Available Now AET-Series sensor prices start at $1.78 each in 1000-piece quantities. The AG965-07E Demonstration Kit price is $195 in single-piece quantities and the AG970-07E Evaluation Kit is priced at $65.
