NEW! TMR Rotational / Linear Sensors
AET-Series Encoder Sensor
NVE has launched the new AET-Series of TMR off-axis rotational / linear sensors, the world’s only tunneling magnetoresistance (TMR) encoder sensors.
The sensors can be used with multipole ring magnets as rotary encoders or with magnetic linear scale tape 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. The output amplitude is 200 mVpp/V typ. for half-bridge versions and 400 mVpp/V 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 mVpp/V)
  • Excellent linearity and low distortion
  • 350 kHz operating frequency
  • 150°C operating temperature
AET-Series applications include:
  • Rotary encoders
  • Linear motion sensors
  • Motion, speed, and position sensing
  • Closed-loop servos
  • Automotive sensors
