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 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
In Stock
Five AET-Series models are in stock
