NVE Launches AET Line of High-Resolution
TMR Rotational / Linear Sensors
EDEN PRAIRIE, Minn.September 14, 2020NVE has launched the new AET-Series
of TMR off-axis rotational / linear sensors, the worlds only tunneling magnetoresistance
(TMR) encoder sensors.
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.
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.
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
Excellent linearity and low distortion
350 kilohertz operating frequency
150 degrees Celsius operating temperature
AET-Series applications include:
Linear motion sensors
Motion, speed, and position sensing
Five AET-Series models are in stock for immediate delivery:
