Linear Position Sensing with Magnetic Scale Tape

We demonstrate linear position sensing using magnetic scale tape and our new TMR magnetic encoder sensors. These sensors can precisely interpolate hundreds of points between magnetic poles for micron-level precision. The sensors have large signals and low impedance, so they can be connected directly to an Arduino or other microcontroller. The sensor provides sine and cosine outputs, with the magnetic pitch representing 360 degrees. We can read the sensor and calculate the position with a single line of code. The quadrature outputs also allow us to determine the direction of travel. AET-Series sensors have large output signals, excellent linearity, and low distortion. Versions are available for a range of pole pitches.
