A range of MagnetoResistive FixPitch position sensors from Sensitec, available in a range of different pitches. Each position sensor incorporates two Wheatstone bridges on chip.
The sensor outputs are proportional to sine and cosine of the coordinates measured. Each sensor is matched to a particular pole length (equivalent to half the magnetic period). PerfectWave technology is incorporated to ensure that the higher harmonics are removed and precision is maintained by using multiple sensors.

Contactless angle and position measurement
Large air gap
Excellent accuracy
Minimized offset voltage
Negligible hysteresis

Suitable applications for these position sensors include motor integrated encoders and motor feedback systems.
