Angle and length measurement Durable and highly accurate

FreePitch sensors have been optimized to the extent that they can be used independent of the pole length of the measurement scale. This has the benefit of them being particularly compact and coming very close to a point sensor. They are the ideal choice if a particularly cost-effective solution is needed for the measurement task. In order to keep the dimensions as small as possible, the Wheatstone bridges are nested within each other. In order to generate the sine/cosine signals, both bridges are positioned at an angle of 45° to each other. FreePitch sensors can be used with pole rings or linear scales with almost any pole length, as well as with dipole magnets.

FixPitch sensors are adjusted to the pole lengths of the measurement scale, i.e. MR strips are geometrically coordinated to a specific pole length. The sine and cosine signals are generated by distributing the Wheatstone bridge resistances along the single pole. This geometric arrangement contributes to the suppression of the harmonics and a reduction in the sensitivity to stray fields. This optimizes the linearity of the sensor.
