FreePitch sensors Sensor design without polar adjustment.
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.
AMR sensors are based on the anisotropic MagnetoResistive effect and stand out because of their high accuracy and large tolerance regarding the working distance between the sensor and the measurement scale.
