Magnetic field at sensor: Tool to measure the valid air-gap (distances from magnet surface to sensor) given a certain magnet size and remanence (diametrical magnetization). Worst case angle error due to assembly tolerances: Tool to measure the worst case angle error caused by tilts and eccentricites of magnet and sensor elements against the axis of rotation. The worst case angle error is taken at the worst rotational position for the maximum assembly tolerances combination.
Simulation results based on worst case scenario.
NOTE: Tool describes purely the error contribution due to assembly tolerances. Additional tolerances based on the ICs temperature and life time drift are not considered!Please refer to datasheet, www.infineon.com/sensors
