TMR angle sensor boasts ±0.2° accuracy for 360° contactless sensing

June 13, 2017 // By Julien Happich
Delivered with a digital output, TDK's latest Tunnel Magneto Resistance (TMR) angle sensor offers a guaranteed accuracy of ±0.2° and at room temperature achieves the industry’s highest accuracy for angle error of only ±0.05°.

The TAD2141 sensor is capable of contactless sensing 360° within a temperature range of -40 to +150°C. Furthermore, the new TAD2141 sensor represents a remarkable level of miniaturization and weight-saving in comparison with conventional solutions using resolvers. Engineering samples of TAD2141 are already available; while certifications according to ISO26262 and ASIL are under preparation.

An automatic correction function considerably reduces the design-in effort. Moreover, the new angle sensor is equipped with a self-diagnostic function that detects not only an abnormality in the sensor itself, but also any abnormalities in the exterior environment, such as a power failure or loss of the magnetic field.
