The angle sensor is equipped with a self-diagnostic function that detects abnormalities, such as a power failure or loss of the magnetic field.
TDK has introduced a new Tunnel Magneto Resistance (TMR) angle sensor that offers a guaranteed accuracy of ±0.2° and achieves an angle error of ±0.05° at room temperature.
Delivered with a digital output, the TAD2141 is capable of 360° contactless sensing within a temperature range of -40°C to 150°C. The automatic correction function, only available with the TAD2141, considerably reduces the design-in effort.
The angle sensor is also 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. Thanks to the integrated ASIC, the sensor is capable of digital output with all kinds of interfaces, such as SPI, Hall-Emulation (HSM), PWM and encoder (AZB). It also uses the ASIC design technology from ASIC design specialist ICsense, which TDK acquired in March 2017.
The main applications of the new sensor include industrial and robotics applications, as well as automotive applications focusing on future systems for automated driving.
Engineering samples of TAD2141 are already available, while certifications according to ISO26262 and ASIL are under preparation.
