3D linear position sensor for automotive & industrial apps

austriamicrosystems has introduced the 3D linear position sensor AS5410 to sense absolute position in automotive & industrial applications provides. This high resolution sensor solution is being demonstrated during the 2011 edition of the Sensors Expo & Conference in Rosemont, Illinois, booth #621 and SENSOR+TEST 2011, June 7-9, 2011 in Nuremberg, Germany, at Booth #528, Hall 12.

austriamicrosystems says the AS5410 allows absolute position sensing of a simple two-pole magnet immediately after starting up the device without the need for a prior reference run within the application. Position sensing is possible over large mechanical travel distances even with very small magnets: a travel distance of 40mm does not pose a problem for a small, 4 x 4 x 3 mm sized NeFeB magnet, for example, according to austriamicrosystems.

This sensor's output is not affected by external stray magnetic fields. austriamicrosystems claims this feature is a worldwide first and the result of a special differential measurement technique including several 3D Hall sensor elements.

Programming the internal EEPROM of the AS5410 allows to convert a wide range of geometries including curved movements, non-linear scales, and tilted chip/magnet geometries into a linear output signal. To achieve a perfectly linearized output (up to 0.5% accuracy), the AS5410 linear position sensor provides an internal linearization table with 33 base points. The preset basic operating modes are selectable via SPI. All signal conditioning is on chip, including compensation for temperature effects.

"The AS5410's unique differential architecture makes it perfect for use in position sensing applications that include not only dust, dirt and moisture but also unwanted magnetic fields," stated Bernd Gessner, Senior VP and General Manager business unit Automotive at austriamicrosystems. He continued, "The unique AS54xx family of 3D Hall magnetic encoder ICs is a fundamental addition to our current magnetic sensor product portfolio with a focus on both the automotive and industrial markets."
