June 6, 2011 – austriamicrosystems introduced the AS5410 linear position sensor. The 3D Hall sensor solution senses absolute position in automotive & industrial applications and provides the highest resolution position information available.
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: for example, a travel distance of 40 mm does not pose a problem for a small, 4 x 4 x 3 mm NeFeB magnet. Moreover, the 3D Hall solution’s output remains stable even when the device is subject to external stray magnetic fields. 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 allows the AS5410 to convert a wide range of geometries, including curved movements, non-linear scales, and tilted chip/magnet geometries into a linear output signal. In order to achieve a perfectly linearized output of up to 0.5 % accuracy, the AS5410 linear position sensor provides an internal linearization table with 33 base points. With four preset basic operating modes which are selectable via SPI, the austriamicrosystems AS5410 3D Hall encoder offers quick and easy configuration. All signal conditioning is on chip, including compensation for temperature effects.
