AS5410 3D-Hall Encoder absolute linear
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.
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 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. In order 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.
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.
The AS5410 is available in a 14-pin TSSOP package as well as and is qualified for an ambient temperature range
from -40°C to +105°C. It operates at a supply voltage of 3.3V +/-10%.
Absolute position sensing of 3D magnet trajectories
Insensitive to external magnetic stray fields (differential principle)
Up to 14-bit full scale resolution
33 point linearization
Programmable output characteristic
Configurable threshold position switch
SPI and PWM output
Re-configurable E²PROM on-chip
