The SMA3 bearingless absolute encoder can be installed in rotary and linear applications and integrates the Multipole Pitch Technology. It is designed for linear measuring lengths up to 19.3 m (63.32 ft) and shaft diameters greater than 6 m (19.685 ft) in a rotary application.
The Multipole Pitch Technology enables the SMA3 to have a pole pitch that can be adjusted in width. So, for example, the ring can be designed to perfectly fit the individual shaft and the size of the pole is adjusted to the resulting circumference. The SMA3 is designed in a compact IP67 protected readhead. Installation is easy thanks to the wide mounting tolerances larger than 1 mm. Working speed is up to 20 m/s. It is also equipped with a diagnostic LED.
