Series PAHS – Description

The new PAHS piezo actuators achieve higher motion than a conventional actuator of similar length. With more than four times higher travel they are a perfect solution when space is limited but high resolution requirements exist.

PAHS actuators operate with the same voltage band of 150V and can therefore be easily integrated into existing systems using the same controllers.

Like PAHL piezo actuators, PAHS actuators have high blocking forces and can move large masses. Due to the integrated mechanical pre-load, they can work under tensile forces and in dynamic applications. They also have high resonant frequencies guaranteeing fast settling times.
