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.

P/S piezo actuators have a hermetically sealed housing that allows for use in aggressive and humid environments. The construction of the housing tightly encloses the stack, also reducing mechanical play.

The M3 thread in the bottom plate allows for easy adaptation in existing systems and guarantees exact positioning.

Depending on the model, these piezo actuators offer motion from 18 µm up to 70 µm.

The PA, PA/T and PAHL series piezo actuators are all stack type actuators manufactured incorporating multilayer technology. They are internally pre-loaded with a mechanical spring, making them ideal for dynamic applications. The ability to generate a large force, and be subjected to high mass loading makes them particularly useful for machine tools and dynamic scanning systems. These actuators have a uniform diameter of either 14 or 20 mm depending on series. Strain gauge (SG) is used for closed-loop systems.

Piezo actuators should only be fastened with screws or clamps on the bottom plate of the actuator. During the installation and use, it is important not to subject the actuator tip to non-axial forces.

The actuator head is available in three versions: round head piece is standard, flat head option, and M3 thread on demand.

Series P and Series PHL piezo actuators are stack type actuators built in a multi-layer technique. PHL actuators are high-load. These P and PHL actuators both come without a pre-load, but they can still withstand a medium pressure force. PHL actuators are designed for high-load applications.

These piezo actuators are encased in a stainless steel housing.

P and PHL series actuators should be fastened with screws or clamps on the actuator’s bottom plate. These actuators are not designed for dynamic applications.
