The P-212 and P-216 series are high-resolution linear piezo actuators (translators) for static and dynamic applications. They provide sub-millisecond response and sub-nanometer resolution.
These actuators have the friction-free, preloaded PICA™ Power actuators inside. The preload makes them ideal for dynamic applications like precision machining or active damping.
High Displacement with Ultra-High Reliability
PICA™ Power actuators are optimized for high-temperature working conditions and high-duty-cycle dynamic applications.
All PICA™ piezo ceramics are specifically designed for high-duty-cycle applications. With PI"s extensive applications knowledge, gained over several decades, performance does not come at the price of reliability. All materials used are specifically matched for robustness and lifetime. Endurance tests on PICA™ actuators prove consistent performance, even after billions (1,000,000,000) of cycles.
Open- and Closed-Loop Models for Optimum Dynamics and Linearity
The standard models are ideal for open loop positioning applications. In this mode the actuator displacement is roughly proportional to the applied voltage.
Open-loop operation is ideal for applications where fast response and very high resolution with maximum bandwidth are essential. Here, commanding and reading the target position in absolute values is either not important or carried out by external position sensors (see link).
For highest positioning accuracy and repeatability, select the factory installed closed-loop option with integrated ultra-high-resolution strain gauge position sensors and operate with PI servo-control electronics. For more information, read the tutorial "Piezo-electrics in Positioning" (see link ff).
Mechanical Mounting
Mounting is at the foot, with push/pull forces of less than 5 N, the actuator can be held by clamping the case. The optional ball tip is intended to decouple torque and off-center forces from the translator. Read details in Mounting and Handling Guidelines (see link).
High Flexibility with PI Amplifiers, Drivers & Controllers
PI offers a wide range of control electronics for piezo actuators from low-power drivers to the high-performance ampli-fier / controller E-481.
For closed-loop operation PI offers a wide variety of analog and digital controllers. The E-500 modular system can be easily upgraded from an amplifier to a servo controller, including different interface / display modules.
High-resolution amplifiers and servo-control electronics, both digital and analog, see selection guide in the "Piezo Drivers / Servo Controllers" section (see link ff).
