AUBURN, Mass. — Microsecond response, subnanometer resolution and low operating voltage makes PICMA actuators from PI (Physik Intrumente) LP suited to motion tasks in optics, semiconductors, photonics and engineering.
The P-080 tubular piezo stacks come in displacement ranges of 5, 11 and 25 μm with blocking force up to 850 N. Based on solid-state motion effects, the devices are used in applications that require high speed, high force and virtually unlimited resolution.
The through-hole of the P-080 is suitable for preloading or as an aperture for optical applications.
Tubular stacks feature the advantages of stack actuators and the versatility of piezo tubes, but with greater robustness, higher stiffness and longer travel ranges. A ceramic encapsulation process provides durability and reliability.
