High-load preloaded piezo P-844-845 with a maximum stroke of 90µm.
3000 N pressing force / 700 N pulling force, 90 µm movement with sub-nanometer resolution, µs response.
The P-844/P-845, which features a PICMA® multi-layer stack housed in a preloaded metal case, is a high-load piezo actuator that operates with a maximum stroke of 90 µm at sub-nanometer precision, enabling a maximum pushing force of 3000 N and a pulling force of 700 N. The P-845 type includes a built-in strain gauge sensor (SGS) that directly measures and provides feedback on the piezo movement, minimizing hysteresis and drift. The P-844 is the version without a sensor. *For more details, please download the PDF or contact us.*
