P-842, P-843 Preloaded Open & Closed Loop Piezo Translators
- Displacement to 90 µm
- Pushing Forces to 800 N
- Pulling Forces to 300 N
- Sub-msec Response
- Sub-nm Resolution
- UHV Option
P-842 is specifically designed for open loop operation. For highest accuracy, the P-843 closed loop version integrates ultra-high resolution strain gage position sensors for operation with PI servo control electronics (click here for details on Position Sensors and Closed Loop Operation ).
The translators are equipped with high reliability multilayer Piezo ceramic stacks protected by an internally spring preloaded non magnetic stainless steel case.
For push/pull forces up to 100 N, the translator can be mounted by clamping around the case. For larger forces, the translator must be mounted by the base. The P-176.50 Flexible Tip is available to protect the ceramics from bending forces.
Application examples:
Static and dynamic positioning, disk drive testing, optics, metrology, smart structures, precision machining, adaptive mechanics, vibration cancellation, switching, laser tuning, patch clamping, etc. (click here for details).
