P-239 Preloaded Open & Closed Loop Piezo Translators
- Displacement to 180 µm
- Pushing Forces to 4500 N
- Pulling Forces to 500 N
- Sub-msec Response
- Sub-nm Resolution
- Options: UHV, Low & High Temperature
Standard models are specifically designed for open loop operation. For highest accuracy, select the P-177.10 closed loop option integrating 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 ).
P-239 models are equipped with thin Piezo ceramic layers, providing displacement up to 180 µm at -1000 V operating voltage. For maximum lifetime, voltages in excess of -750 V are recommended only for short periods of time.
The Piezo ceramic stack is protected by a stainless steel case with internal spring preload. The standard translator tip and base have tapped holes. Select the P-239.95 ball tip option to help decouple off-axis or torque loads from the translator tip. For push/pull forces up to 5 N, the translator can be mounted by clamping around the case. For larger forces, the translator must be mounted by the base.
Application examples:
Static and dynamic positioning, optics, metrology, smart structures, precision machining, adaptive mechanics, vibration cancellation, switching, laser tuning, force generation for bending or compressing of material, etc. (click here for details).
