P-170 P-178 Open & Closed Loop Piezo Translators
- Displacement to 80 µm
- Pushing Forces to 2000 N
- Pulling Forces to 50 N
- Sub-msec Response
- Sub-nm Resolution
- Options: UHV, High & Low Temperature, Choice of End Pieces
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-178 models are equipped with thinner Piezo ceramic layers than P-170 to P-173 models, providing more displacement in the same package. On the other hand, the maximum operating voltage is limited to -1000 V.
Also, voltages in excess of -750 V are recommended only for short periods of time for the P-178 models.
The Piezo ceramic stack is protected by an aluminum case. Standard top piece is a magnet, standard bottom piece is a ferromagnetic steel flat. A variety of optional top and bottom pieces are available for ease of mounting. For push/pull forces up to 3 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, laser tuning, patch clamping, etc. (click here for details).
Accessories:
Extension cables & connectors.
