P-244, P-245 Preloaded Open & Closed Loop Piezo Translators
- Displacement to 120 µm
- Pushing Forces to 2000 N
- Pulling Forces to 300 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-245 models are equipped with thinner Piezo ceramic layers, providing more displacement than P-244 models in the same package. On the other hand, their maximum operating voltage is limited to -1000 V with voltages in excess of -750 V recommended only for short periods of time.
The Piezo ceramic stack is protected by an internally spring preload stainless steel case. The standard translator tip and base have tapped holes. Select the P-244.95 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.
For positioning of magnetic parts the P-176.10 Magnetic Adapter can be screwed into the translator tip.
