The Latest Information on Piezoelectric Actuators is Available Here
P-243 P-247 Preloaded Open & Closed Loop EHL Piezo Translators
- Displacement to 120 µm
- Pushing Forces to 30000 N
- Pulling Forces to 3500 N
- Extremely High Stiffness
- Options: UHV, Low & High Temperature, Water Protected
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-247 models are equipped with thinner Piezo ceramic layers, providing more displacement than P-243 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.
Models P-247.xx, P-243.30 and P-243.40 come with a stainless steel case with internal spring preload protecting the Piezo ceramic stack. Models P-243.10 and P-243.20 come with an aluminum case, stainless steel end pieces and spring bolts providing the preload.
Application examples:
Precision machining, adaptive mechanics, vibration cancellation, smart structures, static and dynamic positioning of heavy parts, force generation for bending or compressing of material, etc. (click here for details).
