Notes The following options must beinstalled in the piezo transla- tors during the manufacturing process. They must be ordered with the piezo actuator and cannot be added later. If neces-sary contact your local PI officefor details on how to order modified translators. The P-177.10 option includesfactory calibration of any PI servo-controller (see “Piezo Drivers & NanopositioningControllers” section) deliveredalong with the sensor-equipped piezo translator.consists of a specially sealedsteel case with integrated flex- ure zones. Please call for dimensions and further details. The following translators are available with water-resistant cases: P-705.00 Positive Polarity All PI standard HVPZT transla-tors are negative polarity de-vices. The operating voltage isnegative; the case is positive/ GND. With the P-705.00 option HVPZTs can be operated with positive polarity. Case (GND) is negative (blacklead).Operating voltage is positive (red lead). P-706.00 Water-Resistant Case The water-resistant case is rec-ommended if PZTs are used in applications where spray of coolants, oil, water, etc. might damage the piezo ceramics. It

Piezos with strain gauge sensors are equipped with a 1 m PUR cable with FFA.0S.304.CLAC32 LEMO connector in addition to thevoltage cable. P-177.10 Strain Gauge PositionSensor for HVPZT Stack Actuators For positioning requiring highrepeatability and accuracy, the P-177.10 strain gauge position sensor manufacturer is available. See page 4-19 P-844.xx,P-845.xx,P-242. 30/40, P-243.30/40, P-246.xx, P-247.xx. Ball Tips To avoid bending moments andshear forces on the PZT ceram- ics, the translators are available with a ball tip instead of thestandard top piece. Dimensionsand part numbers are given in the drawings for the individual translators. P-702.20 Low-TemperatureRange (only for HVPZTs) P-703.20 UHV (for preloadedPZTs) -273°C to +80°C / -459°F to +176°F /0 K to 353 KGenerally all PZT ceramicsfunction down to zero kelvin. However, piezo translators areconstructed of a combinationof materials (ceramics, metal, insulating materials...) which makes the situation more complex.To qualify the piezoelectrictranslators for cryogenic tem- peratures, special insulation material and industrial adhesives must be used. The low-temperature translators are delivered as bare ceramic stacks withoutcase and mechanical preload.The electrical connection is via two 50 cm Teflon leads without industrial connectors. The piezo ceramics areenclosed in a stainless steelcase with vent holes. ThePZTs can be baked to 150°C. The electrical connection is via two 50 cm Teflon leads without connector. The nomi- nal displacement of the PZT is reduced by about 20% (due tothe stiff insulation materials).P-703.20 includes P-702.10 (high-temperature range) if ordered with HVPZTs.

Vacuum Options ExtendedTemperature Range

All PI piezo translators can be safely used in a vacuum out-side the range from 100 to 0.1 hPa (100 to 0.1 torr). See the “Tutorial: Piezoelectrics in Positioning” section, page 4-37for discussion. For appli- cations that require reduced outgassing, the P-703.10 and Standard HVPZTs work in thetemperature range from -40°C to 80°C (-40°F to +176°F). For applications requiring an extended temperature rangethe following options areavailable: P-702.10 High-TemperatureRange (only for HVPZTs) -40°C to +150°C / -40°F to +302°F / 233 K to 423 KSpecial electrical insulationmaterials are used. Connec- tion is via two 50 cm Teflonleads without connector. P-703.20 high-vacuum options are available. P-703.10 UHV (for non-pre-loaded PZTs) The translators are deliveredas bare ceramic stacks with- out a case. The PZTs can bebaked up to 150°C. The elec-trical connection is via two 50 cm long Teflon leads without connector. The nominal dis- placement of the PZT is reduced by about 20% (due to the stiff insulation materials). P-703.10 includes P-702.10 (high-temperature range) if ordered with HVPZTs.
