HIGH SPEED RESPONSE PIEZO ACTUATOR WITH NANO ORDER RESOLUTION
The PZA series of piezoelectric linear actuators provide high-precision positioning control by stacking piezoelectric elements. 45 different models with 3 different forces, 5 different strokes, and 3 different tip shapes are available for all kinds of applications. This series is equipped with a strain sensor (strain gauge), enabling highly accurate displacement control. The metal package provides excellent environmental resistance. Combined with our piezoelectric controller (piezoelectric driver), it can easily perform nano-order position control by closed-loop control.

Specifications
Options
- N
-
No strain sensor (strain gauge).
- (BNC)
-
BNC connector for control cable.
How to Order
When ordering, add Option No. in the following order by the shape of the top piece, with or without strain sensor (strain gauge), and connector to Model No.
<Example> PZA12-1BN(BNC), PZA12-1TN, PZA12-1S(BNC)
ADDITIONAL PRODUCTS
- Extension cable
-
Extension cables up to 4 meters are available. Depending on whether the piezo actuator has a strain sensor, two types of extension cables are available. With a strain sensor, the set consists of a control cable and a sensor cable. Without a strain sensor, only the control cable is used. You can also change the control cable to BNC by specifying the connector. Cable length can be specified in 1-meter increments.
-
Cable type
• PZ extension cable: with strain sensor (set of control cable and sensor cable)
• PZN extension cable: without strain sensor (control cable only) -
Connector type (control cable only)
• Not specified: LEMO socket - LEMO plug
• LB: LEMO socket - BNC plug (male)
• BB: BNC jack (female) - BNC plug (male)
-
