Product description

The DD-Series is a compact piezoelectric actuator that produces an output stroke more than ten times that of a multilayer stacked actuator on its own. It pairs a stacked actuator with a stroke magnification structure that overcomes the small displacement of the stack.

The body is flat and compact, so it uses space efficiently, and the output stroke is turned through 90 degrees relative to the stack's own direction. Applying a voltage makes the unit elongate, as figure 2 shows.

Features

A large output stroke
Flat and compact
The output stroke of the piezoelectric actuator is turned through 90 degrees
It elongates under applied voltage, as shown in figure 2
The output direction is opposite to that of the D-Series

Operating principle

Tapped holes are provided on both sides of the unit. The piezoelectric actuator carries red and black, or white, lead wires. Figure 1 shows a typical connection between the driver and the actuator; depending on the drive conditions a series resistor may be needed. Applying a voltage makes the unit elongate as in figure 2.
