Product description

The K-Series is stiffer than the DD-Series and the D-Series and has a higher resonance frequency, which gives it a shorter rise time.

Like the rest of the range it pairs a stacked piezoelectric actuator with a stroke magnification structure, though the magnification ratio here is smaller than on the DD-Series or D-Series. The body is flat and compact, and the output stroke is turned through 90 degrees relative to the stack's own direction. Applying a voltage makes the unit contract, as figure 2 shows.

Features

A high resonance frequency
A high blocked force
Fast response and a short rise time
Flat and compact
The output stroke of the piezoelectric actuator is turned through 90 degrees
It contracts under applied voltage, as shown in figure 2
The output direction is opposite to that of the KK-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 contract as in figure 2.
