Product description
The KK-Series is our high speed MechaTrans®. It 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 elongate, as figure 2 shows.
Watch the KK-Series in motion →Features
- A high resonance frequency
- High speed linear actuation
- 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 elongates under applied voltage, as shown in figure 2
- The output direction is opposite to that of the K-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.
