Multilayer piezoelectric actuators are ceramic elements
for converting electrical energy into mechanical energy
such as displacement or force by utilizing the
piezoelectric longitudinal effect.
NEC TOKIN's multilayer piezoelectric actuators are
produced based on our unique element structure
design and using originally developed piezoelectric
ceramic materials with high electrostrictive factors.
Compared to conventional piezoelectric actuators,
they are smaller in size but can generate higher
displacement and force at low voltages.
Especially, the resin-coated AE series actuators
feature compact size and wide variety in shape for
applications such as ultra-fine positioning mechanisms
and drive sources.

Outline
Features
⃝ High reliability: Realization of MTTF ＝ 36,000 hours
（at 85℃ and 100 V）
⃝ Easier installation into equipments thanks to the built-in
pre-load mechanism and mounting attachment
⃝ Minimum mechanical abrasion
⃝ Large generated force: 800 N
⃝ Accurate positioning: Controllable in nm order
Numbering system
Multilayer piezoelectric actuators convert electrical energy
into mechanical energy such as displacement or force
by making use of the piezoelectric longitudinal effect.
NEC TOKINʼs multilayer piezoelectric actuators are
produced based on our unique element structure design
by making use of originally developed piezoelectric
ceramic materials with high electrostrictive factors.
Compared to conventional piezoelectric actuators,
they are smaller in size but can generate higher
displacements and forces at low voltages.
Especially, the metal sealed ASB/ASL and AHB
series actuators are much less influenced by ambient
humidity because of insulation from the atmosphere.
As a result, long service life and high performance
never experienced in the past have been attained to
allow use in various applications such as semiconductor
device production equipment and optical communication
equipment which require high reliability.
Applications
Fine adjustment of various X-Y tables steppers,
Mirror/prism positioning, Linear motors, Fluid flow
control valve drive, Vibration source, Manipulators,

Reliability
Majority of failure mode of multilayer piezoelectric actuators is the short circuit due to degraded insulation.
Though the cause of degradation of insulation has not been clarified perfectly, it has been found that the
failure rate varies greatly between statistic uses（DC voltage application）and dynamic uses（pulse voltage
application）. Like other electrical components, piezo actuators can be influenced by humidity as well as
applied voltage and ambient temperature. NEC TOKIN has added the metal sealed type piezo actuators
featuring high reliability by eliminating influence of the ambient atmosphere.
This section describes reliability guidelines for static and dynamic usages of the resin-coated and metal
sealed types actuators.
Reliability of our multilayer piezoelectric actuators is represented by MTTF（mean time to failure）in case of
static usage. Though the number of repetitions is considered to be used to represent the reliability in the
case of dynamic usage, the accurate relationship between the indicator and cause has not been determined
because of various influential causes and the mutual action between them. For the present, therefore, only
the obtained data and our concept are described.
（1）Resin-coated Type（AE Series）
a. DC voltage application
The acceleration factors have been obtained empirically for each of the drive voltage, ambient
temperature and relative humidity based on many experimental result. The MTTFr in actual
applications is estimated using equation（1）below with MTTFs observed under accelerated condition
as the reference value.
MTTF r=MTTF s×A v×A h×A t • • • (1)
MTTF r : Estimated value
MTTF s : Reference value (=500h)
A v : Acceleration factor for drive voltage=

V r : Actual voltage (V)

A h : Acceleration factor for relative humidity=

H r : Actual relative humidity (RH%)
Hr

T r : Actual ambient temperature(℃)
[Example] The following calculation is made for the case of use at 25℃, 60% RH and 100 V:
MTTF r =500×

=500×3.66×7.29×1.84
24,500h (2.8years)
b. Pulse voltage application
When this element is driven by a pulse voltage, temperature rises as a result of heating due to
dielectric loss of ceramics. Therefore, the element is not likely to be influenced by the humidity, thus
extending the service life greatly. Since this effect is affected by the element shape, pulse waveform
and frequency, it cannot be calculated by an equation as in the case of DC voltage application.
In NEC TOKINʼs testing on the AE0203D08, there was no failure confirmed after 0-150 V rectangular
pulse wave was applied with 500 Hz for 500 hours（equivalent to 900 million pulses were applied）.
Please pay attention to the physical damage due to ringing phenomenon caused by the fixed method
of the element and the speed of the voltage rise.
Please refer to the separately printed literature, “ NEC TOKIN Multilayer Piezoelectric Actuators Userʼs
Manual” for more detail.

（2）Metal Sealed Type（ASB, ASL and AHB Series）
a. DC voltage application
MTTFr of the metal sealed type under the actual operating conditions is calculated/estimated from the
reference MTTFs and the acceleration factor as in the case of the resin-coated type. However since
the internal element is sealed from the atmosphere, it is not influenced by the atmospheric humidity.
Therefore, equation（2）below is used.
MTTF r =MTTF s×A v×A t

MTTF s : Reference value (=36,000h)

b. Pulse voltage application
Like the resin-coated type, it is extremely difficult to estimate reliability by using an equation in the
metal sealed type because of the influence of the pulse waveform, frequency, etc. in addition to the
voltage and ambient temperature.
In NEC TOKINʼs testing on the ASB170C801NP0, there was no failure confirmed up to 1000 hours
（equivalent to 100 million pulses were applied）under the conditions below.

Guide to Use
Fixing Method:
⃝ Carefully prevent the piezo actuators from being bent, being twisted, or being applied tensile force.
Reference: Guide for tolerance of twisting and tension
Reference value
Twisting force
3 × 10 － 1N・m or less
Tension
50 N or less
Remarks
For an actuator which generates a force of 800 N
（compression resistance）
⃝ Install the actuator so that the center axis of generated displacement is aligned with the center axis of the load.
a. Resin-coated type
• Epoxy-based adhesives are recommended for bonding. Select adhesives that have high rigidity and
allow minimum thickness so that the generation force and displacement cannot be deteriorated. Also do
not form adhesives at the side of actuator.
• When thermosetting resin is used, perform polarizing treatment（see the caution section）again after the
adhesive is settled.
• The resin-coated type is weak to tensile force because of its structure and may be broken when tensile
force is applied onto the device. Using the device in the state that constantly applies compression is
effective against any mechanical damage. The pressure applied to this element should be kept at 20 to
50% of the force generated by this element（compression resistance）.
• Install the element so that the axis of generated displacement is vertical to the mounting surface.
b. Metal sealed type
• Select the mounting bracket（female thread type or flange type）according to the mounting method, and
install the element utilizing the bracket.
• Fix the element securely so that the generated force and displacement cannot be deteriorated.
• Connect the driven item at the displacement generating end after securing the mounting portion so that
it avoids unnecessary stress applied at the time of installation.
• Though this product is designed to apply a compressive force to the internal element by the metal case, avoid
any usages that cause bending, twisting, or tension force when the device is in use
Example of Actuator mounting：
Moving part or load
Moving part or load
Spherical surface
Hinge
Only one side is touching the actuator.
(Stress is concentrated on one edge
and generates share mode stress)
Piezo Actuator
The actuator may break.
a) Example of wrong mounting
Imperfect alignment between actuator and load
<Actuator will be broken>

b) Example of correct mounting
Mount the device so that the load is uniformly
applied by the spherical surface or the hinge
Driving Method:
⃝ Connect the red lead wire to the positive（＋）terminal of the power supply. Also prevent reverse voltage application.
⃝ Basically the voltage controls the aimed displacement and generated force. In driving, however, it is also necessary
to take ringing due to the resonance or hysteresis of the element itself into consideration. In pulse driving, it is further
necessary to pay sufficient attention to heat generation due to dielectric loss, charge/discharge current due to the
capacitive component and the power output impedance as well. Please refer to the separately printed
literature, “NEC TOKIN Multilayer Piezoelectric Actuators Userʼs Manual”

Precautions
⃝ Connect the red lead wire to the positive（＋）terminal of the power supply.
⃝ Carefully avoid electric shock since a high voltage is in use.
⃝ Never apply excessive tension to a lead wire. Do not handle the product by picking up or moving the lead wire.
⃝ Do not disassemble the case of the metal sealed type.
⃝ Machining of the actuator element and replacement of the lead wire are prohibited.
⃝ Do not handle the resin-coated type（AE series）with bare hands. Otherwise, the reliability of the element
would be degraded.
⃝ Do not wash resin-coated type（AE series）by organic solvant.
⃝ Avoid excessive physical shock resulting from, for example, dropping. Otherwise, the internal piezoelectric ceramic
element may be damaged.
⃝ If the actuator is exposed to high temperature above 100℃ or if it is used after long storage period（more
than three months）, it should be polarized by using the circuit configuration and conditions shown below.

⃝ Do not apply voltage exceeding maximum rating voltage, or do not do rapid charging and discharging.
These might lead to degradation of the reliability or mechanical fracture.
⃝ Do not use the actuator in high concentration of highly inflammable gas. Otherwise, ignition may occur.
⃝ Use the actuator so as not to cause bending, twisting or tension. Furthermore, align the center axis of displacement
of the actuator with the center axis of the mechanical load.
⃝ Drive the actuator so that the rising speed is more than three times as much as the resonance period in
order to prevent the device from damaging by ringing.
⃝ Store the resin-coated type（AE series）preferably in a dry atmosphere（desirably below 40% RH）at ordinary
temperatures（－ 5 to ＋ 40˚C）. Avoid condensation on the product surface.
⃝ Store actuators where there is no vibration.
⃝ These products must be handled properly as industrial waste. When disposing, please contact your local waste
disposal service.
⃝ Piezo actuator is industrial wastes, make sure disposal method under the laws.
