Multilayer Piezoelectric Actuators – ASB Series Metal Sealed 85°C

User’s Guide

Fixing Method

• Carefully prevent the piezoelectric actuators from being bent, twisted or applied tensile force.

Reference: Twisting and Tension Tolerance

Reference Value

Remarks

Twisting Force 3 × 10

-1

N • m or less For an actuator which generates a force of

800 N (compression resistance).

Tension

50 N or less

• Install the actuator so that the center axis of the generated displacement is aligned with the center axis of the load.

• Select the mounting bracket (female thread type or ange 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 compresive force to the internal element by the metal case, avoid any usage that can

cause bending, twisting, or tension force when the device is in use.

Driving Method

• Connect the red lead wire to the positive (+) terminal of the power supply. Also prevent reverse voltage application.

• In driving applications, it is necessary to take consideration of hysteresis, ringing, creep, and other similar phenomenons. For pulse

driving, it is also necessary to be aware of self-heat generation, charge/discharge current, and the power supply’s impedance.

Generated force and load relation:

Static load: Initial position (0V position) is dropped

by spring constant but total displacement has the

same value under static load.

Spring load (Fluctuating load): Displacement

is changed by relation between generated

force and spring constant of actuator.

Static load: No load value change when actuator moves.

Fluctuating load: Load value changes by spring reaction when actuator moves.

Multilayer Piezoelectric Actuators – ASB Series Metal Sealed 85°C

Precautions

• Connect the red lead wire to the positive (+) terminal of the power supply.

• Avoid electric shocks 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.

• Avoid excessive physical shock. Otherwise, the internal piezoelectric ceramic

element may be damaged.

• If the actuator is exposed to high temperatures above 100°C or if used after

long storage periods (more than three months), the device should be polarized

by using the circuit conguration and conditions shown at right.

• Do not apply voltage exceeding maximum rating voltage, or rapid charging and

discharging.

• Do not use the actuator in high concentrations of highly inammable gas.

• Align the center axis of displacement of the actuator with the center axis of the mechanical load.

• When operated, the transient response time of the actuator should be less than 1/3 of the resonant frequency in order to prevent

damage by ringing.

• Store the metal sealed type (ASB series) preferably in a dry atmosphere (desirably below 40% RH) at ordinary temperatures (-5˚C to

+40˚C). Avoid condensation on the product’s surface.

• Store actuators where there is no vibration.

• Handle products properly as industrial waste. When disposing, please contact your local waste disposal service and make sure the

disposal methods meet all legal requirements.
