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 configuration 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 inflammable 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.

When using our products, the following precautions should be taken:

●All specifications in this catalog and production status of products are subject to change without notice. Prior to the purchase, please contact NEC TOKIN for updated product data.

●Please request for a specification sheet for detailed product data prior to the purchase.

●Before using the product in this catalog, please read "Precautions" and other safety precautions listed in the printed version catalog.

● 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.

26 Multilayer Piezoelectric Actuators Vol.08

1. Safety designs allowing for failures of electronic components used in the system. In general, failures will occur in electronic

components at a certain probability. KEMET makes every effort to improve the quality and reliability of electronic component

products. However, it is impossible to completely eliminate the probability of failures. Therefore, when using KEMET’s electronic

component products, systems should be carefully designed to ensure the prevention of faulty operation and redundancy in the

event of an accident which would result in injury or death, fire, or social damage. Please refer to Precautions when using multilayer

piezoelectric actuators for more details of failures.

2. Quality level of various kinds of parts and equipment in which the parts can be utilized as electronic components have a standard

quality level unless otherwise specified. KEMET classifies the level of quality of electronic component products into three levels:

a standard quality level, a special quality level, and a custom quality level in which a customer individually specifies a quality

assurance program. Each of the quality levels has recommended applications. If a user wants to use the electronic parts having a

standard quality level in applications other than the applications specified for the standard quality level, they should always consult

a KEMET representative before using the electronic parts.
