Metal sealed type multilayer piezoelectric actuators

Outline

Multilayer piezoelectric actuators convert electrical energy

into mechanical energy such as displacement or force

by making use of the piezoelectric longitudinal effect.

NEC TOKIN

ʼs 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,

etc.

ASB Series

（85˚C rated）,ASL series（150˚C rated）,AHB series（High

displacement model

）

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
