Metal sealed type multilayer piezoelectric actuators
ASB Series（85˚C rated）, ASL series（150˚C rated）, AHB series（High
displacement model）
Outline
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
Features
allow use in various applications such as semiconductor
⃝ High reliability: Realization of MTTF＝36,000 hours
device production equipment and optical communication
equipment which require high reliability.
（at 85℃ and 100 V）
⃝
Easier installation into equipments thanks to the built-in
pre-load mechanism and mounting attachment
⃝ Minimum mechanical abrasion
Applications
⃝ Large generated force: 800 N
⃝Accurate positioning: Controllable in nm order
Fine adjustment of various X-Y tables steppers,
Mirror/prism positioning, Linear motors, Fluid flow
control valve drive, Vibration source, Manipulators,
etc.
