KEMET AER series resin coated multilayer piezoelectric actuators

Multilayer piezoelectric actuators are ceramic elements used to convert electrical energy into mechanical energy such as displacement or force by utilising the piezoelectric longitudinal effect.

KEMET’s multilayer piezoelectric actuators are produced based on our unique element structure design and 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.

The Resin Coated, Ring Shape AER series actuators feature compact size for applications such as ultra-fine positioning mechanism and drive sources.

Features

• Ring shape
• Operating temperature range from −25°C to +85°C
• High-speed response: Driving up to about 1/3 of self-resonant frequency (in several 10kHz)
• Low power consumption: Can be retained at the leakage current state of 100 μA or less
• RoHS/REACH compliant

Applications

• Typical applications include positioning, actuating, control and phase shift of laser. Since the laser can be passed inside the piezo ring, it can be used to adjust the phase and wavelength of the laser.
• Semiconductor manufacturing system, precision machinery, mechatronics, optical equipment, communications, medical equipment and measuring instruments are just a few examples where these products can be used.
