KEMET AE 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 AE series actuators feature compact size and a wide variety of shapes for applications such as ultrafine positioning mechanism and drive sources.

Features

• Large generated force of 3,500N/cm2
• Operating temperature range from −25°C to +85°C
• High-speed response: Driving up to about 1/3 of self resonant frequency (in several ten kHz)
• Low power consumption: Can be retained at the leakage current state of 100 μA or less
• Very small size: 1/10 or smaller than conventional multilayer actuators
• RoHS/REACH compliant

Applications

• Typical applications include positioning, auto focusing of optical systems, pumps, mass-flow valves, vibration source, vibration controls, sensors, image stabilization of DSC, mirror/prism positioning, manipulators, motors and printer.
