Multilayer Piezo Actuators

Multilayer piezo actuators are used in state-of-the-art diesel and gasoline injection systems to improve engine performance as well as reduce emissions and save fuel.

However, fast response and unrivalled precision are making piezo actuators likewise attractive for a number of further mechatronic tasks.

EPCOS is a leading supplier of customer-specific multilayer piezo actuator solutions. With many years of experience supplying the automotive industries at highest quality levels, EPCOS provides solutions in silver/palladium as well as copper technology.
