PICMA® Actuators for maximum dynamics
For high-dynamics applications, the multilayer actuators are equipped with electrodes for especially high currents of up to 20 A. Together with a high-performance switching driver such as the E-618, high operating frequencies in the kHz range can be attained. The rise times for the nominal displacement are a few tens of microseconds.
PICMA® Multilayer actuators with ceramic-insulated inner hole
A new technology allows multilayer piezo actuators to be manufactured with an inner hole. Using special manufacturing methods the holes are already made in the unsintered actuator. As with the PICMA® standard actuators, the co-firing process of the ceramics and the internal electrodes is used to create the ceramic encapsulation which protects the piezo actuator against humidity and considerably increases its lifetime compared to conventional polymer-insulated piezo actuators. PICMA® stack actuators with an inner hole are ideally suited for applications such as fiber stretching.
PICMA® actuators with holes are manufactured on request.
High operating temperature of up to 200°C
For especially high-dynamics applications or high ambient temperatures, there are PICMA® multilayer actuator versions that can reliably function at temperatures of up to 200°C.
