CEDRAT PPA10M Parallel Pre-stressed Actuator

The parallel pre-stressed actuator is a preloaded stack of low voltage piezoelectric ceramics (MLA). The preload (or pres-stress) is obtained from an external spring frame made of stainless steel which protects the MLA against tensile force and provide mechanical interfaces for the user allowing for easier integration. This prestressing frame applies an optimal preloading force to the MLA which ensures a longer lifetime and better performance with dynamic applications than traditional preloaded actuators.

Designed by the CEDRAT Group, this new direct piezo Actuator results contracts carried out for CNES, the French Space Agency. The PPA model is lighter than the compacting Direct Piezo Actuator, which has the same electromechanical properties. Its compact size also makes integration easier in mechanical assembly.

The PPA10M is the smallest size version of the Parallel Pre-stressed Actuator M series.
