Selection Guide for CEDRAT's MLA Actuators

MLAs CEDRAT Multilayer Actuators (MLAs) are non-preloaded piezoceramics. As a consequence, they are NOT suited for high level dynamic operations (for high level dynamic operation we recommend pre-stressed actuators, DPA, PPA or APAs). Strain gauges ca be added upon request.
