Ring Actuator 3 (CMAR03)
Noliac Plate Actuators
Noliac CMAR's are typically used when a low displacement at high force is required. Noliac CMAR's are cofired monolithic piezoelectric low voltage actuators that convert an electrical input to a very high-resolution linear movement at high force.
Noliac CMAR's are manufactured with ceramic layer thickness down to 20 µm as standard in order to allow very low operating voltage for full performance of the piezo material. Noliac CMAR's are mostly made to customer specifications, but a wide range of parts is available from stock as well.
