Ring Stack Actuator 1 (SCMAR01)
Noliac Ring Piezo Actuators
Noliac SCMAR's are typically used when a medium displacement at high force is required. Noliac SCMA's are stacks of cofired monolithic piezoelectric low voltage actuators that convert an electrical input to a very high-resolution linear movement at high force.
Noliac SCMAR's are manufactured with ceramic layer thickness down to 20µm as standard in order to allow very low operating voltage for full performance of the piezo material. Noliac SCMAR's are mostly made to customer specifications, but a wide range of parts is available from stock as well.
