Plate Bender 9 (CMBP09)
Noliac Ring Piezo Actuators
Noliac CMBP's are typically used when a large displacement at low force is required. Noliac CMBP's are cofired monolithic piezoelectric low voltage actuators that convert an electrical input to a very high-resolution bending movement at one end of a plate shaped actuator.
Noliac CMBP's are manufactured with ceramic layer thickness down to 67µm as standard in order to facilitate very low operating voltage for full performance of the piezo material. Noliac CMBP's are mostly made to customer specifications, but a wide range of parts is available from stock as well.
