P-855 piezo translators are high-resolution linear actuators specially designed for integration in micrometer tips. They fit the M-227 DC-Mike motorized actuators (see link), the M-168 Stepper Mike (see link) motorized actuators and the M-631 to M-633 manual micrometers (see link).
The piezo translators consist of a monolithic PICMA® piezo ceramic integrated in a stainless steel housing.
P-855 actuators provide sub-millisecond response and sub-nanometer resolution.
Superior Lifetime with Ceramic-Encapsulated Piezos
Highest possible reliability is assured by the use of award-winning PICMA® multilayer piezo actuators. PICMA® actuators are the only ceramic-encapsulated PZT actuators on the market, which makes them resistant to ambient humidity and leakage-current failures. They are thus far superior to conventional actuators in reliability and lifetime.
