PICMA® PLUS Stack Multilayer Piezo Actuators

NOUVEAU

Ceramic Insulated High-Power Actuators

Longer travel ranges
Superior lifetime
High stiffness
µs response time
Subnanometer resolution
UHV-compatible to 10^-9 hPa

Specific tips (tips and bases) can be mounted for mechanical coupling of the actuators. Possible designs are flat or spherical tips made of metal, ceramics, glass or sapphire. Application-specific tips can be manufactured on request.

PICMA® PLUS Stack actuators, dimensions in mm. For L, A, B, see data table.

For high dynamics applications, the multilayer actuators are equipped with electrodes for especially high currents of up to 20 A. Together with a high-power piezo amplifier such as the E-618, high operating frequencies in the kHz range can be attained. The rise times for the nominal displacement are a few tens of microseconds.

PICMA® multilayer actuators with all-ceramic insulated inner hole

General displacement behavior with control from 0 V to 100 V

Operating voltage -20 to 120 V. Ceramic insulation, polymer-free. Insensitive to humidity. Excellent temperature stability. UHV-compatible to 10^-9 hPa, no outgassing, high bakeout temperature. Ideal for dynamic operation. Flexible thanks to numerous designs. Encapsulated versions for operation in splash water or oil.

For high operating temperature up to 200 °C
Special electrodes for currents up to 20 A
Variable geometry: inner hole, round, rectangular
Ceramic or metal tips in many versions
Applied strain gauge sensors for positional stability
Available with optional connecting wires

Industry and research. Cryogenic environment with reduced displacement. For high-speed switching, precision positioning, active and adaptive systems, precision dosing.
