Additional cooling of the stainless steel casing - using compressed air or water, for example - can support heat dissipation from the dynamically operating actuator.
This enables working frequencies to be achieved that are ten times higher than with an actuator without casting compound (the P-885.95 can be run at 3.5kHz over the full travel range of 36µm, for example).
These multi-layer piezo actuators are available in sizes Ø 11.2mm × 40.5 mm for 30µm travel, and Ø 11.2 mm × 22.5mm for 14µm travel.
Higher forces can be achieved with a version measuring Ø 18.6 mm × 22.5mm providing a minimal displacement to 14µm. For these dimensions, the actuators with casting compound are available at short notice.
The actuators can be manufactured in other sizes to order.
