FPA-550E-HK Piezoelectric Actuator
Description
DSM's FPA-550E-HK is a flexure-based piezoelectric actuator ideal for both dynamic and static applications where precise and accurate positioning is required. The FPA-550E-HK is mechanically preloaded to ensure bi-directional operation, providing increased resilience to mechanical loads when compared to non-preloaded actuators. The actuator was designed to provide relatively high mechanical stiffness in order to provide 30 Hz dynamic bandwidth while carrying a static 125 lbf (550N) load (making position corrections for a telescope's primary mirror).
The FPA-550E-HK's compact design comes standard in a durable, non-corrosive stainless steel design pre-tapped with threaded mounting holes to match a customer's requirements.
