FPA-200C-HK Piezoelectric Actuator
 Description
DSM's FPA-200C-HK is a flexure-based piezoelectric actuator ideal for both dynamic and static applications where precise and accurate positioning is required. The FPA-200C-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 for the target stroke range for use in a tensioned structure vibration mitigation application.
The FPA-200C-HK's compact design is well-suited to many applications and comes standard in a durable, non-corrosive stainless steel design pre-tapped with threaded mounting holes to match a customer's requirements.
