LPA-100 Leveraged Piezoelectric Actuator
 Description
DSM's LPA-100 is a flexure-based piezoelectric actuator ideal for both dynamic and static applications where precise and accurate positioning is required. The LPA-100 is mechanically preloaded to ensure bi-directional operation, providing increased resilience to mechanical loads when compared to non-preloaded actuators. The mechanism design provides high-stroke operation in an exceptionally small package. The LPA architecture offers relatively high dynamic bandwidth capabilities for the nominal displacement range and mechanism size.
The LPA-100's compact design is well-suited to many applications and comes standard in a durable, non-corrosive stainless steel amplification frame with pre-tapped threaded mounting holes.
