FPA-550C Piezoelectric Actuator
 Description
DSM's FPA-550C is a flexure-based piezo actuator ideal for both dynamic and static applications where precise and accurate positioning is required. The FPA-550C is available standard with low voltage (150V) piezo material. The actuator incorporates a preload that enables bi-directional motion. The mechanism design is intended to provide a relatively high displacement range in a low-profile package. The displacement of the mechanism is transmitted through two parallel output plates with tapped attachment holes available in metric or English threads. Custom mounting conditions can be integrated into the design. The actuator's stainless steel construction can be prepared for vacuum compatibility upon request.
