DPT-E Closed Loop Piezo Actuators
Precision, Accuracy and Speed for the best in Nanopositioning.
The DPT-E range of actuators are designed with capacitive feedback control to give precise positioning.
A system comprising a DPT-E actuator with the fully programmable NanoScan NPC-D-6000 series or the NPC-D-5200 digital closed loop controllers are ideal for the most demanding applications . Capable of moving loads of up to 60 kg over the full travel range of up to 110 μm. with low electronic noise and high linearity, giving confidence that the actuator is positioned with precision, speed and accuracy. High thermal stability super invar construction gives superior position stability. The DPT-E is designed to be a direct replacement for the high voltage DPT-C it supersedes. The travel ranges have been increased by at least 25% from the DPT-C equivalent models as well as other enhancements.
Ultra-high vacuum (UHV) vacuum compatible models available as standard, and options for high-temperature, non-magnetic, and radiation environments are available on request. See datasheet for full details.
