The PPS-20 is a high-precision, long travel linear piezo stage. Miniature crossed roller bearings assure high stiffness and guiding accuracy for loads up to 20 N (horizontal orientation). It utilizes our patent-pending multi-phase piezo motor resulting in high speed (> 2 mm/s) and high blocking force (> 2 N). The PPS-20 is available in open loop or with an external encoder. Closed-loop resolution of 2 nm is achievable. Versions capable of operation in vacuum (10-9 mbar) and/or cryo (4 Kelvin) are available. The PPS-20 is compatible with the MMC-100 and MMC-110 controllers.
