  • The product name: Precision Positioning Stage PPS-20SM
  • Product model: PPS-20SM
  • Views : 12

The PPS-20 Stepper Motor version is suitable for applications requiring high speed and high blocking force. Miniature crossed roller bearings assure high stiffness and guiding accuracy for loads up to 20 N (horizontal orientation). It utilizes a 2-phase stepper motor resulting in high speed (> 4 mm/s) and high blocking force (> 10 N). The PPS-20SM is available in open loop or with an external encoder. Resolutions of 100 nm are achievable. Versions capable of operation in vacuum (10-6 mbar) are available. The PPS-20SM is compatible with the MMC-200 controller.
