Request InfoPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsAUBURN, Mass., April 28, 2017 — The L-239 high-load linear actuator from Physik Instrumente LP provides motion in 1 degree of freedom. Designed for highly accurate and fast repetitive industrial applications, the L-239 compact linear actuator is equipped with precision ground ball screws for higher speed and a longer service life. It has a positioning range of 52 mm, a pushing force of 300 N, and 50-mm/s maximum velocity. The nonrotating tip enables uniform motion as it prevents wobble, torque and wear at the point of contact. Noncontact limit switches protect the mechanics, while a direction-sensing reference point...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2023 IssueSteering MirrorsPiezo and voice-coil steering mirrors from Physik Instrumente LP are designed for free space optical communications.
