AUBURN, 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 switch speeds up the homing procedure and supports automation applications.
For vacuum-applications, special versions to 10-9 hPa are available. Resolution of 100 nm and repeatability down to 0.5 μm is achieved by a closed-loop servo motor for higher velocities or a micro-stepped 2-phase direct-drive motor. Other motor and encoder options for OEMs are available on request.
