A linear actuator is a positioning device that provides motion in 1 degree of freedom. Designed for highly accurate and fast repetitive industrial applications, the L-239 compact linear actuator is the newest addition to the suite of motion control solutions available from precision positioning systems industry leader PI (Physik Instrumente).
High Quality Components, Built to Last
Equipped with precision ground ball screws for higher speed and a longer service life, the L-239 high force actuator has a positioning range of 52mm (2”), pushing force of 300N (66lbs), and 50mm/sec (2”/sec) 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.
Which Motor Do You Need?
Resolution of 100 nanometers (0.1 microns) and repeatability down to 0.5 microns 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.
