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 PI (Physik Instrumente).
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 52 mm (2 in.), pushing force of 30 0N (66 lb), and 50 mm/sec (2 in./sec) maximum velocity. The non-rotating 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 nanometers (0.1 microns) and repeatability down to 0.5 microns is achieved by a closed-loop servomotor for higher velocities or a micro-stepped 2-phase direct-drive motor. Other motor and encoder options for OEMs are available on request.
