50 mm Travel Range  0.05 µm Minimum Incremental Motion  < 0.5 µm Backlash  120 N Push/Pull Load  100 N Lateral Load Limit  Preloaded ultra-low Friction Ball Screw with Non Rotating Tip  Velocity to 3 mm/sec.  Closed-Loop DC Motor  Integrated Hall-Effect Limit Switches Application examples:  Quality control, test equipment, metrology, photonics packaging, fiber alignment. M-235 is an ultra-high resolution linear actuator providing linear motion of 50 mm with sub-micron resolution in a compact package. It consists of a preloaded ultra-low friction, heavy duty ballscrew driven by a closed-loop DC motor/gearhead combination with motor shaft mounted high resolution encoder (2048 counts/rev.).  Compared to conventional rotating tip micrometer drives the non-rotating tip design offers several advantages:  Elimination of torque-induced positioning errors  Elimination of sinusoidal motion errors  Elimination of wear at the contact point  Elimination of tip angle dependent wobble

M-235 actuators provide a cost effective solution for high duty industrial and OEM environments. They feature an extremely low stiction/friction construction allowing for minimum incremental motion of 50 nanometers at speeds up to 3 mm/sec. To protect your investment, M-235 actuators include integrated non contacting Hall-Effect limit switches. Each actuator includes an integral 0.5 m cable with 15 pin D-sub connector and a 3 m extension cable. The connector features integrated line drivers for cable lengths up to 10 meters between actuator and controller. A screw-in ball tip and flat tip are included. Stepper motor driven versions of the M-235 are in preparation. For smaller sizes and lower duty applications refer to the M-230 and M-227 datasheets.
