It consists of a preloaded ultra-low-friction, heavy-duty ballscrew which is driven by a 2-phase stepper motor or a closed-loop DC motor with motor-shaft-mounted, high-resolution encoder (2048 counts/ rev.). Non-Rotating Tip 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 heavy-duty industrial and OEM environments. They feature an extremely low stiction, low-friction construction, allowing for minimum incremental motion as low as 100 nanometers. The M-235.5DD version is equipped with a direct drive motor for high-speed positioning applications. Non-Contact Limit and Origin Switches Integrated, non-contact, high-precision Hall-effect origin and limit switches, protect your equipment and increase versatility in automation applications. Integrated Line Drivers M-235 actuators with DC motors include an integral 0.5 m cable with 15-pin sub-D 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-on ball tip and a flat tip are included. For smaller sizes and lower-duty applications, refer to the M-230, M-231, M-232 and M-227 and M-168 see link, see link and see link.
