The product You were Looking for was moved Click Here for new Address M-227 High-Resolution DC-Mike Actuators 10, 25 & 50 mm Travel Ranges 0.05 µm Minimum Incremental Motion Non-Rotating Tip Closed-Loop DC Motor Compatible with Leading Industrial Motion Controllers Sub-nm Resolution with Optional PZT Drive >5,000 Hours MTBF M-227 are ultra-high-resolution linear actuators providing linear motion up to 50 mm with sub-micron resolution in a compact package. They consist of a micrometer with non-rotating tip, driven by a closed-loop DC-motor/gearhead combination 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; it eliminates: Torque-induced stage platform tilt Sinusoidal motion errors Wear at the contact point Tip-angle-dependent wobble M-227 actuators provide a cost-effective solution for industrial and OEM environments. Based on the successful M-222/M-226 series which they replace, M-227 DC Mikes offer both improved specs and reduced costs. The combination of an extremely low stiction/friction construction and high-resolution encoder allows for a minimum incremental motion of 50 nanometers at speeds up to 1 mm/sec. Integrated Line Drivers Each actuator includes an integrated 0.1 m cable with 15-pin sub-D connector and a 3 m extension cable. The connec-tor features integrated line drivers for cable lengths up to 10 meters between actuator and controller. High-Resolution Piezo Option All models come with standard flat tips. A variety of other tips are also available, such as a piezoelectric tip featuring 20 µm travel with sub-nanometer resolution for dynamic scanning and tracking (see link). For mounting, the DC-Mikes are clamped around the 19 mm diameter section. High forces around the 16 mm diameter section would increase friction and reduce accuracy. Such forces must be avoided, as must be lateral forces on the tip. Stepper-motor-driven versions of the M-227 are available on request. For higher loads and integrated limit switches refer to the M-230 and M-235 (see link and see link).
