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. 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.
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
Compact, High-Precision, Cost-Effective
M-227 actuators provide a cost-effective solution for industrial and OEM environments.
Integrated Line Drivers
All actuators include an integral 0.5 m cable with 15-pin sub-D connector and come with a 3 m extension cable. On the DC servo versions, the connector 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 and see link).
For higher loads and integrated limit switches refer to the M-230 (see link), M-235 (see link) and M-238.
