High-resolution linear actuator with stepper motor; 2-phase stepper motor with gearhead; 10 mm travel range; 20 N feed force; 1.5 mm/s maximum velocity; trapezoidal-threaded spindle; limit switches: Hall effect; 0.5 m cable length
M-228 • M-229 High-Resolution Linear Actuator with Stepper Motor
Compact and Particularly Inexpensive
- Travel ranges 10 and 25 mm
- High load capacity 80 N
- Resolution 0.36 nm with gearhead version
- Velocity to 4 mm/s
- Direct drive versions include handwheel
- Noncontact limit and reference switches





Compact standard-class linear drive
Stepper mike with 2-phase stepper motor as powerful direct drive, or slim design version with gearhead motors.
High-quality components
Nonrotating tip for uniform motion prevents wobble, torque, and wear at the point of contact. Noncontact limit switches protect the mechanics. A direction-sensing reference switch supports automation applications. Integrated position indicator. Versions with direct drive include handwheel for manual adjustment.
Inexpensive system solution
In conjunction with the networkable C-663.12 Mercury Step single-channel controller, the linear actuators offer good performance at an economically attractive system price for single-axis and multi-axis configurations.
