M-230 High-Resolution Linear Actuator with DC and Stepper Motor

Nonrotating End Piece, Limit Switches

PI M-230
    • Min. incremental motion 0.05 µm
    • Travel ranges 10 and 25 mm
    • Nonrotating end piece
    • Velocity to 1.2 mm/s
    • MTBF >20,000 h
    • Closed-loop DC servo and stepper motor versions
    • Noncontact limit switches
    • Clamping or frontal mounting

Precision-class linear drive

Precision linear actuator. Vacuum-compatible versions to 10-6 hPa are available

High-quality components

Extremely low-friction and backlash-free construction. Nonrotating end piece for uniform motion prevents wobble, torque, and wear at the point of contact. Includes flat and spherical end piece for decoupling of lateral and tilt forces. Noncontact limit switches protect the mechanical system. Closed-loop variants with differential encoder driver for a safe position signal transmission at distances up to 10 mm

Motor variants

  • Position-controlled DC motors with a gearhead and high-resolution rotary encoders allow for incremental motion and repeatability of just 100 nm
  • Low-vibration 2-phase stepper motors with gearhead allow for smooth and accurate open-loop positioning
