M-235 High-Resolution Linear Actuator with DC Motor

Highly Dynamic, High Forces up to 120 N

PI M-235.5DG
Travel ranges 20 and 50 mm
Min. incremental motion to 0.1 µm
Direct drive provides high velocities
Push / pull force capacity to 120 N
MTBF >10,000 h

Reference-class linear drive

Combines high precision, high forces, and high dynamics. Vacuum-compatible versions to 10-6 hPa are available

 

 

High-quality components

Recirculating ball screw provides high velocity and long lifetime. 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. A direction-sensing reference point switch supports automation applications. Closed-loop variants with differential encoder driver for a safe position signal transmission at distances up to 10 mm

 

Motor variants

  • Highly dynamic, closed-loop DC motors reach high velocities
  • Position-controlled DC motors with a gearhead and high-resolution rotary encoders allow for incremental motion of just 100 nm
  • Powerful and low-vibration 2-phase stepper motors allow for accurate positioning even without position control. With handwheel
