M-230 are ultra-high resolution linear actuators providing linear motion up to 25 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.). 

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
M-230 actuators provide a cost effective solution for higher duty industrial and OEM environments. They feature an extremely low stiction/friction construction allowing for minimum incremental motion of 50 nanometers at speeds up to 1.5 mm/sec.

To protect your investment, M-230 actuators include integrated non contacting Hall-Effect limit switches. Each actuator includes an integral 0.5 m cable with 15 pin D-sub connector and a 3 m extension cable. The connector features integrated line drivers for cable lengths up to 10 meters between actuator and controller.

A screw-in ball tip and flat tip are included.

Stepper motor driven versions of the M-230 are in preparation.

For higher loads and travel ranges refer to the M-235 datasheet
