  • 17 mm Travel Range 
  • 0.1 µm Minimum Incremental Motion 
  • Velocity to 2.5 mm/sec. 
  • Closed-Loop DC Motor 
  • Integrated Hall-Effect Limit Switches 
  • Fits M-105 & F-110 Fiber Aligners

Application examples: Photonics packaging, fiber alignment, quality control, test equipment, metrology.

M-231 is an ultra-high resolution linear actuator providing linear motion up to 17 mm with sub-micron resolution in a compact package. It consists of a lead screw driven by a closed-loop DC motor/gearhead combination with motor shaft mounted high resolution encoder (2048 counts/rev.). 

M-231 was especially designed to fit your existing manual translation stages (e.g. M-105) and F-110 piezoelectric fiber alignment systems as a direct replacement for a manual micrometer. 

M-231 actuators provide a cost effective solution for industrial and OEM environments. They feature a low stiction/friction construction allowing for minimum incremental motion of 100 nanometers at speeds up to 2.5 mm/sec.

To protect your investment, M-231 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.

Stepper motor driven versions of the M-231 are in preparation.

For higher loads and travel ranges refer to the M-227M-230 and M-235 datasheets.
