M-231 is an ultra-high resolution closed-loop servo motor 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).
The M-231 compact closed-loop linear actuator was especially designed to fit compact translation stages (such as the M-105) and F-110 piezoelectric fiber alignment stages as a direct replacement for a manual micrometer. See this overview for additional miniature precision linear stages.
M-231 high precision linear 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.
Cost efficient stepper motor actuators are also available.
For higher loads and travel ranges, refer to the M-227, M-230 and M-235 datasheets.

PI also makes high speed linear actuators based on linear motors and voice coil motors.
