The MP-21 linear actuator is designed for applications with very limited space conditions. Typical applications include actuation of manual drive stages and mirror mounts. It utilizes a 2-phase stepper motor and a mechanical limit switch for homing. Versions capable of operation in vacuum (10-6 mbar) are available. The MP-21 is compatible with the MMC-200 controller.
