Linear Actuators

New Standard for Sensitive Positioning

The Drive-Master Actuators are the standard for micro-positioning featuring:

  • Precise backlash free Micrometer Head

  • Non-rotating SpindleInterchangeable Tips

  • Optinal Piezoelectric Actuator Attachment

  • Integrated Hard Limit Switches (on 25 & 50mm extensions only)

  • 12 volt DC Servo Motor Drive

  • Computer Control Capable

The Drive-Master’s fine pitch drive spindle is ground to an accuracy better than 3µm per 25mm of travel. With the 16-line dual phase magnetic encoder and standard gear head, computer-controlled resolution is 0.05µm.Customer specified resolutions or slew rates can be achieved with a variety of gearing options. Accessories include ball-tip, radius-tip, flat-tip, and piezoelectric actuator end pieces. See Motor Controllers for computerized and stand alone drivers for these actuators.
