 High Precision Actuators with Closed-Loop Feedback Motor by Physik Instrumente

Manufacturer legacy M-221–M-226 description: micrometer screw, non-rotating tip, servo motor, gearhead and motor-shaft feedback encoder. Technical-data table separates design resolution, minimum incremental motion, repeatability and backlash. The body's0.50mm/100/500 calculation is explicitly original ideal geometry, not a product specification or recommendation.
