Digital Linear Actuator Suits Fast, Precise Positioning Apps

High linear resolution as fine as 0.001"/pulse is said to be attained with the Series 92200 bidirectional linear actuator, a modified rotary stepper motor with a rotor that includes an internally molded thread that mates to an externally threaded shaft. Rotary motion is converted to linear movement, with the travel per step determined by the pitch of the lead screw and step angle of the motor. Energizing the unit's coils in the proper sequence causes the threaded shaft to move out of, or back into the rotor in precise linear increments. When power is removed, the actuator shaft remains in position.Weighing just 7 oz., the 12 models in the series are said to be well-suited for fast and precise positioning in medical, computer peripheral, office automation, HVAC and instrumentation applications. All devices are rated with a maximum linear force of 75 oz.
