Model 290 Linear Servo Actuator

Model 290 Linear Actuator

The Model 290 is one of the highestÌýperformance linear servo actuators availableÌýon the market. We offer this actuator with aÌýdigital communications interface. It providesÌý1,500 lbf at 0.26 inches / second for up to 7.75Ìýinch strokes. It has a homing sequence that determinesÌýend of travel on startup, thus, ensuring properÌýpositioning along its stroke. These featuresÌýallow our customer flexibility to have a drop-inÌýservo actuator for their system.
