Retracted length = 16.26 inches (413 mm), Extended length = 28.26 inches (717.8 mm) * Stroke length = 11.81 inches (300 mm) * Travel speed = 0.31 inches/sec (8 mm/s) * Maximum current draw = 4.6 Amps * IP65 rated (suitable for outdoor use) Linear actuators are actuators which create motion in a straight line. Unlike a motor, which creates circular motion, a linear actuator can be used with any application that requires moving something in a straight line.
