This 12 V light-duty (LD) linear actuator with a 5:1 gear reduction can lift loads up to 15 kgf [34 lbs or 150 N] and can withstand static loads up to 250 kgf [550 lbs or 2500 N]. It has a maximum speed of 43.9 mm/s [1.73″/s] at no load and 36.5 mm/s [1.44″/s] at the maximum load. Limit switches at each end make the actuator easy to control over its full range of motion, and the worm drive ensures that the shaft will hold its position even when unpowered. This version has a 12-inch stroke and no feedback potentiometer.
