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. The shaft holds its position when unpowered. This version has a 4-inch stroke (3.9″ usable) and no feedback potentiometer.
