Glideforce LACT2P-12V-05 Light-Duty Linear Actuator with Feedback: 15kgf, 2" Stroke (1.97" Usable), 1.7"/s, 12V

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 2-inch stroke (1.97″ usable) and a feedback potentiometer that lets you determine where the actuator is in its stroke.

The Light-Duty (LD) series of Glideforce linear actuators by Concentric International (formerly Iowa Export-Import) are 12V DC gearmotors that use a lead screw to move a shaft back and forth along its length. The shaft will hold its position even when unpowered and subjected to static loads up to 250 kgf [550 lbs or 2500 N] for the LACT versions and 30 kgf [67 lbs or 300 N] for the GF23 versions. Two limit switches safely stop the motor at either end of its range, while integrated diodes allow it to reverse direction after reaching a limit point if the supplied voltage is reversed. The actuators have an all-aluminum frame and extension tube, and the entire case is sealed to protect against dust and water (rated IP65).

Mounting brackets made from machined aluminum or stamped steel are available for attaching the actuators to a structure; two are required for each actuator (the aluminum brackets are sold individually while the steel brackets are sold in pairs).

Using the actuator

To test-drive the actuator, simply connect a power source of up to 12 V to the motor leads. Reversing the applied voltage will reverse the direction of motion. A motor controller or motor driver is required for electronic speed and direction control. We recommend our Jrk G2 21v3 or Jrk G2 24v13 motor controllers for use with the feedback actuators (see below for more information on this) and the Simple Motor Controller G2 18v15 for controlling the actuators without feedback, though many of our other motor controllers and motor drivers are capable of powering this actuator.

These actuators have a stall current of 7 A at 12 V, but they will, on average, draw far less than this when used within their load ratings. They draw around 1 A with no load and can exceed 3 A at their maximum rated dynamic load, so we have found they generally work well with our lower-power jrk 21v3 motor controller with feedback (see the bottom of this page for more information using this controller for closed-loop linear actuator position control). Note, however, that the actuators can briefly draw close to their full stall current when abruptly started or on a sudden change of direction. Such current spikes can be dampened if you take steps to limit the acceleration of the actuator (many of our motor controllers offer optional acceleration limiting).

Actuator leads

Actuators with feedback have a 24″ (60 cm) cable that is terminated with special female connectors as shown in the left picture below, one for the three potentiometer leads and another for the two power leads. These connectors match male versions on the extension cable for LD linear actuators. Actuator versions without feedback have a 36″ (90 cm) cable with two unterminated, stripped power leads as shown in the right picture below. Linear actuators without feedback do not have cables that are compatible with the linear actuator extension cable.
