Glideforce Medium-Duty (MD) Linear Actuators

The Medium-Duty (MD) 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. All of the actuators in this category have a 20:1 gearbox reduction with all metal gears, which allows them to move loads up to 100 kgf [225 lbs or 1000 N] and gives them a maximum speed of between 1.0 and 1.5 cm/s [0.4 and 0.6 in/s], depending on the load. The shaft will hold its position even when unpowered and subjected to static loads up to 450 kgf [1000 lbs or 4500 N]. 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).

Quantity:

This 10 ft (3 m) extension cable is designed to work with Glideforce light-duty and medium-duty linear actuators with feedback. It consists of five 20 AWG wires terminated on one end with male power and feedback connectors that securely snap into the actuator’s female power and feedback connectors. The other end has the same female connectors as the linear actuator’s cable; you can cut off these connectors and solder the five wire leads directly to your project, or you use crimp pins and crimp connector housings to make your own custom connector.
