Pololu Glideforce MD122004 Medium-Duty Linear Actuator: 100kgf, 4" Stroke (3.9" Usable), 0.58"/s, 12V

The Glideforce Medium-Duty Linear Actuators are robust 12V DC gearmotors designed to move a shaft along its length using a lead screw mechanism. With a 20:1 gearbox reduction and all-metal gears, these actuators can handle loads up to 100 kgf (1000 N) and achieve speeds between 1.0 and 1.5 cm/s, depending on the load. The shaft maintains its position under static loads up to 450 kgf (4500 N) when unpowered. Built with an all-aluminum frame and extension tube, these actuators feature an IP65 rating for protection against dust and water. Integrated limit switches and diodes ensure safe operation and direction reversal.

These actuators are versatile, available in various stroke lengths from 10 cm to 30 cm, and can be equipped with optional potentiometers for feedback systems. This adaptability makes them ideal for applications requiring precise motion control, such as robotics, home automation, and industrial machinery.

The rugged construction and IP65 rating make these actuators suitable for outdoor and harsh environments, providing reliable performance even in challenging conditions. Their ability to hold position under load without power is a significant advantage in energy-sensitive applications.

For secure installation, mounting brackets made from machined aluminum or stamped steel are available. These brackets ensure that the actuators can be easily and securely attached to various structures, enhancing their usability in diverse settings.

Operating the actuator is straightforward: connect a power source up to 12V to the motor leads. Reversing the voltage changes the direction of motion. For electronic speed and direction control, a motor controller or driver is recommended. The actuators have a stall current of 14 A at 12V, but typically draw less under rated loads, averaging around 1 A with no load and up to 4 A at maximum dynamic load.

Actuators with feedback feature a 90 cm cable terminated with special connectors for easy integration with extension cables. Versions without feedback have a 90 cm cable with stripped power leads, offering flexibility in various applications.

For applications requiring precise control, the Jrk G2 motor controller is an excellent choice when paired with actuators featuring feedback. The controller's feedback capabilities enable fine-tuned motion control, making it suitable for complex automation tasks.
