Pololu Glideforce GF23-120504-1-65 High-Speed LD Linear Actuator: 12kgf, 4" Stroke (3.9" Usable), 3.3"/s, 12V

This 12V high-speed light-duty linear actuator features a 5:1 gear reduction, capable of lifting loads up to 12 kgf (120 N) and handling static loads up to 30 kgf (300 N). It achieves a maximum speed of 84 mm/s at no load and 75 mm/s at maximum load. End limit switches enable easy control throughout its range of motion, and the shaft maintains its position when unpowered. This model offers a 10 cm stroke (9.9 cm usable) and does not include a feedback potentiometer.

Ideal for applications requiring rapid movement, this actuator is perfect for automating tasks in robotics, home automation, and industrial machinery. Its high-speed capability ensures efficient operation, making it suitable for projects where time is of the essence.

The built-in limit switches provide precise control, preventing over-extension and ensuring safety. The actuator's ability to hold its position without power is beneficial for energy-saving applications and scenarios where maintaining a position is critical without continuous power consumption.

With its compact design and robust load capacity, this actuator is a versatile choice for both hobbyists and professionals looking to integrate reliable motion control into their projects. Its simple operation and durability make it a valuable component in various mechanical systems.
