A medium-duty linear cylinder, it can lift loads up to 100 kgf (1000 N) and withstand a static load of up to 450 kgf (4500 N), the nominal extension of the actuator is 25 cm. The power supply voltage is 12 V. This version of the actuator has a built-in potentiometer for reading the position of the actuator or, for example, feedback implementations. Pololu 3618

A 12V DC linear actuator designed for precision automation, robotics, DIY projects, and light industrial applications. It offers a nominal stroke of 20 cm and a dynamic load capacity of up to 15 kgf, while maintaining static stability even without power. Built-in limit switches and a feedback potentiometer allow for safe and accurate piston position control, while the IP65-rated aluminum housing provides resistance to dust and moisture. The actuator operates smoothly and quietly at speeds up to 43.9 mm/s without load, and direction changes are achieved by reverse voltage polarity. Pololu 2323
