# Linear Actuator with Feedback

This linear actuator is designed for **precise linear motion** in compact automation applications. Equipped with an internal **potentiometer for position feedback**, it allows for closed-loop control systems. The 75 lbs (≈ 333 N) force rating makes it suitable for light-to-medium load applications such as robotic arms, adjustable platforms, and smart enclosures.
