What is an Actuator?

Overview

This video explains what an Actuator is and how it plays a key role in industrial automation and control systems.

An actuator is a device that converts energy into mechanical motion, allowing machines and systems to move or operate.

It receives a control signal (from a PLC or controller) and uses energy such as electric, pneumatic (air), or hydraulic (fluid) to produce movement.

Actuators are considered the final control element in automation systems because they perform the actual physical action, such as opening a valve, moving a conveyor, or positioning a robotic arm.
