What are actuators?

An actuator is a device that converts energy into motion or applies force. The mechanical device takes energy in the form of hydraulics, pneumatics, or from a motor, and converts it into motion. That motion can come in many forms, such as ejecting, blocking, or clamping. Actuators are used in manufacturing applications such as switches,
