An actuator, internationally known as an actor, represents an extremely versatile technical system that has a wide range of applications in various fields, particularly in automation technology. This information text provides a comprehensive insight into the functionality and applications of actuators.

How an actuator works:
An actuator converts an electrical input variable, usually a control signal, into a physical output variable using an auxiliary energy. This process makes it possible to convert electronic control signals into mechanical movements, such as those found in motors.

Different types of actuators:
1. electric actuators: these include electric motors that convert electrical energy into mechanical movement. Electric actuators are used in robotics, industrial production and automotive engineering.

2. hydraulic and pneumatic actuators: These use liquids or gases to perform mechanical movements. Hydraulic and pneumatic actuators are often used in heavy machinery and equipment.

3. piezoelectric actuators: Based on the piezoelectric effect, these actuators can perform precise movements and find application in areas such as micromechanics.

Intelligent properties of actuators:
1. sensor integration: active transponders can be equipped with sensors such as temperature probes to monitor environmental conditions.

2. autonomous functions: By integrating batteries, actuators enable autonomous functions that can be performed outside the direct scanner reading range.

Applications of actuators:
1. industry 4.0: actuators play a key role in the advanced automation of manufacturing processes.

2. robotics: electric actuators drive robot arms and movements.

3. automotive technology: In the automotive industry, actuators are used in vehicle control and drive systems.
