3. Good mechanical properties: PET substrate has excellent mechanical strength, heat resistance, and chemical resistance, which can meet various requirements in industrial automation control systems.

2、 Application of PET silver plated film for electromagnetic shielding in industrial automation control systems

In industrial automation control systems, electromagnetic interference mainly comes from equipment such as motors, frequency converters, and switching power supplies. These devices generate a large amount of electromagnetic radiation during operation, causing interference to sensors, actuators, and communication lines in the control system. In order to ensure the stability and reliability of the control system, effective electromagnetic shielding measures must be taken.

1. Electromagnetic shielding of sensors

Sensors are an important component of industrial automation control systems, and their performance directly affects the accuracy and response speed of the control system. Sensors are usually installed near motors and frequency converters, which are susceptible to electromagnetic interference. usePET silver plated filmWrapping or covering the sensor can effectively shield external electromagnetic radiation and ensure the normal operation of the sensor.

2. Electromagnetic shielding of actuators

The actuator is another key component in industrial automation control systems, responsible for executing control instructions. The actuator is usually connected to the motor and frequency converter, and is susceptible to electromagnetic interference. Using PET silver plated film to wrap or cover the actuator can effectively shield external electromagnetic radiation and ensure the normal operation of the actuator.

3. Electromagnetic shielding of communication lines

The communication lines in industrial automation control systems are responsible for transmitting control instructions and feedback signals. Communication lines are usually long and susceptible to electromagnetic interference. Using PET silver plated film to wrap or cover communication lines can effectively shield external electromagnetic radiation and ensure the normal operation of communication lines.

3、 Advantages of PET silver plated film
