The materials used to make a waterproof linear electric actuator can vary depending on the manufacturer, the specific design, and the intended application. However, some common materials and features are often employed to ensure the actuator's waterproof and environmental protection capabilities:

1. Housing/Enclosure: The main body of the actuator is typically made from robust materials such as stainless steel, aluminum, or high-strength plastics. These materials offer durability, corrosion resistance, and protection against environmental elements.

2. Sealing Gaskets/O-Rings: To prevent water from entering the internal components, sealing gaskets or O-rings are used in critical areas such as the junctions between the housing parts, cable entry points, and openings for screws or bolts.

3. Coatings: Some actuators may have special coatings or surface treatments that provide additional protection against corrosion and environmental factors. For example, powder coating or anodizing can enhance the actuator's resistance to moisture and other harsh conditions.

4. Cable Conduits: If the actuator requires electrical connections for power and control signals, cable conduits or waterproof cable glands can be used to seal the entry points where cables enter the actuator, preventing water from seeping in.

5. Breather/Pressure Equalization Valve: In certain environments with significant temperature or pressure variations, a breather valve may be included to equalize the pressure inside the actuator, preventing the formation of condensation and maintaining the integrity of the seals.

6. Internal Component Encapsulation: Critical internal components, such as the motor, gearbox, and control electronics, may be encapsulated in a protective material or housed within waterproof compartments to shield them from moisture.

7. IP Rating: As mentioned earlier, the actuator's IP rating plays a crucial role in its waterproof and environmental protection capabilities. A higher IP rating ensures better resistance to water and dust ingress.

It's essential to check the product specifications provided by the manufacturer to understand the specific materials and features used in a particular waterproof linear electric actuator. Additionally, consider the intended application and environmental conditions to ensure the actuator is suitable for the specific requirements.
