The DV 12/18 strain relief from Ses-Sterling is a molded part made of polychloroprene rubber, specifically designed for use in electrical and IT installations. It serves as strain relief in cable routing applications, reducing mechanical stress on cables and wires at points of passage through enclosures, wall penetrations, or other components. The size DV 12/18 is designed for cables with a diameter of 12 to 18 mm, where the strain relief ensures that cables are not damaged by tensile forces, particularly during movement or vibration during operation. The product is finished in black, making it suitable for use in industrial and technical installations where a discreet yet robust design is required.

Applications

The DV 12/18 strain relief is typically used in electrical installations, automation technology, and IT infrastructure, where cables are routed through enclosures or wall penetrations. It is especially suitable for applications requiring mechanical protection against tensile stress, such as in machine building, plant engineering, or cabinet wiring. The use of polychloroprene rubber ensures high flexibility and resistance to mechanical stress, increasing the service life of the connection.

Functions and Features in Detail

The strain relief is designed as a cable gland that elastically adapts to the cable diameter. Its shape allows for secure and tight cable guidance, while the strain relief minimizes force transmission to the cable. The polychloroprene rubber material offers good chemical resistance and is suitable for industrial environments. The black color is not only aesthetic but also functional, as it reduces visibility in technical installations and facilitates integration into existing systems.

Technical Explanation

The DV 12/18 strain relief operates on the principle of elastic deformation: during installation, the cable is inserted through the gland, and the material conforms around the cable, creating a secure yet flexible connection. The strain relief acts as a buffer, transferring mechanical stress from the cable to the enclosure, thereby protecting the cable from cracks or breaks. The use of polychloroprene rubber ensures high elasticity and resistance to wear, which is particularly beneficial in applications involving frequent movement or vibration.

Compatibility and Accessories

The DV 12/18 strain relief is designed for cables with a diameter of 12 to 18 mm. It is used in conjunction with other molded parts from the HELAVIA series, which are also made of polychloroprene rubber. Compatibility with other HELAVIA series products enables uniform design of cable connections in complex installations.

Installation and Mounting

Installation is performed by simply inserting the cable into the gland. The elastic nature of the material ensures the cable is securely held without requiring additional fastening elements. The strain relief can be directly installed in wall penetrations, enclosures, or other housings. No special tools are required; installation can be done without auxiliary equipment. The strain relief is designed to adapt easily and provide a tight, flexible connection.

Operational Advantages

Using the DV 12/18 strain relief reduces the risk of cable damage due to mechanical stress, increasing the reliability of the installation. The strain relief contributes to a longer service life of cable connections, especially in environments with vibrations or movement. The polychloroprene rubber material offers high resistance to wear and chemical influences, enhancing safety in industrial applications. The black color supports seamless integration into existing systems without causing visual disruptions.
