The cable gland V-TEC VM L25 LGR from OBO Bettermann is a cable gland with metric connection thread in cap nut design, specifically designed for use in cable distribution boxes, enclosures, and distribution cabinets in private and industrial applications. The product enables a secure and durable connection between cables and enclosure walls, with integrated strain relief reducing mechanical stress caused by cable pull. The sealing lip ensures reliable sealing, preventing ingress of moisture and dust. The cable gland is tested in accordance with DIN EN 62444, a standard defining requirements for electrical safety and mechanical strength of cable glands.

Applications
The cable gland is suitable for use in electrical and electronic installations, particularly in environments requiring high mechanical load capacity and tight sealing. It is commonly used in distribution cabinets, enclosures, cable distribution boxes, and other housings operated indoors and outdoors. The operating temperature range extends from -20°C to +65°C, enabling use in a wide range of climatic conditions.

Functions and Equipment in Detail
The cable gland features a fully metric connection thread, ensuring precise and secure installation. The cap nut design allows for easy handling and secure seating in the enclosure. The integrated sealing lip provides tight sealing, preventing ingress of water and dust. The strain relief protects the cable from mechanical stress caused by pulling or bending forces. The cable gland is made of polyamide (PA), a robust plastic offering high mechanical strength and resistance to chemical influences.

Technology Explained Simply
The protection class IP68 means the cable gland is dust-tight and protected against continuous water ingress, including immersion. This makes it particularly suitable for outdoor use or in humid environments. Testing in accordance with DIN EN 62444 ensures the product meets requirements for electrical safety and mechanical strength. The temperature resistance from -20°C to +65°C allows use in a variety of environments, from cold warehouses to warm production facilities.

Compatibility and Accessories
The cable gland is suitable for cables with a diameter matching the connection thread M25. It can be used in combination with other products in the V-TEC system to ensure consistent and secure installation. The use of compatible cable distribution boxes, enclosures, and distribution cabinets is recommended to maximize functionality and safety of the installation.

Installation and Mounting
Mounting is performed by inserting the cable into the cable gland and then tightening the cap nut using an appropriate tool. The strain relief ensures the cable is not damaged during installation. The sealing lip provides tight sealing, preventing ingress of moisture and dust. The cable gland is designed for simple and quick installation, with the cap nut design enabling secure and precise mounting.

Operational Advantages
The cable gland offers high mechanical strength and reliable sealing, extending the service life of the installation. The strain relief protects the cable from mechanical stress, increasing the reliability of the connection. The protection class IP68 enables use in humid and dusty environments, increasing application flexibility. Testing in accordance with DIN EN 62444 ensures the product meets electrical safety requirements, enhancing installation safety.
