The cable gland V-TEC VM25 LGR from OBO Bettermann is a fully metric cable gland with metric thread connection in cap nut design, specifically designed for use in cable distribution boxes, enclosures, and distributor boxes in private and industrial applications. The product is made of polyamide (PA) and is finished in light grey (RAL7035). It features an integrated sealing lip and strain relief, ensuring a secure and durable connection between cable and enclosure. The gland is tested in accordance with DIN EN 62444, a standard that specifies requirements for cable glands used in electrical installations.

Applications
This cable gland is suitable for use in electrical installations, particularly in areas requiring high mechanical load capacity and protection. It is commonly used in distributor boxes, branch boxes, and other enclosures where cables must be securely and tightly introduced into the enclosure. The protection class IP68 makes it suitable for use in damp or wet environments, such as in industrial settings, outdoor applications, or installations with high environmental resistance requirements.

Functions and Equipment in Detail
The gland is equipped with strain relief, which prevents tensile forces from being transferred to the cable, which could cause damage or breakage. The integrated sealing lip ensures a tight seal between cable and enclosure, preventing ingress of dust, water, or other foreign objects. The cap nut design allows for easy and secure installation, with the thread directly mounted on the enclosure. The gland is suitable for cable diameters within the nominal size range of M25.

Technology Explained Simply
The term fully metric means that the thread is designed according to the metric system (M25), enabling universal use in various installation systems. The choice of polyamide (PA) material offers a good combination of mechanical strength, chemical resistance, and heat resistance. The protection class IP68 means the product is dust-tight and protected against continuous immersion in water, making it suitable for demanding environments. The operating temperature range of -20°C to +65°C covers a wide range of operating conditions, from cold outdoor areas to warm indoor spaces or industrial facilities.

Compatibility and Accessories
To complement the product, the accessory 116 M25 LGR PA lock nut light grey RAL7035 (item number 2048930) is available. This lock nut can be used for secure fastening of the cable gland in the enclosure, especially when additional stability or improved tightening performance is required. The combination of gland and lock nut enables optimal installation and increases the reliability of the connection.

Installation and Mounting
Installation is carried out by inserting the cable into the gland and then tightening the cap nut onto the enclosure. The strain relief ensures that the cable is not subjected to tension. The integrated sealing lip adapts to the cable diameter and ensures a tight seal. The gland is suitable for use in both metallic and non-metallic enclosures, provided the hole for the M25 thread is present.

Operational Advantages
The cable gland provides a reliable and tight connection that remains stable even under mechanical stress and in damp environments. The simple installation and use of standard threads facilitate the installation process. The material strength and high protection class IP68 ensure a long service life and low maintenance requirements. The operating temperature range of -20°C to +65°C makes the product suitable for a wide variety of application scenarios.
