General
Colour	Black

The DG 48 membrane grommets from Ses-Sterling are black-coloured protective components made of polychloroprene rubber, specifically designed for use in electrical and installation technology. They serve as cable protection and cable entry elements in enclosures, switch boxes or other components, where cables or lines must pass through a wall or cover. The grommets ensure a tight seal and protect cables from mechanical stress, such as friction or pressure, as well as from environmental influences like dust or moisture. The designation DG 48 refers to the specific design and the corresponding hole size, intended for secure mounting in standard installation components.

Applications
The DG 48 membrane grommets are used in industrial electrical installations, machine building, and building automation. They are frequently employed in switch boxes, distribution boxes or control devices, where secure cable entry with simultaneous sealing is required. The use of polychloroprene rubber ensures high chemical resistance and resistance to ageing, making the grommets suitable for use in various environments, including mildly aggressive industrial settings.

Functions and Features in Detail
The grommets are designed as membrane grommets, meaning they feature a flexible, elastic membrane that adapts to the shape of the cable being passed through. This ensures a tight fit, allowing effective sealing even with cables of different diameters. The black colour is standard and corresponds to the usual configuration for industrial applications. The grommets do not include additional fastening elements or tools; they are mounted by simply pressing them into the designated hole.

Technology Explained Simply
The material used, polychloroprene rubber, is a high-quality elastomer known for its consistent elasticity and chemical resistance. It prevents moisture or dust from entering the interior of the enclosure, thereby protecting the function of electrical components. The grommets are not designed for use in extreme temperatures or under high mechanical loads, but for standard installation scenarios. The DG 48 design is intended for a hole with a 48 mm diameter, with the exact fit ensured by the elastic membrane.

Compatibility and Accessories
The DG 48 membrane grommets are designed for use in standard installation components, particularly in switch boxes and distributors featuring a 48 mm hole. They are part of the HELAVIA product line from Ses-Sterling and can be combined with other products from this series to ensure a consistent protection system. There are no specific accessories directly associated with this grommet; installation is performed without additional fastening elements.

Installation and Mounting
Mounting is done by simply pressing the grommet into the designated hole in the enclosure. The elastic membrane ensures the grommet adapts to the hole and creates a tight seal. No additional tools or mounting aids are required. The grommets are available in packages of 50 pieces, suitable for larger installations or series mounting.

Operational Advantages
The use of DG 48 membrane grommets ensures a long service life for cable entries, as the elastic membrane protects cables from mechanical damage while providing a tight seal. The material quality ensures high resistance to environmental influences, increasing the reliability of the installation. The simple, tool-free installation reduces installation effort and the risk of errors.
