General
Colour	Black

The Helavia DA 120/200/30 black from Ses-Sterling are cable glands made of polychloroprene rubber, designed for use in electrical and installation technology. These rubber glands ensure safe and tight cable or conduit guidance through components such as enclosures, wall penetrations, or switch cabinets. The glands are black in colour and enable clean, professional cable routing, while simultaneously providing mechanical protection and sealing against dust and moisture. The designation DA 120/200/30 refers to the technical dimensions: a diameter of 120 mm, a total length of 200 mm, and a bore width of 30 mm, enabling use with larger cable bundles or multiple conductors.

Applications
These cable glands are used in industrial electrical installations, machine building, building automation, as well as in the cabling of enclosures and control systems. They are particularly suitable where tight and flexible cable routing is required, for example when passing through metal or plastic enclosures. The use of polychloroprene rubber ensures high chemical resistance against oils, greases, and other industrial chemicals, making the glands suitable for demanding environments.

Functions and Features in Detail
The glands are designed as cable clamps, meaning they form a secure, tight connection to the penetration material through elastic deformation during installation. The elastic structure of the polychloroprene rubber ensures that the glands adapt to the shape of the bore and provide a lasting seal. The black colour is standard and visually matches most technical environments.

Technology Explained Simply
The rubber glands are made of polychloroprene rubber, an elastic, weather-resistant material that withstands both mechanical stress and chemical influences. The specific shape of the glands – with a bore width of 30 mm – allows flexible adaptation to different cable diameters. The total length of 200 mm ensures that the glands can be inserted sufficiently deep, even in larger bores or deep penetrations. The elastic deformation during installation ensures a secure, tight connection that protects against ingress of dust, moisture, or small particles.

Compatibility and Accessories
The Helavia DA 120/200/30 black are compatible with a wide range of components featuring a bore diameter of approximately 120 mm. They can be used in combination with other installation elements such as cable protection conduits, switch cabinets, or machine enclosures. The glands are individual components intended for integration into existing installations.

Installation and Mounting
Installation is carried out by simply inserting the glands into the designated bore. The elastic structure of the material ensures that the glands automatically adapt to the bore shape and create a tight seal. No additional fastening or tools are required. The glands are designed for single-use installation; reuse is not intended, as the elastic shape is altered after installation. The packaging contains 100 pieces, which is sufficient for larger installations or series mounting.

Operational Advantages
The use of these cable glands ensures durable, tight, and mechanically stable cable routing. The material quality of polychloroprene rubber ensures high service life and resistance to environmental influences. The tool-free installation reduces installation effort and error susceptibility. The glands contribute to safety by preventing foreign objects from entering electrical systems, which is particularly important in industrial applications. The standardised shape and dimensions simplify planning and procurement for series installations.
