General
Colour	Black

The Helavia DA 95/140/20 black is a cable gland made of polychloroprene rubber, manufactured by Ses-Sterling, and is designed for the secure and tight guidance of cables and lines through installation components such as switch cabinets, distributors, or enclosures. This rubber gland is specifically designed for use in electrical and IT installations, where mechanical protection and sealing against dust and moisture are required. The gland is black, making it suitable for use in industrial and technical environments where high visibility or uniform colour design is desired.

Cable glands are shaped parts used in electrical installations for guiding and protecting cables through holes in metal or plastic enclosures. The Helavia DA 95/140/20 black is designed for this purpose, with the designation DA 95/140/20 indicating specific dimensions: an inner diameter of 95 mm, an outer diameter of 140 mm, and a length of 20 mm. These dimensions enable precise fitting into standard holes and ensure secure cable guidance without mechanical damage. The gland is supplied in a pack of 100 pieces, making it suitable for larger installations or series mounting.

Polychloroprene rubber is the material used, an elastic, durable synthetic rubber known for its high mechanical strength, weather resistance, and chemical resistance. It is particularly suitable for use in industrial and technical installations, where the glands may be exposed to long-term stresses from temperature fluctuations, mechanical strain, or contact with various chemicals. The black colour is typical for technical components and supports visual integration into professional installations.

The gland is typically used in switch cabinets, distributors, control enclosures, or other electrical devices where cables must pass through the enclosure wall. It protects the cables from mechanical damage caused by sharp edges and simultaneously ensures a tight connection that prevents dust and moisture ingress. The use of cable glands is particularly important in environments with increased requirements for installation safety and reliability, such as in manufacturing industry, machine building, or building automation.

Functions and equipment in detail

The Helavia DA 95/140/20 black is a shaped part distinguished by its precise geometry and material quality. The inner surface is smooth and allows for frictionless cable guidance, while the outer surface ensures a secure fit in the hole. The length of 20 mm is sufficient to enable stable anchoring in the hole without the gland penetrating excessively into the enclosure. The gland does not require additional tools or mounting aids; it is simply inserted into the hole and holds securely due to elastic tension.

Technology explained simply

The gland is made of an elastic material that deforms slightly when inserted into the hole and then returns to its original shape. This elastic effect ensures a tight fit that protects against mechanical stress and environmental influences such as dust or moisture. The material polychloroprene rubber is particularly resistant to UV radiation, ozone, and temperature fluctuations, which extends the service life of the gland in various operating environments. The black colour is not only aesthetic but also functional, as it makes the gland easily identifiable in technical environments.

Compatibility and accessories

The Helavia DA 95/140/20 black is designed for holes with a diameter of 95 mm and fits into standard installation components with this hole size. It is part of the HELAVIA product range from Ses-Sterling, which includes various sizes and variants of cable glands. The gland is supplied in a pack of 100 pieces, making it suitable for larger projects or series mounting.

Mounting and installation

Installation is carried out by simply inserting the gland into the designated hole. The elastic shape of the material ensures that the gland self-fixes in the hole. No additional tools, adhesives, or fastening elements are required. The gland is designed to be pushed into the hole without tools and creates a secure, tight connection. Installation is quick and does not require special expertise.

Advantages in operation

The Helavia DA 95/140/20 black provides a reliable and durable solution for cable guidance in electrical and technical installations. The use of polychloroprene rubber ensures high mechanical stability and weather resistance, increasing the service life of the gland. The tight fit protects cables from mechanical damage and environmental influences, improving the safety and reliability of the installation. The pack of 100 pieces enables efficient use in larger projects, reducing installation time.
