The Helavia A1x20-M rubber grommets from Ses-Sterling are black-coloured, flexibly applicable cable protection components specifically designed for use in installations where cables or lines are routed through drilled holes in panels, enclosures or other components. These grommets provide mechanical and electrical protection by shielding cables from mechanical stress such as friction or pressure, while simultaneously ensuring a secure, tight fit. The designation A1x20-M refers to the specific configuration of the grommet, with dimensions and fit designed for a particular hole size and cable thickness. The grommets are made from an elastic rubber material that offers high flexibility and shape stability to ensure a secure and tight fit.

Rubber grommets are widely used in electrical and IT installations, as they offer a simple yet effective method to protect cables and enable proper cable routing. The Helavia A1x20-M is particularly suitable for applications requiring a compact and robust solution, such as in the assembly of enclosures, control systems, or machine cabling. The black colour blends visually into most technical environments and is standard in the product line.

Functions and equipment in detail
The grommet is inserted into a hole in a component, with the cable routed through the central opening. The elastic material compresses around the cable, forming a tight, waterproof and dustproof connection. This prevents moisture, dust or other particles from entering the enclosure, thereby extending the service life of installed components. The grommet is designed to adapt to the shape of the cable without damaging it. The elastic expansion allows for secure routing even with slight variations in cable diameter.

Technology explained simply
The material technology used is based on a special rubber designed for high elasticity and resistance to mechanical stress. The grommet is rated for temperatures from -30 °C to 90 °C, making it suitable for use in a wide range of environments, from air-conditioned indoor spaces to industrial facilities with increased heat generation. The temperature resistance ensures that the material maintains its shape and function even under prolonged stress. The black colour is not only aesthetic but also functional, as it is UV-resistant and thus does not discolour or degrade even with prolonged exposure to sunlight.

The grommet is available in a pack of 1000 pieces, making it particularly suitable for large projects or series assembly. The weight of a single unit is 0.14 g, which facilitates handling and installation without compromising mechanical stability.

Compatibility and accessories
The Helavia A1x20-M is specifically designed for holes with a diameter of 20 mm and fits cables with a diameter of approximately 1 mm. The grommet is compatible with standard installation techniques and can be mounted without additional tools or accessories. It is inserted directly into the hole and adapts via elastic expansion. There are no specific accessories required for use; the grommet is designed as a single component and is directly integrated into the installation.

Installation and mounting
Mounting is done by simply inserting the grommet into the pre-drilled hole. The elastic construction ensures that the grommet automatically adapts to the shape of the hole and forms a secure, tight connection. The cable is then routed through the central opening of the grommet. It is important that the hole is clean and free of cracks or irregularities to ensure optimal fit. The grommet can also be used in multiple layers if a higher sealing level is required, although this is not part of the standard application.

Advantages in operation
The use of the Helavia A1x20-M provides a reliable, durable and maintenance-free solution for cable routing. The grommet protects the cable from mechanical damage, prevents ingress of foreign objects, and ensures proper cable routing. The high temperature resistance and UV resistance increase service life and reliability in various operating environments. The simple installation and high availability in large quantities make the grommet an economical solution for series and large-scale projects.
