General
Colour	Black

The Helavia A3x25-C rubber grommets from Ses-Sterling are black-coloured, flexible protective sleeve elements for the installation of cables and lines in electrical and electronic systems. They serve as cable glands for secure and tight cable guidance through enclosures or control panels, providing mechanical protection against abrasion and sealing against dust and moisture. The grommets are specifically designed for use in industrial and technical environments where reliable cable routing and protective functions are required.

Applications
The Helavia A3x25-C are suitable for use in electrical installations, automation technology, and in machine and plant engineering. They are frequently used in enclosures, control systems, distribution boxes, or other closed housings to route cables through drilled holes. The grommets ensure a tight seal and prevent foreign objects, dust, or moisture from entering electrical components. Due to their temperature resistance of -30 to 90 °C, they are also suitable for applications in environments with varying climatic conditions.

Functions and Features in Detail
The rubber grommets are made of an elastic, black-coloured material that offers high flexibility and shape stability. The cable gland function is achieved through a conical shape, which ensures a secure fit and tight sealing when screwed into the hole. The grommets are designed to elastically adapt and securely fix cables of different diameters without damaging them. The black colour allows for discreet integration into technical installations and is typical for industrial applications.

Technology Explained Simply
The Helavia A3x25-C operate on the principle of a cable gland, where the cable is guided through a conically shaped opening. When the grommet is screwed into the hole, the cable is compressed laterally, creating a secure connection. This design ensures mechanical stabilisation of the cable and prevents it from being pulled out or shifting. The material composition ensures high elasticity and resistance to mechanical stress. The temperature resistance of -30 to 90 °C makes the grommets suitable for applications in indoor and outdoor environments, provided the ambient temperature remains within this range.

Compatibility and Accessories
The grommets are designed for holes with a diameter of 3 mm and can securely guide cables with a maximum diameter of 25 mm. They are compatible with standard holes in metal or plastic housings and can be used in various installation systems. Installation requires no additional tools or mounting aids; the grommets are simply screwed into the hole.

Installation and Mounting
The installation of the Helavia A3x25-C is done by simply screwing them into the designated hole. The grommet is screwed in deep enough to ensure a secure fit in the housing. The cable is then guided through the opening, where the elastic shape of the grommet enables a tight seal and mechanical fixation. The installation requires no special tools and can be quickly and safely performed by skilled personnel.

Operational Advantages
The Helavia A3x25-C provide reliable and tight cable routing, protecting against mechanical damage and environmental influences. The elastic material structure ensures a long service life and stable performance even under frequent movement or vibration. The temperature resistance of -30 to 90 °C expands the range of applications to various industrial and technical uses. The black-coloured design allows for discreet integration into technical installations.

The packaging contains 100 pieces, suitable for larger installations or series mounting. The weight specification of 0.525 g per piece is for logistical planning purposes and is not relevant to the functional description.
