General
Colour	Black

The Helavia A2Kx30-C rubber grommets from Ses-Sterling are black-coloured, flexible cable protection components specifically designed for use in installations where cables or lines are passed through drilled holes in panels, enclosures or wall claddings. These grommets serve as cable protection and prevent mechanical damage to the insulation as well as the ingress of dust or moisture at the penetration points. The designation A2Kx30-C refers to the specific version of the grommet, with the marking "C" indicating the black colour. The grommets are available in a pack of 100 pieces, making them suitable for series installations and larger projects.

Applications
These rubber grommets are suitable for use in electrical and IT installations, particularly in areas where cables are routed through metal or plastic plates. They are used in building installations, industrial plants, during the assembly of enclosures, in server rooms, or for machine cabling. The grommets protect cables from mechanical stresses such as friction, pressure or bending at the penetration points. Due to their flexible structure, they adapt to the respective drilled holes and ensure a tight, yet not overly tight, guidance of the lines.

Functions and Equipment in Detail
The Helavia A2Kx30-C grommets are made of an elastic rubber material that offers high flexibility and shape stability. The black colour is standard and corresponds to the marking "C" in the product name. The grommets are dimensioned to fit precisely into holes with a diameter of approximately 30 mm. The exact fit ensures that cables are securely guided without causing overstretching or damage to the insulation. The grommets are designed for temperature resistance from -30 °C to +90 °C, making them suitable for use in indoor environments and areas with moderate temperature fluctuations.

Technology Explained Simply
The grommets operate on the principle of a crimping bushing: they are inserted into a hole and surround the cable, with the elastic material adapting to the cable surface. This creates a mechanical hold that protects the cable from displacement and mechanical stress. The elastic expansion of the material allows cables of different diameters to be securely guided without damaging the insulation. The grommets are not self-cutting and must be inserted into an existing hole. The material composition ensures high resistance to mechanical stress and sufficient service life under normal operating conditions.

Compatibility and Accessories
The Helavia A2Kx30-C grommets are compatible with standard holes in the diameter range around 30 mm. They can be used with various cable types, such as electrical wiring, data cables or control lines. The use is in conjunction with panels, enclosures, wall claddings or other installation elements through which cables are routed.

Installation and Mounting
Mounting is done by simply inserting the grommet into the pre-drilled opening. The elastic structure ensures that the grommet adapts to the hole and securely holds the cable. No additional fastening or tools are required. The grommets are suitable for use on flat or slightly curved surfaces. Installation takes place before cable laying, with the grommet positioned so that the cable is securely guided after pulling through. The mounting is quick and does not require special expertise.

Operational Advantages
The Helavia A2Kx30-C grommets provide reliable cable protection through mechanical securing and protection against dust and moisture. The elastic structure ensures a long service life and secure cable guidance even under frequent movement or vibrations. The temperature resistance from -30 °C to +90 °C makes them suitable for a wide range of applications. The pack of 100 pieces enables efficient handling in larger installations. The grommets are easy to install and require no additional tools or fastening elements.
