General
Colour	Black

The Helavia A1x20-C rubber grommets from Ses-Sterling are black-coloured, flexible cable protection components specifically designed for use in installation technology and electrical systems. They serve as cable clamps for secure and tight fixation of cables in pass-throughs, e.g. in housing walls or enclosures. The grommets enable easy installation and ensure reliable mechanical holding as well as a certain level of protection against environmental influences. The designation A1x20-C indicates the specific version, where A1 refers to the size category and the number 20 indicates a nominal diameter of 20 mm. The black colour is standard and meets common requirements in industrial electrical installations.

Applications
The Helavia A1x20-C rubber grommets are used in electrical and IT installations, particularly where cables are routed through housings or wall pass-throughs. They are suitable for use in enclosures, control systems, machine construction and other technical installations where secure and tight cable routing is required. The grommets are designed for use at temperatures from -30 °C to 90 °C, making them suitable for a wide range of indoor and outdoor applications, provided environmental conditions remain within this temperature range. They are typically used in combination with cables having a diameter of approximately 20 mm, where the grommets adapt elastically to ensure a secure fit.

Functions and Features in Detail
The grommets are made of an elastic rubber material offering high flexibility and shape stability. The cable clamp function is achieved through the conical shape of the grommet, which automatically exerts a firm but non-damaging pressure when the cable is inserted. This prevents the cable from falling out and provides mechanical stabilisation. The black colour is not only aesthetic but also functional, as it is UV-resistant and therefore suitable for outdoor use, provided temperature limits are observed. The grommets are not designed for power supply via the cable (e.g. PoE), but are purely mechanical and protective in function.

Technology Explained Simply
The Helavia A1x20-C grommets operate on the principle of elastic clamping: during installation, the cable is passed through the grommet, where the conical shape wraps around the cable and, due to the elasticity of the material, creates a secure hold. The grommet adapts to the cable diameter, ensuring a tight and even encirclement. The material composition is chosen to provide high mechanical load capacity and resistance to mechanical stress. The grommets are not self-extinguishing, but they meet the requirements for mechanical safety in electrical installations. The specified temperature resistance of -30 °C to 90 °C indicates that the material maintains its function even under extreme temperatures, without deforming or failing.

Compatibility and Accessories
The grommets are universally applicable and compatible with cables having a diameter of approximately 20 mm. They can be used in various housing types, such as metal or plastic housings, provided the hole or pass-through is of sufficient size for installation. The grommets are not specifically designed for any particular brand or product series, but are to be understood as standard components for installation technology.

Installation and Mounting
Installation is performed by simply inserting the cable through the grommet and then placing it into the designated pass-through. The grommet elastically adapts to the cable and, due to its conical shape, creates a secure fit. No additional fastening or tools are required. The grommets are designed for single installation and are not intended for repeated disassembly. The packaging contains 100 pieces, suitable for larger installations or series mounting.

Operational Advantages
The Helavia A1x20-C grommets offer simple, fast and reliable cable fixation. The elastic adaptation to the cable prevents shifting or falling out, increasing the safety of the installation. The temperature resistance from -30 °C to 90 °C allows use in various environments, including industrial plants and outdoor areas. The black colour is robust and resistant to UV radiation, extending the service life of the grommets. They are easy to handle and require no special tools, reducing installation time and improving work efficiency.
