General
Colour	Black

The Helavia A4x30-M rubber grommets from Ses-Sterling are black-coloured 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 serve as cable protection and prevent mechanical damage to the lines, particularly from friction or sharp edges. The designation A4x30-M indicates the technical dimensions: an inner diameter of 4 mm and a length of 30 mm, with the "M" referring to the material type or mounting form. The grommets are made from a flexible, rubber-like material that adapts elastically and enables a secure, tight cable guidance.

Applications
These rubber grommets are suitable for use in various technical systems, particularly in electrical installations, automation technology and machine building. They are frequently used in enclosures, control systems, device housings or during wiring of electronic components, where mechanical protection for cables is required. The black colour blends visually into most technical environments and is suitable for industrial applications.

Functions and Equipment in Detail
The Helavia A4x30-M grommets are designed as cable clamps, meaning they elastically deform when inserted into a hole and then create a firm, pressure-tight fit. This ensures that cables are securely guided and cannot be dislodged by vibrations or movements. The grommets are designed for cables with a diameter of approximately 4 mm, with the exact fit achieved through the elastic expansion of the material. The length of 30 mm allows sufficient coverage of the hole to ensure stable fixation. The black colour is standard and corresponds to the usual configuration for industrial applications.

Technology Explained Simply
The grommets are made of an elastic, rubber-like material that compresses when inserted into a hole and then returns to its original shape. This effect ensures a secure, pressure-tight fit that protects the cable from mechanical stress. The elastic properties of the material allow adaptation to slight deviations in hole diameter and ensure a tight cable guidance. The use is therefore intended for normal indoor conditions.

Compatibility and Accessories
The Helavia A4x30-M grommets are compatible with holes in the diameter range around 4 mm, with the exact fit achieved through the elastic expansion of the material. They can be used in combination with other installation elements such as cable ties, screw terminals or enclosure accessories to achieve a complete cable installation. The grommets are available in a pack of 1000 pieces, making them suitable for large projects or series assembly.

Installation and Mounting
Mounting is done by simply inserting the grommet into the pre-drilled opening. During insertion, the material is elastically deformed and adapts to the hole. Subsequently, the cable is routed through the grommet, with the elastic recovery of the material ensuring a secure fit. The installation requires no additional tools or aids.

Operational Advantages
The Helavia A4x30-M grommets provide reliable mechanical protection for cables and lines, thereby extending the service life of the wiring. The elastic expansion of the material ensures a tight guidance that compensates for vibrations and movements. The grommets are easy to install and require no additional tools. The pack of 1000 pieces enables efficient use in larger installations. The black colour blends into most technical environments and is suitable for industrial applications.

The grommets are available in a pack of 1000 pieces, with a weight per piece of 1.02 g. The packaging weight is 1.02 kg. The EAN number is 3597470010204.
