General
Colour	Black

The Ses-Sterling Helavia DG M25 black is a membrane grommet made of polychloroprene rubber, specifically developed for use in electrical and installation technology. It serves as a protective and guiding element for cables and lines, particularly in connection areas to devices, enclosures or housings, where a tight and at the same time flexible seal is required. The grommet is black and supplied in a pack of 100 pieces, with a weight of 4.7 g per individual unit.

Applications
The membrane grommet DG M25 is primarily used in industrial electrical installation, machine building, as well as in building and plant automation. It enables secure and weather-resistant cable routing through enclosure walls or covers, with the elastic membrane providing a tight seal against dust, moisture and small particles. Due to the material polychloroprene rubber, it is suitable for use in environments with increased requirements for chemical resistance and mechanical load capacity.

Functions and Equipment in Detail
The grommet features a special membrane structure that elastically conforms around the routed cable, creating a tight seal. The design allows for easy installation and secure fixation in the enclosure. The black color is standard and visually matches industrial and technical environments. The grommet is not designed for power supply via cable (PoE), but is purely mechanically and protection-oriented designed.

Technology Explained Simply
The material base of polychloroprene rubber (PCP) offers high elasticity, weather resistance, and chemical resistance against many industrial chemicals. The membrane shape ensures that the cable is automatically guided into the correct position after routing and achieves a tight fit. The grommet is not designed for extreme temperatures, but is suitable for typical operating environments in electrical and automation technology.

Compatibility and Accessories
The membrane grommet DG M25 is designed for use with cables and lines that fit into the bore of the grommet. The exact fit is achieved by the elastic membrane, which adapts to the diameter of the cable. The grommet is used in conjunction with electrical devices, enclosures or machines where tight cable routing is required.

Installation and Mounting
Mounting is done by simply inserting the grommet into the designated hole in the enclosure. The cable is then routed through the membrane, where the elastic structure automatically creates a tight seal. No additional tools or mounting aids are required.

Operational Advantages
The membrane grommet provides reliable sealing against dust and moisture, increasing the service life of installed electrical devices and cables. The easy installation and high mechanical stability of the material ensure quick and secure installation. The use of polychloroprene rubber ensures long durability under normal operating conditions.
