General
Colour	Black

The Helavia DA 185/250/15 black from Ses-Sterling are penetration grommets made of polychloroprene rubber, specifically designed for use in electrical and installation technology. These grommets ensure safe and tight cable and wire guidance through components such as wall penetrations, enclosures, or control panels. The grommets are black and enable a clean, mechanically robust connection, with the material selection aiming for high flexibility and resistance to mechanical stress as well as environmental influences.

Applications
These penetration grommets are used in industrial electrical installations, machine building, building automation, and in the cabling of enclosures and control systems. They are particularly suitable for cable penetrations where a tight, pull-resistant, and simultaneously flexible guidance is required. The grommets are suitable for use in indoor and outdoor environments, with the material composition of polychloroprene rubber providing high resistance to UV radiation, ozone, and chemical influences.

Functions and Features in Detail
The grommets are designed as crimping nipples, which automatically create a secure, tight fit when the cable is inserted through the opening. The shape ensures even distribution of pulling forces and prevents cable shifting or loosening. The black color is standard and meets common requirements in electrical installation, where visual harmonization with other components is important. The grommets are available in a packaging unit of 100 pieces, making them particularly suitable for series installations and larger projects.

Technical Explanation
The designation DA 185/250/15 describes the geometric dimensions of the grommets: the first number (185) indicates the inner diameter in millimeters, the second (255) the outer diameter, and the third (15) the length in millimeters. These dimensions allow for precise fitting into standard penetrations and ensure secure cable guidance. The material polychloroprene rubber (PCP) is a high-quality elastomer that offers both elastic and mechanical load capacity. It is resistant to weathering, temperature fluctuations, and chemical agents, extending the service life of the grommets in demanding environments.

Compatibility and Accessories
The Helavia DA 185/250/15 black are compatible with standard cables and wires whose diameter falls within the specified range. They can be used in combination with other components from the HELAVIA series to ensure a consistent and professional cabling solution. The grommets do not include additional components such as fastening elements or sealing compounds; they serve solely as penetration elements.

Installation and Mounting
Installation is done by simply inserting the cable through the grommet opening. The design ensures that the grommet wall compresses during insertion, creating a tight, pull-resistant fit. No additional fastening or tools are required. The grommets can be easily installed into pre-drilled holes or penetrations, with the length of 15 mm sufficient to ensure stable anchoring.

Operational Advantages
The use of these grommets reduces the risk of cable damage due to mechanical stress or movement. The tight guidance prevents dust, moisture, or foreign objects from entering the installation, increasing the reliability and service life of the electrical system. The material strength and easy installation make the grommets a reliable solution for professional installations where durable and maintenance-free cabling is required.
