The DMS M16 double membrane bushing from Spelsberg is a protective bushing for the installation of cables and conduits in wall penetrations. It provides a secure and watertight connection between indoor and outdoor areas, particularly in installations exposed to high environmental stress. The bushing is made of thermoplastic elastomer (TPE), a material known for its elasticity, weather resistance, and chemical resistance. The grey colour matches the standard for electrical installation components and ensures unobtrusive integration into technical systems.

Applications

The DMS M16 is designed for wall penetrations in buildings and technical installations where a high degree of protection against dust and water is required. It is particularly suitable for outdoor use, in humid rooms, or in industrial environments where cable protection and sealing are of high importance. The protection rating IP66 ensures that the bushing is dust-tight and protected against heavy splashing water and water jets. This makes it suitable for installations in areas with increased humidity or direct weather exposure.

Functions and Features in Detail

The bushing features two sealing membranes that provide double sealing. This construction increases the reliability of the seal and prevents moisture or dirt from entering the interior of the wall or device. The membranes are closed, meaning they are not pierced by cables or conduits, but the cables are routed through the membranes, creating a tight fit. The sealing range is 5 to 9 mm, allowing use with cables within this diameter range. The wall thickness for which the bushing is designed is between 1.5 and 4.5 mm, making it suitable for a variety of building materials such as plasterboard, wood, or lightweight metal sheets.

Technology Explained Simply

The TPE (thermoplastic elastomer) material offers a combination of rubber elasticity and thermoplastic processability. It is flexible, resistant to UV radiation and temperature fluctuations, and enables a tight fit against both the wall and the cable. The protection rating IP66 means the bushing is dust-tight (IP6X) and protected against heavy splashing water (IPX6). This is particularly important when the bushing is installed outdoors or in humid indoor areas. The dimensions of the bushing are 20.7 mm (width) × 20.7 mm (height) × 13.2 mm (depth), making it compact and easy to install.

Compatibility and Accessories

The DMS M16 is designed for use with cables having a diameter of 5 to 9 mm. It is designed for wall thicknesses of 1.5 to 4.5 mm, making it suitable for a wide range of building materials. Use in combination with other products from the Spelsberg product line, especially in cable protection and wall penetration systems, is possible.

Installation and Mounting

Installation is carried out by inserting the bushing into a correspondingly sized hole in the wall. The wall thickness must be between 1.5 and 4.5 mm to ensure a secure and tight connection. The cables are routed through the two sealing membranes, creating a tight fit. No additional sealing or adhesive is required, as the membranes themselves provide the sealing. Installation is tool-free, as the bushing is elastic and adapts to both the wall and the cable.

Operational Advantages

The DMS M16 provides a reliable and durable seal that remains effective even under difficult environmental conditions. The double membrane structure enhances sealing security, and the TPE material ensures a long service life. The IP66 protection rating makes the bushing suitable for outdoor use without requiring additional protective measures. The compact design and tool-free installation simplify the installation process and reduce installation time. The grey colour ensures unobtrusive integration into technical installations.
