The DMS M20 double membrane gland from Spelsberg is a closed, watertight cable entry element made of thermoplastic elastomer (TPE) for installing cables and conduits through walls or components. It is specifically designed for wall thicknesses between 1.5 and 4.5 mm and offers a sealing range of 7 to 13 mm, making it flexible for various cable diameters. The grey version blends visually into technical and industrial environments. With a protection rating of IP66, the gland is dust-tight and protected against heavy splashing water, making it suitable for outdoor use or in damp indoor areas.

Double membrane gland is the term for a component that provides double sealing through two sealing membranes. This construction increases the reliability of the seal and prevents moisture or dirt from entering the wired installation. The two membranes are arranged inside the gland and ensure secure sealing even during movements or vibrations during operation.

Technology explained clearly – The gland is made of thermoplastic elastomer (TPE), a flexible, durable plastic that adapts well to the shape of the wall while ensuring a tight seal. The material choice ensures high mechanical strength and chemical resistance against many industrial environments. Dimensions are 25.2 mm (width) × 25.2 mm (height) × 13.4 mm (depth), enabling compact installation. The IP66 protection rating means the device is dust-tight and protected against splashing water from any direction, even heavy spray – making the gland suitable for outdoor installations or damp indoor areas.

Applications – The DMS M20 is typically used in electrical installations, building automation, industrial control technology, or manufacturing technology, where secure and tight cable passage through walls is required. It is particularly suitable for applications requiring high mechanical stress or moisture protection, such as in production halls, outdoor areas, or machine construction facilities.

Compatibility and accessories – The gland is designed for wall thicknesses from 1.5 to 4.5 mm and adapts to the respective wall thickness due to its flexible construction. The sealing range of 7 to 13 mm allows use with cables or conduits within this diameter range.

Installation and mounting – Installation is done by inserting the gland into the pre-drilled opening in the wall. The elastic membranes automatically adapt and create a tight seal. No additional tools or mounting materials are required, as the gland creates the seal automatically due to its material flexibility. Installation is performed without additional sealing materials or adhesives.

Operational advantages – The double membrane sealing increases the reliability of the installation and extends the service life of the component. The IP66 protection rating provides a high level of protection against environmental influences, increasing the maintenance-free operation and safety of the system. The TPE material ensures high flexibility and resistance to mechanical stress, making the gland suitable for industrial applications.
