The DA 250/470/40 cable gland from Ses-Sterling is a protective component made of polychloroprene rubber, specifically designed for the safe and durable routing of cables and lines through components such as wall penetrations, enclosures or machine constructions. The product is available in black and serves as a rubber gland for mechanical and electrical insulation, as well as protection against mechanical stresses such as friction or pressure. The gland is used in electrical installation, machine construction and industrial plant assembly, where reliable cable routing is required.

Applications

The DA 250/470/40 is designed for use in industrial and technical installations where cables must be routed through rigid components. Typical applications include routing control lines, data cables or power supply lines through metal plates, enclosure walls or machine cabinets. The gland protects the cable sheathing from mechanical damage such as cracking or abrasion, and prevents dust, moisture or foreign objects from entering the installation. Due to the polychloroprene rubber used, it is suitable for a wide range of environmental conditions, including light chemical exposure.

Functions and Features in Detail

The gland provides a cable routing function, enabling cables to be safely routed through an opening without additional fastening elements. The shape ensures a tight fit to the opening, providing secure holding of the line and minimal movement. The protective function is achieved through the elastic structure of the material, which adapts to cable diameters and provides a tight seal against environmental media. The black color is standard and meets typical requirements in industrial electrical installation.

Technical Explanation

The gland is made of polychloroprene rubber, an elastic, durable material known for its high mechanical strength, resistance to weathering and flexibility at various temperatures. The material allows for durable, low-friction cable routing without damaging the cables. The designation DA 250/470/40 refers to the technical dimensions: the gland is designed for an opening size of 250 mm to 470 mm and cable diameter adaptation up to 40 mm. These specifications define the application limits and enable precise selection for the respective use.

Compatibility and Accessories

The DA 250/470/40 is compatible with cables and lines with a diameter up to 40 mm. The gland is supplied in a pack of 50 pieces, suitable for larger installation projects or series applications. There are no specific accessories recommended by the manufacturer as supplements; the gland is used as a single component. Installation requires no additional fastening elements, as the elastic shape provides the holding force.

Installation and Mounting

Mounting is done by simply inserting the gland into the designated opening. The elastic structure ensures the gland adapts to the shape of the opening and creates a secure, tight connection. Cables are then routed through the gland, with the elastic fit preventing shifting or displacement of the lines. Installation requires no tools or additional mounting aids. The gland is designed for single-use mounting and is not reusable.

Operational Advantages

The DA 250/470/40 provides a reliable, durable and maintenance-free solution for cable routing. The mechanical protection function extends cable life by protecting them from friction and mechanical pressure. The sealing properties prevent dust, moisture or other environmental media from entering, increasing the reliability of the electrical connection. Simple installation and high fit accuracy reduce installation time and minimize error sources. The gland is designed for industrial environments where high demands on safety and longevity apply.
