General
Colour	Yellow

The product is a cable marker from the brand Ses-Sterling, type Pliosnap+ PS-21 U yellow, specifically designed for cable identification in electrical installations. It enables clear identification of wires based on color and the printed letter U, with the color being yellow and the print in black. The markers are designed for cables with an outer diameter of 11.0 to 15.5 mm, suitable for cables with a cross-section of 35.0 mm². The material of the markers is POM (polyoxymethylene), a technical plastic known for its high strength, heat resistance, and abrasion resistance, ensuring long-term durability of the marking in industrial and electrical installations.

Applications

The marker is intended for use in electrical installations, particularly in systems where clear and permanent cable identification is required. The yellow color and the letter U serve as visual identification features, which may be defined in electrical schematics or installation specifications. The markers are suitable for cables with an outer diameter between 11.0 and 15.5 mm, making them applicable for medium to large cable cross-sections in power engineering applications. Typical use cases include industrial environments, during installation of distributors, in enclosures, or when wiring machinery.

Functions and Equipment in Detail

The markers are supplied as individual loose pieces and can be directly slipped onto the cable. The shape of the marker allows for secure fastening without additional tools. The black print U on a yellow background ensures good readability, even under low lighting conditions. The yellow color is often assigned to specific functions or phases in electrical installations, with exact assignments varying depending on project or standard requirements. The markers are made of POM, a thermoplastic material offering high mechanical strength and chemical resistance, enabling use in harsh environments.

Technology Explained Simply

The markers are designed as a snap system, meaning they can be slipped onto the cable without tools and are secured in place by a spring-loaded locking mechanism. The POM material provides high strength and resistance to wear, ensuring the marking remains intact even under mechanical stress or frequent handling. The yellow color and black letter U are directly applied to the marker’s surface, guaranteeing a durable and abrasion-resistant identification. The fit for cables with an outer diameter of 11.0 to 15.5 mm ensures the marker sits securely and does not slip.

Compatibility and Accessories

The markers are specifically designed for cables with an outer diameter of 11.0 to 15.5 mm and a cross-section of 35.0 mm², making them suitable for medium to large cables in power engineering applications. The yellow color and letter U are part of the identification system and can be used according to project requirements or standards. No specific accessories are included with this product; the markers are supplied as individual units.

Installation and Mounting

Installation requires no tools. The marker is simply slipped over the cable and secured by the spring-loaded locking mechanism at the end of the marker. The fit ensures the marker remains securely in place and does not slip off. Installation is quick and easy, even in confined spaces such as enclosures or distributors. The markers are intended for use in electrical installations, with exact positioning and quantity varying according to project requirements.

Individual markers are supplied in a packaging unit containing 50 pieces. The packaging is a bag designed to protect the material from contamination and damage. The packaging weight is 0.027 kg.

Operational Advantages

The use of POM as the material ensures high mechanical strength and long service life of the markers. The yellow color and black letter U enable clear and unambiguous identification, which remains intact even under frequent handling or in harsh environments. The tool-free installation speeds up the installation process and reduces labor effort. The fit for cables with an outer diameter of 11.0 to 15.5 mm ensures secure attachment, increasing the reliability of the marking. The markers are therefore suitable for use in industrial and electrical installations where durable and unambiguous cable identification is required.
