The product is a marking ring from the PLIO-M-MARKERS product series, type M-65 C, manufactured by Ses-Sterling. Marking rings are used for the clear identification of cables in the field of electrical and IT installations. They are finished in white with a black print of the marking "C", ensuring high visibility and readability even under low lighting conditions. The rings are made of soft PVC, providing high flexibility and easy handling, especially when mounting on cables with different diameters.

Marking rings are specifically designed for use in cable installations, where durable and robust labeling is required. The rings are supplied in strip form and pre-cut, allowing them to be quickly and easily slid onto the cable without additional tools. The use of soft PVC ensures good adhesion to the cable surface and prevents the marking from shifting or falling off during operation.

Applications include primarily the marking of power and low-voltage cables in industrial, commercial, and building installations. The rings are designed for cables with an outer diameter of 4.2 to 6.6 mm, corresponding to a cable cross-section of 10 to 16 mm². These dimensions cover a typical range for medium to large cables commonly used in electrical installations. The marking "C" allows for clear assignment within a cable system, for example, to distinguish between phases, functions, or circuit branches.

Functions and equipment in detail include the pre-cut strip form, which enables quick and precise installation without additional tools. The choice of soft PVC material ensures high flexibility and shape stability, allowing the rings to conform to the cable surface while maintaining their shape. The white color with black print provides high contrast, ensuring readability even after prolonged use and under various lighting conditions.

Technology explained simply shows that the rings do not perform any electrical functions, but work purely mechanically and visually. The soft PVC structure is non-conductive and does not provide electrical insulation — its purpose is exclusively visual marking. The pre-cut form reduces installation time and minimizes errors in labeling, as each piece already has the correct length for the intended cable diameter.

Compatibility and accessories refers to use with cables within the specified diameter and cross-section range. The rings are not suitable for cables outside the range of 4.2 to 6.6 mm outer diameter, as they either cannot be slid on or will not sit securely.

Installation and mounting is done by simply sliding the ring onto the cable. The pre-cut strip form allows for quick and secure installation without additional tools. The flexibility of the soft PVC material ensures that the ring elastically adapts to the cable and provides a secure fit. No special mounting instructions are required, as handling is intuitive.

Operational advantages include easy and quick application, high readability of the marking, and the durability of the material. The rings retain their shape and color over long periods, even under normal indoor environmental conditions. The clear marking "C" enables efficient system overview and simplifies maintenance and repair work, as cables can be quickly identified.

The packaging contains 100 pieces, which is sufficient for larger installations or series mounting. The weight of a single ring is 0.23 g, which does not affect handling or storage. Use is limited to indoor installations, where the material resistance of soft PVC is sufficient.
