General
Material	Polypropylene
Product type	cable marker
Application	Identification of conductors and cables

The Weidmüller WKM 18/43 is a cable marker made of polypropylene, used for clear identification, organisation and traceability of electrical conductors and cables in systems and devices. It serves as an identification component in the field of installation technology and enables clear identification of connections, particularly in complex switchgear, machines or industrial controls. The dimensions of 43 mm length and 18 mm width provide sufficient space for legible labelling, which, due to the polypropylene material, is resistant to mechanical stress and environmental influences.

Applications

The marker is intended for use in electrical and electronic systems where clear and durable identification of cables and conductors is required. It is used in industrial electrical installation, automation technology, as well as in building and machine control. Due to the polypropylene material, it is suitable for use in environments with increased mechanical stress or in areas with lower humidity and temperature risks. The dimensions of 43x18 mm adapt to standard cable diameters and types, enabling universal use in various installation scenarios.

Functions and equipment in detail

The WKM 18/43 is a self-adhesive marker that is applied directly to cables, conductors or other electrical components. The polypropylene surface is designed for good adhesion of the adhesive and simultaneously offers high resistance to mechanical influences. The material choice ensures a long service life of the identification, even under normal operating conditions. The markers are manufactured in a standard size of 43 mm length and 18 mm width, enabling clear labelling without appearing too small or too large.

Technology explained simply

Polypropylene is a thermoplastic polymer known for its high mechanical strength, resistance to moisture and chemical resistance. These properties make the marker particularly suitable for use in industrial environments where it may be exposed to mechanical stresses such as friction or pressure. The self-adhesive backing allows for easy and quick installation without additional tools. The dimensions of 43x18 mm are standardised and compatible with common labelling devices and marking systems used in electrical and automation technology.

Compatibility and accessories

The marker is compatible with various marking devices and labelling systems, particularly with the connection markers of the ESO 5 DIN A4 series, available in variants GE (grey) and WS (white). Additionally, suitable insert markers such as the ELS 16/40 MM WS or ELS 16/40 MC NE WS are available, which, in combination with the WKM 18/43, enable structured identification. These accessories support the creation of uniform labelling systems required in industrial electrical installation.

Installation and mounting

Installation is performed by simply peeling off the protective film and sticking the marker onto the desired cable or conductor. The self-adhesive backing ensures secure attachment without requiring additional adhesives or tools. The dimensions of 43x18 mm allow for precise placement, while the labelling remains clear and legible. The material strength of polypropylene ensures that the identification does not slip or become damaged even under mechanical stress.

Advantages in operation

The use of the WKM 18/43 improves the clarity and maintainability of electrical systems. Clear identification reduces errors during installation, maintenance or repair and enables quick identification of lines. The material durability ensures a long service life of the marking, thereby reducing the need to frequently replace markers. Compatibility with common marking devices and accessories facilitates integration into existing identification systems.
