Manufacturer	Weidmüller

The Weidmüller WKM 8/30 is a cable marker made of polypropylene, specifically developed for the identification of electrical conductors and cables in systems and devices. It serves for clear identification, organization, and traceability of wiring, minimizing error sources during maintenance, installation, or revision. With dimensions of 30 mm length and 8 mm width, it is suitable for clear labeling, while the material choice of polypropylene (PP) ensures high resistance to mechanical stress and environmental influences. The markers are designed for use in industrial and technical systems where durable and legible labeling is required.

Applications

The WKM 8/30 is used in electrical and automation technology, particularly in the installation of control and distribution systems. It is suitable for labeling cables, conductors, connectors, and other electrical components in machines, systems, enclosures, and distribution boxes. Use in industrial environments requires robust labeling that remains stable even under high temperatures, humidity, or mechanical stress. The polypropylene material provides good resistance to moisture and minor chemical influences.

Functions and Equipment in Detail

The marker is designed as a single unit and is applied directly onto the conductor or cable. It is not self-adhesive, but is secured via a special clamp or insert function, with the exact mounting method depending on the used marker holder or marking device. The dimensions 30 mm × 8 mm provide sufficient space for clear labeling, which may include numbers, functions, or assignments. The material thickness and shape ensure stable attachment to the cable, preventing shifting or wear.

Technology Explained Simply

The material polypropylene (PP) is a thermoplastic polymer known for its high mechanical strength, resistance to moisture, and low density. It is non-flammable and exhibits good aging resistance, making it suitable for use in industrial systems. The dimensions 30 mm × 8 mm are standardized and fit common marking devices and holders used in electrical installations. The markers are not self-adhesive but are secured via mechanical holding devices, enabling repeatable and secure installation.

Compatibility and Accessories

The WKM 8/30 is compatible with various marking devices and systems, particularly with marking devices from the Weidmüller product line. Suitable accessories include, for example, insert markers such as the ELS 6/30 MM WS (white) or ELS 6/30 MM GE (yellow), available in similar dimensions (30x6 mm). MultiCard systems such as the ELS 6/30 MC NE WS or ESO 7 P DIN A4 WS are also available and enable structured labeling.

Installation and Mounting

Installation is performed via mechanical fastening, for example using a marking device that applies the marker onto the cable. The exact mounting method depends on the used holder or marking device. It is important that the marker sits firmly and without shifting on the cable to ensure durable labeling. The material strength of polypropylene ensures that the marker does not tear or deform under mechanical stress.

Advantages in Operation

The use of the WKM 8/30 improves clarity and maintainability of electrical systems. Clear labeling reduces errors during maintenance and facilitates identification of conductors. Material strength and standardized dimensions ensure long service life and compatibility with common marking systems. The non-self-adhesive design enables flexible installation and reusability if labeling needs to be changed or removed.
