The Cimco crimp cable lugs, type 180056, are insulated ring cable lugs made of copper, designed for use in electrical installations with conductor cross-sections of 4 to 6 mm². They comply with the standard DIN 46237 and are designed for strain-relieved connections, with the insulation made of polyamide (PA), also known as nylon. The insulation sleeve is halogen-free and offers a temperature resistance from -60 °C to +105 °C, enabling use in various environmental conditions. The yellow insulation color identifies the cable lugs according to the standard for the corresponding cross-section group. The maximum operating voltage is 600 V. The cable lugs feature an Easy-Entry opening, which simplifies inserting the conductor and speeds up installation.

Applications
These cable lugs are suitable for use in electrical systems where a secure and strain-relieved connection between a conductor and a bolt is required. They are particularly suitable for industrial electrical installations, building electrical systems, and installations with increased requirements for insulation and mechanical stability. The PA insulation ensures high mechanical strength and chemical resistance, extending the service life of the connection.

Functions and Equipment in Detail
The cable lugs are made of copper of type Cu-ETP according to DIN EN 13600, with the surface galvanically tinned. This tinning improves corrosion resistance and contact quality. The ring shape allows secure fastening to a bolt with a diameter of 8 mm. The nominal size according to DIN is 8-6 mm, defining the fit for the specified conductor cross-section. The insulation is yellow and corresponds to the color coding for the cross-section group 4–6 mm². The dimensions of the cable lugs are as follows: D1 is 3.6 mm, D2 6.8 mm, D3 4.3 mm, A1 13 mm, B 8.4 mm, and L 25 mm. The weight is approximately 0.24 kg per 100 pieces.

Technology Explained Simply
The Easy-Entry opening is a mechanical design feature that facilitates inserting the conductor into the cable lug without requiring additional tools or special installation force. The polyamide (PA) insulation is heat- and chemical-resistant, enabling use in industrial environments with increased loads. The galvanic tinning of the copper surface prevents oxidation and ensures a stable electrical contact. The temperature resistance from -60 °C to +105 °C makes the cable lugs suitable for applications in climatically diverse regions, including outdoor areas, provided environmental conditions remain within the specified limits.

The maximum operating voltage of 600 V is sufficient for many industrial and commercial applications, particularly in low-voltage systems. The halogen-free insulation means lower smoke and gas emission in case of fire, thereby increasing safety.

Compatibility and Accessories
The cable lugs are designed for bolts with a diameter of 8 mm and thus fit standard screw connections in electrical installations. They are manufactured according to DIN 46237 and meet the requirements for insulated crimp cable lugs. Use in combination with other components of the same standard is possible, provided mechanical and electrical requirements are compatible. The cable lugs are UL-listed, confirming their approval for use in certain markets, particularly in North America.

Installation and Mounting
Installation is performed by inserting the conductor into the Easy-Entry opening and then crimping with a suitable tool, such as a cable lug crimping tool. The connection is then fastened to a bolt with an 8 mm diameter. The strain-relieved design ensures that mechanical stress from pulling forces is not transferred to the conductor, but to the bolt and screw connection. The insulation remains intact, ensuring electrical safety.

Operational Advantages
The cable lugs provide a reliable electrical connection with high mechanical stability. The galvanic tinning extends service life and reduces maintenance. The halogen-free insulation increases fire safety. The Easy-Entry function speeds up installation and reduces error susceptibility. Compliance with DIN 46237 and UL listing enables use in various markets and application areas.
