The Klauke tube terminal lug type 1R5MS is a terminal lug for use in enclosure construction, specifically designed for multi-strand round conductors, for example according to VDE 0295 class 2, as well as for round-compressed multi-strand sector conductors. It is used for secure and durable connection of conductors with a cross-section of 6 mm² to M5 plug connection points. The terminal lug features optimal crimpability, achieved through annealed material, ensuring a stable and corrosion-resistant connection. The galvanic tin plating protects the terminal lug against corrosion and ensures good electrical conductivity. The material consists of E-Cu, in accordance with standard EN 13600, which secures the electrical and mechanical properties of the terminal lug.

Tube terminal lug

The terminal lug features a flat contact surface and precise end finishing, enabling easy and secure cable insertion. The shape of the tube terminal lug ensures even distribution of crimping force and prevents conductor displacement within the lug. The article identification is directly marked on the terminal lug, facilitating identification and sorting during operation. Processing is done by crimping, where the specific geometry of the lug enables a reliable connection even under dynamic loads.

Applications

The terminal lug is primarily intended for use in enclosure construction, where high mechanical stability and electrical reliability are required. It is suitable for applications in industrial electrotechnics, for connecting cables to plug connections, for example on switches, relays or other components. Its use is particularly suitable for installations subject to high vibration loads, as the terminal lug is vibration-tested according to DIN EN 61373 class 1 B. This guarantees that it will not loosen or degrade the electrical connection under dynamic loads.

Functions and equipment in detail

The galvanic tin plating of the terminal lug protects the copper material against oxidation and corrosion, increasing its service life and electrical conductivity over time. The flat contact surface ensures secure and surface-wide contact with the connection point, ensuring even load distribution and low risk of contact overheating. The precise end finishing facilitates cable insertion and prevents conductor damage during installation. The article identification on the terminal lug enables quick identification, especially in complex control systems.

Technology explained clearly

The terminal lug is processed by crimping, where mechanical force presses the conductor into the lug to create a secure connection. The annealed material allows plastic deformation without cracking, which is crucial for a durable connection. The standard DIN EN 61373 class 1 B refers to vibration resistance, ensuring that the terminal lug maintains its function even under mechanical vibration loads. The tin plating is a protective layer that shields the copper from environmental influences such as moisture and humidity, without impairing electrical properties.

The use of E-Cu (electrolytic copper) in accordance with EN 13600 ensures high electrical conductivity and mechanical strength. The material is standard for use in electrical installations, as it provides the required properties for reliability and performance.

Compatibility and accessories

The terminal lug is designed for multi-strand round conductors according to VDE 0295 class 2 as well as for round-compressed multi-strand sector conductors. The cross-section is 6 mm², and the lug is designed for M5 plug connections. Use is in combination with crimping tools specifically designed for the respective terminal lug type.

Installation and mounting

Mounting is done by crimping with an appropriate tool that meets the specific requirements of the terminal lug. The precise end finishing and flat contact surface facilitate correct positioning of the cable and lug. Crimping must be performed so that the conductor is fully seated in the lug and a secure connection is established. The article identification aids in control and documentation of the components used.

Advantages in operation

The terminal lug offers high mechanical stability and electrical reliability, especially in applications with vibration loads. The galvanic tin plating increases corrosion resistance and extends service life. The easy cable insertion and clear identification simplify installation and maintenance. The use of E-Cu in accordance with EN 13600 ensures the required electrical and mechanical properties for use in industrial installations. The vibration-tested design according to DIN EN 61373 class 1 B ensures functionality under dynamic loads.
