Gustav Klauke KLAU 126R Crimp Butt Connector 50 mm², Galvanically Tinned, DIN 46267

When high-current copper connections must hold up in demanding environments, the Gustav Klauke KLAU 126R crimp butt connector delivers the reliability you expect from a brand trusted by professionals. This 50 mm² press connector is galvanically tinned for superior corrosion resistance, ensuring a stable, long-lasting joint even in humid or industrial settings. Its compact, uninsulated design is engineered for hexagonal crimping, providing a secure, low-resistance connection for two copper conductors.

Highlights

• Conductor cross-section: 50 mm² – ideal for medium to heavy-duty power applications
• Galvanically tinned surface – excellent corrosion protection and low contact resistance
• Manufactured from high-purity electrolytic copper (E-Cu, >99.9% Cu) for optimal conductivity
• Complies with DIN 46267 – ensures dimensional and performance consistency
• Hexagonal crimp type – creates a strong, vibration-resistant mechanical joint
• Wide operating temperature range: -50°C to +150°C
• Rated for up to 1000 V – suitable for many industrial and commercial installations

In daily use

Whether you are terminating cables in a control cabinet, connecting busbars, or repairing heavy machinery wiring, the KLAU 126R simplifies the task. Its precise inner diameter (approx. 10.2 mm) and outer dimensions (approx. 13.5 mm) match standard crimping dies, allowing for consistent, repeatable results. The tinned surface also simplifies soldering if required, though crimping alone provides a durable, maintenance-free joint. Because it is uninsulated, always use appropriate heat-shrink tubing or insulation where needed.
