Klauke 227R Aluminium Press Connector 70mm² rm/sm Bare

The Klauke 227R is a high-quality aluminium press connector designed for reliable joining of aluminium conductors. Suitable for round multi-wire (rm) and sector multi-wire (sm) conductors with a cross-section of 70 mm², this uninsulated tubular connector ensures excellent electrical conductivity and corrosion resistance. Manufactured by Klauke, a trusted brand in professional crimping technology, the 227R is ideal for power distribution and industrial applications.

Advantages

High electrical conductivity and corrosion resistance ensure long-lasting performance. The bare aluminium surface provides optimal contact without additional plating. Designed for two crimps, the connector offers secure and consistent connections when used with the appropriate crimp tool. Operating temperature range from -40°C to +120°C makes it suitable for harsh environments.
