Klauke 93R4 Ring Terminal - Tubular - Tin-Plated Copper - 2.5 mm² - M4 Bolt Hole

The Klauke 93R4 is a high-quality, uninsulated ring terminal designed for reliable and secure electrical connections. Manufactured from electrolytic copper with a tin-plated surface, this tubular ring terminal ensures excellent conductivity and corrosion resistance. It is suitable for cable cross-sections of 2.5 mm² and features a bolt hole diameter of 4.3 mm (M4). The terminal is crimped using a hexagonal crimping method, providing a strong and durable connection. Compliant with DIN 46235 and RoHS, it operates in a wide temperature range from -55°C to +150°C.

Advantages

Tin-plated copper construction offers superior corrosion resistance and long-lasting performance. The tubular barrel design allows for easy insertion of stranded or solid conductors. Hexagonal crimping ensures a gas-tight connection, reducing resistance and preventing loosening. Suitable for a wide range of industrial and electrical applications.
