EM Group Tubular Ring Terminal 50mm² M12 Tinned Copper

The EM Group tubular ring terminal is a high-performance electrical component engineered for the secure termination of 50mm² conductors. Constructed from premium-grade tinned copper, this terminal provides superior electrical conductivity while offering robust protection against oxidation and environmental corrosion. Designed with an M12 mounting hole, it facilitates a stable and permanent connection point for heavy-duty electrical systems.

Advantages

The primary benefit of this tubular ring terminal lies in its high-quality tinned copper construction, which ensures minimal resistance and long-term reliability in demanding electrical environments. The tubular design allows for a precise crimping process, creating a solid mechanical and electrical bond with the conductor. Furthermore, the tin plating significantly enhances durability by preventing corrosion, making it an excellent choice for installations where long-term maintenance-free operation is required.

Suitable for

• Industrial electrical installations
• Power distribution panels
• Grounding and earthing systems
• Heavy-duty cable management
• Battery terminal connections

When it may not be suitable

This terminal is specifically designed for 50mm² conductors and an M12 bolt size. It is not suitable for cables with different cross-sections, as an improper fit will compromise the electrical connection. Additionally, it should not be used in applications requiring non-metallic or specialized alloy terminals.

Key specifications

• Conductor cross-section: 50mm²
• Mounting hole diameter: M12
• Material: Tinned copper
• Design: Tubular ring terminal

How to use

To install the terminal, first strip the insulation from the 50mm² conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade hydraulic or manual crimping tool compatible with 50mm² terminals to compress the barrel securely onto the wire. Once crimped, align the ring with the M12 mounting point and fasten it securely using a bolt and nut, ensuring the contact surface is clean and free of debris.

What to consider before purchase

• Verify the conductor cross-section matches the 50mm² specification.
• Ensure the M12 mounting hole is compatible with your existing hardware.
• Confirm that you have the correct crimping tool for this terminal size.

Usage recommendations

For optimal performance and safety, always ensure that the crimping tool is properly calibrated for 50mm² terminals. Avoid over-tightening the M12 bolt to prevent damage to the terminal or the mounting surface.
