EM Group Tubular Ring Terminal 25mm² M12 Tinned Copper

The EM Group tubular ring terminal is a high-performance electrical component engineered for the secure termination of 25mm² conductors. Constructed from premium-grade tinned copper, this terminal provides superior electrical conductivity and long-term protection against oxidation and environmental corrosion. Its robust tubular design ensures a tight, reliable crimp connection, while the M12 mounting hole allows for stable attachment to busbars, studs, or terminal blocks in demanding electrical systems.

Advantages

The primary benefit of this terminal lies in its high-quality tinned copper construction, which significantly enhances durability and prevents the degradation of electrical contact over time. The tubular design facilitates an efficient and uniform crimping process, ensuring that the conductor remains firmly in place under mechanical stress or vibration. Furthermore, the precise M12 sizing offers compatibility with standard industrial hardware, making it an essential component for maintaining consistent power distribution and minimizing resistance in critical electrical circuits.

Suitable for

• Industrial power distribution panels
• Electrical switchgear and control cabinets
• Battery cable terminations
• Grounding and earthing connections
• Heavy-duty electrical machinery

This terminal may not be suitable for applications involving conductors with a cross-section significantly different from 25mm², as an improper fit can lead to high contact resistance or mechanical failure. It is also not intended for use in environments where the specific chemical compatibility of tinned copper is compromised by highly aggressive substances.

Key specifications

• Conductor cross-section: 25mm²
• Mounting hole diameter: M12
• Material: Tinned copper
• Design: Tubular ring terminal

To use this terminal, first strip the insulation from the end of the 25mm² conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Using a professional-grade hydraulic or manual crimping tool designed for tubular terminals, apply sufficient pressure to create a permanent, gas-tight connection. Ensure the terminal is clean and free of debris before fastening it to the M12 stud using a compatible nut and washer, tightening to the manufacturer's specified torque.

What to consider before purchase

• Verify that the conductor cross-section is exactly 25mm²
• Ensure the M12 stud size matches your existing hardware
• Confirm that the crimping tool available is compatible with tubular terminals
• Check the environmental conditions to ensure tinned copper is appropriate for the application

For optimal performance and safety, always use a calibrated crimping tool and ensure the connection point is clean and free of oxidation before installation. Periodically inspect the connection for signs of overheating or mechanical loosening.
