## Summary description

The EM Group tubular ring terminal is designed for reliable electrical connections of 16mm² conductors. Featuring an M6 stud hole, this terminal is manufactured from high-quality unplated copper, ensuring excellent conductivity and durability. It is ideal for professional electrical installations, power distribution, and grounding applications where a secure, permanent connection is required.

## Long description

The EM Group tubular ring terminal is a high-quality electrical component engineered for the secure termination of 16mm² conductors. Designed with an M6 stud hole, this terminal provides a stable and reliable connection point for various electrical systems. Constructed from unplated copper, it offers superior electrical conductivity and mechanical strength, making it a dependable choice for demanding industrial and commercial applications where consistent performance is essential.
Advantages
The primary benefit of this tubular ring terminal is its robust construction from high-grade copper, which ensures minimal resistance and optimal current flow. The tubular design allows for a deep and secure crimp, providing excellent pull-out resistance and long-term durability. Its unplated finish is specifically chosen for applications where direct copper-to-copper contact is preferred or required, ensuring that the connection remains stable under varying thermal conditions.
Suitable for
Electrical power distribution panels
Grounding and earthing systems
Industrial machinery wiring
Battery cable terminations
Professional electrical installations
When it may not be suitable
This terminal is not suitable for environments with high humidity or corrosive atmospheres, as the unplated copper surface is prone to oxidation over time. It should also not be used with conductors that do not match the 16mm² specification, as an improper fit will compromise the integrity of the electrical connection.
Key specifications
Conductor cross-section: 16mm²
Stud hole diameter: M6
Material: Unplated copper
Terminal type: Tubular ring
How to use
To install the terminal, first strip the insulation from the end of the 16mm² conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade crimping tool specifically calibrated for tubular copper terminals to compress the barrel onto the wire. Once crimped, place the ring end over the M6 stud and secure it firmly with a corresponding nut and washer to ensure a tight, low-resistance connection.
What to consider before purchase
Verify that the conductor size is exactly 16mm²
Ensure the M6 stud size matches your mounting hardware
Check if the application environment requires plated terminals for corrosion resistance
Confirm you have access to the correct crimping tool for tubular terminals
Usage recommendations
Always ensure that the crimping tool is fully closed during the process to achieve a gas-tight connection. Periodically inspect the connection for signs of oxidation or loosening, especially in high-vibration environments.
