Ring terminal Ergom KOR 120/16 copper tin-plated (MPN E11KM-01020106900)

Ergom ring terminal KOR 120/16 is a tin-plated copper crimp lug designed for secure electrical connections where a ring-style termination is required. The terminal combines copper’s conductivity with a tin plating that improves corrosion resistance and solderability. It is intended for fixed connections to studs and terminal blocks in industrial, automotive, and panel wiring environments where a robust, low-resistance joint is needed.

Advantages

The tin-plated copper construction offers good electrical conductivity and enhanced protection against oxidation in humid or chemically active environments. Its ring shape ensures a reliable mechanical and electrical contact when fastened to a stud or screw terminal, reducing the risk of loosening under vibration. The crimp-style connection provides a consistent, low-resistance joint when installed with the correct crimping tool and technique.

Suitable for

• Industrial control panels and terminal blocks
• Automotive battery and grounding connections
• Power distribution and grounding straps
• Permanent crimped joints on medium to large cross-section cables

When it may not be suitable

This ring terminal is not intended for use on very small gauge wires below its rated cable cross-section or where a solderless push-fit or insulated quick-disconnect is required. It is designed for crimped or soldered terminations and requires a compatible crimping tool and appropriate cable preparation. For applications requiring high-temperature performance beyond typical tin-plated copper limits or for exposure to aggressive chemicals outside normal industrial conditions, alternative materials or protective measures should be considered.

Key specifications

• Material: Copper with tin plating
• Termination type: Ring lug (ring-style terminal)
• Recommended conductor cross-section: suited to medium to large cable sizes (refer to matching cable gauge)
• Mounting: Stud/screw connection compatibility
• Connection method: Crimp (recommended) or solder
• Typical uses: Power distribution, grounding, panel wiring

How to use

Strip the cable insulation to the correct length for the barrel, insert the conductor fully into the terminal barrel, and crimp using a suitable crimping tool sized for the terminal and conductor cross-section. Verify the mechanical strength and electrical continuity of the joint after crimping. If soldering is preferred, apply solder only after achieving a solid mechanical crimp to avoid cold joints; ensure proper ventilation and follow soldering safety practices. Mount the ring terminal on the stud or screw and tighten to the recommended torque for the terminal and stud size.

What to consider before purchase

• Confirm the terminal’s rated conductor cross-section matches the cable gauge you plan to use
• Ensure stud or screw diameter at the connection point fits the ring inner diameter
• Verify whether tin plating and copper material meet environmental and temperature requirements for your application
• Check that you have the appropriate crimping tool or soldering equipment for reliable installation

Usage recommendations

Use a dedicated crimping tool sized to the terminal for consistent, low-resistance connections. After crimping, perform a pull test and measure continuity. For corrosive or outdoor environments consider additional sealing or protective measures despite tin plating.
