Aluminum Ring Terminal Ergom 2KAM 120/12 (E12KA-01050103100) — ring cable lug 12 mm, 120 A

Aluminum ring terminal Ergom 2KAM 120/12 is a crimp-style ring cable lug designed to provide a reliable mechanical and electrical connection for conductors up to the specified current rating. Constructed from aluminum, this ring terminal features a circular eye for secure bolted attachment to studs or posts and is intended for applications that require a lightweight, corrosion-resistant terminal capable of handling up to 120 A on a 12 mm stud.

Advantages

The aluminum construction delivers good conductivity combined with low weight and improved resistance to environmental corrosion compared to bare copper in some installations. The crimp-type barrel ensures a solid mechanical bond with appropriate crimping tools, reducing contact resistance and improving long-term reliability. The ring (eye) design provides a secure bolted connection that resists vibration-induced loosening and allows straightforward installation in tight or crowded terminal layouts.

Suitable for

• Battery terminal connections in vehicles and stationary power systems
• Electrical wiring and distribution blocks in industrial equipment
• Marine and outdoor installations where corrosion resistance and light weight are important
• Control panels and junction boxes requiring bolted cable terminations

Key specifications

• Material: Aluminum
• Connection type: Ring (eye) terminal for bolted attachment
• Stud size compatibility: 12 mm
• Current rating: 120 A
• Termination method: Crimp barrel for conductor insertion and crimping

How to use

Select a conductor with an appropriate cross-sectional area for the 120 A rating, strip the insulation to the recommended length for the terminal barrel, insert the conductor fully into the crimp barrel, and apply a suitable crimping tool designed for aluminum terminals to form a secure crimp. Position the ring over the target stud or post, fit any required washer or insulating spacer, and tighten the fastening hardware to the manufacturer's torque specification to ensure a reliable bolted contact. Confirm the connection is mechanically stable and electrically continuous before applying full system power.

Usage recommendations

For optimal performance and safety, use a crimping tool specified for aluminum terminals, apply anti-oxidation compound where appropriate in dissimilar-metal connections, and ensure all fasteners are tightened to recommended torque values. Inspect connections periodically for signs of corrosion or loosening, especially in high-vibration or outdoor environments.
