## Long description

Insulated copper ring terminal Erko KOE M12 x 2.5 mm, pack of 100. This product is a copper conductor ring terminal with an insulating sleeve, designed to be crimped onto appropriately sized stranded or solid wires to create a secure M12 ring connection for bolted terminals. The terminal provides a reliable electrical and mechanical connection with corrosion-resistant copper material and insulation that isolates the crimped joint. It is intended for use in electrical installations, control panels, automotive wiring, and industrial assemblies requiring dependable ring terminations.
Advantages
The insulated copper construction combines electrical conductivity with mechanical robustness for stable current transfer. The insulating sleeve protects the crimp area from accidental short circuits and provides strain relief to the conductor. The ring shape ensures a secure bolted connection and even contact pressure around the fastening point. Supplied in a pack of 100, these terminals simplify inventory management and reduce handling time for repetitive termination tasks.
Suitable for
 Electrical distribution blocks and control panels
 Automotive and vehicle electrical systems
 Industrial machinery and terminal strips
 Battery connections and grounding points
Key specifications
 Material: copper conductor with insulating sleeve
 Ring inner diameter: fits M12 bolts
 Conductor cross-section compatibility: 2.5 mm² equivalent AWG size
 Connection method: crimp termination
 Finish: corrosion-resistant copper surface
 Pack quantity: 100 pieces
How to use
Strip the conductor insulation to the appropriate length, insert the bare conductor fully into the terminal barrel and position the insulating sleeve against the wire insulation. Use a suitable crimping tool matched to 2.5 mm² terminals to apply a consistent, firm crimp so the conductor is mechanically secured and electrically continuous. After crimping, verify that the conductor cannot be pulled out and that the ring seats flat against the bolt or stud before tightening the fastener to the recommended torque for the application.
Usage recommendations
Choose the correct crimping die for 2.5 mm² terminals and inspect crimps visually and mechanically. For outdoor or corrosive environments, consider additional protection such as heat-shrink tubing or sealants over the insulation. Ensure bolt torque and washer usage follow equipment manufacturer guidelines to maintain a reliable connection.
