Ring terminal Erko KOA M3 × 2.5 mm, copper, 100 pcs

Erko KOA ring terminal M3 × 2.5 mm is a copper crimp-style electrical connector designed for secure and low-resistance terminations. Supplied as a pack of 100 pieces, each ring terminal accepts conductor diameters up to 2.5 mm and fits an M3 screw or stud. The copper construction ensures good conductivity and corrosion resistance suitable for a wide range of electrical installations in control panels, machinery, and vehicles.

Advantages

These ring terminals combine a solid copper body with a precision-formed ring to provide consistent mechanical retention and reliable electrical contact. The crimp-style barrel enables a secure connection when properly crimped with a compatible tool, minimizing contact resistance. Supplied in a bulk pack of 100, they offer cost-effective quantity for projects and maintenance tasks while reducing handling time during assembly.

Suitable for

• Wire terminations on M3 screws or studs
• Control panels and industrial equipment wiring
• Automotive electrical connections and grounding points
• General household and commercial electrical installations

Key specifications

• Material: copper
• Ring inner diameter: suitable for M3 screw/stud
• Conductor size compatibility: up to 2.5 mm (solid or stranded)
• Connection type: crimp barrel
• Packaging: 100 pieces per pack

How to use

Strip the conductor insulation to the appropriate length for the crimp barrel, insert the conductor fully into the barrel, and crimp using a suitable insulated or non-insulated crimping tool rated for the conductor size. After crimping, position the ring over the M3 screw or stud and secure with the appropriate screw and washer as required. Verify that the mechanical fit is firm and that electrical continuity is intact using a multimeter if necessary.

Usage recommendations

Use the correct stripping length and a crimping tool matched to the terminal size to ensure a reliable connection. For exposed or outdoor applications, consider additional protective measures such as heat-shrink tubing or corrosion-inhibiting compounds to prolong service life.
