Crimp ring terminal Erko KOE_5-2,5/100, tinned, 1.5–2.5 mm², 100 pcs

Erko tinned ring crimp terminals KOE_5-2,5/100 are insulated electrical connectors designed to terminate and secure stranded conductors with a cross-section of 1.5–2.5 mm². Supplied in a pack of 100 pieces, these tinned ring terminals are intended for reliable connection to studs, bolts or screw terminals in automotive, industrial and domestic electrical installations. The tin plating improves corrosion resistance and ensures stable electrical contact over time.

Advantages

These ring crimp terminals combine a suitable conductor range (1.5–2.5 mm²) with a tinned surface finish to resist oxidation and maintain conductivity in humid or corrosive environments. The standardized ring size fits common M5 studs and screw terminals, while the crimp barrel is shaped for secure mechanical and electrical connection when used with an appropriate crimping tool. Supplied as a set of 100 pieces, the pack supports multiple wiring points and reduces the need for frequent reordering.

Suitable for

• Automotive electrical systems (battery and chassis connections)
• Industrial control panels and machinery wiring
• Household electrical appliances and junctions
• Renewable energy systems and panel connections

Key specifications

• Conductor cross-section: 1.5–2.5 mm²
• Terminal type: ring crimp terminal
• Contact finish: tinned (tin-plated)
• Suitable stud diameter: fits common M5-size studs and screw terminals
• Quantity per pack: 100 pieces

How to use

Strip the conductor insulation to the appropriate length, insert the bare conductor into the crimp barrel and use a suitable crimping tool to form a secure mechanical and electrical connection. Ensure the conductor strands are fully inserted and the crimp is firm; avoid loose or partial crimps. After crimping, place the ring terminal over the stud or screw and tighten the fastener to the manufacturer’s recommended torque for the terminal and conductor size.

Usage recommendations

Use a dedicated insulated or ratchet crimping tool sized for the 1.5–2.5 mm² range to achieve a consistent, reliable crimp. For outdoor or marine applications consider additional sealing or heat-shrink tubing to improve moisture protection despite the tin plating. Verify compatibility with the stud or screw size before installation and follow applicable electrical safety standards and torque specifications.
