Crimp Ring Terminal Erko KOE M10 × 2.5 mm, insulated, 100 pcs

Insulated crimp ring terminal Erko KOE M10 × 2.5 mm, supplied in a pack of 100 pieces, is designed for creating secure electrical connections to bolts and studs. The ring shape ensures mechanical retention when mounted on an M10 stud, while the insulated sleeve provides electrical isolation and protection for copper conductors with a 2.5 mm barrel diameter. This terminal is intended for low-voltage applications such as panel wiring, grounding and general electrical installations where a reliable bolted connection is required.

Advantages

The insulated construction reduces the risk of accidental short-circuits and improves safety during handling and maintenance. The ring contact form offers stable mechanical fastening and vibration resistance once tightened to a stud. Uniform crimpability of the 2.5 mm conductor barrel ensures consistent electrical contact and low contact resistance when proper crimping tools and techniques are used. Supplied in a bulk pack of 100 pieces, the terminals are convenient for repetitive installation tasks and small-to-medium projects.

Suitable for

• Panel wiring and terminal blocks
• Grounding and earthing connections
• Automotive low-voltage circuits and battery terminals
• Industrial control cabinets and junction points
• Repair and maintenance of electrical equipment

Key specifications

• Stud compatibility: M10
• Conductor barrel diameter: 2.5 mm
• Insulation: polymer sleeve for electrical isolation
• Contact shape: ring terminal
• Material: conductive metal for copper conductors (unplated or plated variants dependent on batch)
• Pack quantity: 100 pieces
• Application voltage range: suitable for low-voltage installations

How to use

Strip the conductor to the appropriate length for insertion into the 2.5 mm barrel, insert the bare conductor fully into the terminal barrel, and crimp using a suitable insulated terminal crimper sized for the barrel diameter. Place the ring over the M10 stud and secure with the appropriate nut and washer, ensuring proper torque per equipment specifications to maintain mechanical integrity and low contact resistance. Verify the connection visually and, if required, by a pull test or continuity measurement.

Recommendations for use

Use correctly sized crimping tools and follow the torque recommendations for M10 connections. Ensure the conductor is compatible with the 2.5 mm barrel and that insulation extends close to the crimp to maintain protection. Avoid exposing terminals to environments with excessive corrosion or temperatures beyond the specified limits of the insulation material.
