Insulated ring terminal BM S.P.A 2.5 mm² blue, tin-plated copper, pack of 10 (MPN BEBM00231S)

Insulated ring terminal for electrical connections designed for 2.5 mm² conductor cross-section. The blue insulation identifies the terminal size and provides electrical isolation, while the ring contact is made from tin-plated copper to offer corrosion resistance and consistent conductivity. Supplied as a pack of 10, these terminals are intended for crimping to form reliable screw or stud terminations used in automotive, industrial and household wiring applications.

Advantages

The tin-plated copper ring contact ensures low contact resistance and enhanced corrosion protection compared with bare copper. Colour-coded insulation simplifies wire identification and selection for 2.5 mm² conductors. The insulated barrel provides mechanical support and electrical isolation at the crimp point, reducing the risk of short circuits. Supplied in a pack of ten, the product offers a convenient quantity for repair, maintenance and small installation jobs.

Suitable for

• Crimp terminations on 2.5 mm² stranded or solid copper conductors
• Securing connections to screws, bolts or studs in automotive electrical systems
• Industrial control panels and terminal blocks requiring ring-type terminations
• Household wiring repairs and small appliance connections

Key specifications

• Conductor cross-section compatibility: 2.5 mm²
• Insulation colour: blue (size identification and electrical isolation)
• Contact material: tin-plated copper for improved corrosion resistance
• Terminal style: ring (for screw or stud fastening)
• Connection method: crimp barrel with insulated sleeve
• Pack quantity: 10 terminals

How to use

Strip the conductor to the appropriate length so that exposed copper fits fully into the crimp barrel without leaving stray strands. Insert the stripped conductor into the barrel until the insulation meets the sleeve. Use a suitable insulated crimping tool rated for 2.5 mm² terminals and apply a firm, even crimp to compress the barrel around the conductor. After crimping, verify mechanical retention by applying a gentle pull and visually inspect the crimp for a uniform deformation. Mount the ring terminal onto the screw or stud and tighten the fastener to the appropriate torque for the application, observing any equipment-specific recommendations.

Usage recommendations

For reliable long-term connections, use a quality crimping tool sized for insulated ring terminals and avoid using pliers-only crimps. Ensure the mating screw or stud and the terminal contact surface are clean and free of paint or oxidation. Where increased environmental protection is required, consider additional sealing or use of heat-shrink insulated variants compatible with 2.5 mm² terminals.
