Choosing the Right Terminal Crimps

Selecting the correct terminal crimp is critical for safe, durable electrical connections. This guide explains crimp types, colour coding, sizing, and best practice.

1. What Are Terminal Crimps?

Terminal crimps provide a secure mechanical and electrical connection between a conductor and a termination point without soldering.

2. Colour Coding & Cable Size

Red: 0.5 – 1.5 mm²
Blue: 1.5 – 2.5 mm²
Yellow: 4 – 6 mm²

3. Types of Terminal Crimps

Ring terminals
Fork / spade terminals
Blade terminals
Butt connectors
Pin terminals

4. Matching Crimps to Tools

Use crimp tools designed for the terminal type and size. Incorrect tooling can result in weak connections or conductor damage.

5. Standards & Quality Considerations

High-quality terminals manufactured to recognised standards ensure consistent crimp performance, long service life, and electrical reliability.
