Frequently Asked Questions
?What are ferrule terminals used for?
Ferrule terminals are crimped onto the end of a stripped stranded wire. They keep the wire strands together, preventing fraying and ensuring a highly secure, low-resistance connection in screw or spring clamp terminals.
?How do I choose the right size of a ferrule terminal?
You should select a ferrule terminal based on the wire gauge (AWG or mm²) you are using. The inner diameter of the metal barrel should match the outer diameter of the stripped conductor to guarantee a proper mechanical crimp.
?Are color codes for ferrule terminals standardized?
Yes, there are several color coding standards for insulated ferrules, the most common being the DIN 46228 standard, the French standard, and the German standard. These colors help identify the wire cross-section size easily.
?What is the difference between insulated and non-insulated ferrules?
Insulated ferrules feature a plastic collar at the end which provides extra insulation and guides the wire strands into the metal tube. Non-insulated ferrules do not have this collar and are typically used in tighter spaces where extra insulation is not required.
?Do I need a special tool to crimp ferrule terminals?
Yes, it is highly recommended to use a professional ferrule crimping tool. A dedicated crimper applies even, multi-sided pressure (square or hexagonal profile) to create a gas-tight connection, which cannot be reliably achieved with standard pliers.
?Can ferrule terminals be reused?
No, ferrule terminals are designed for single-use application. Once they are crimped onto a wire, the metal barrel is permanently deformed to secure the wire. If you need to make changes, the ferrule must be cut off and a new one applied.
