Insulated Ferrules

Insulated ferrules

Ferrules are cylindrically-shaped copper tubes crimped to the ends of stranded wire to create a secure, reliable connection. They are primarily used to consolidate wire strands for the purpose of eliminating wire fraying and resulting shorts, as well as for allowing easier insertion and removal of wires from terminal blocks or other termination devices, especially in areas of confined space or when using small wires. Ferrules also create a reliable connection by ensuring that each wire strand conducts current. Two-wire ferrules allow two individual stranded conductors to be connected to the same termination, which can be especially useful in jumpering applications.

Our ferrules are made from electrolytically tin-plated copper (99.9%) with either standard or DIN color polypropolyne insulation rated to 105°C. When selecting ferrules for use with DINnectors, choose the longest length version where available. Our industrial quality ferrule crimping tools crimp insulated and uninsulated single or two wire ferrules. Ferrules are available in:
