Insulated Bootlace Ferrules (0.5mm – 70mm) – Complete Guide


Insulated bootlace ferrules (also called cord end terminals) are crimpable connectors used to secure stranded wires in screw terminals, preventing fraying and improving conductivity. They are essential in industrial control panels, DIN rail terminals, and electrical installations where reliability is critical.






???? Key Features


✅ Material:





  • Ferrule Barrel: Copper (tin-plated for corrosion resistance).




  • Insulation: PVC or nylon (color-coded by size).
    ✅ Size Range:




  • 0.5mm² – 70mm² (AWG 22 – 2/0).




  • Common sizes: 0.5mm² (24 AWG), 1.5mm² (16 AWG), 6mm² (10 AWG), 35mm² (2 AWG).
    ✅ Insulation Types:




  • Transparent (allows wire inspection).




  • Color-coded (for easy identification).
    ✅ Standards:




  • UL, VDE, RoHS compliant (check manufacturer specs).







???? Why Use Bootlace Ferrules?


✔ Prevents Strand Breakage – Stops wires from fraying in screw terminals.
✔ Better Conductivity – Ensures full contact in terminal blocks.
✔ Vibration-Resistant – More secure than bare stranded wire.
✔ Reusable – Can be reinserted into terminals without damage (unlike twisted strands).






???? How to Crimp Bootlace Ferrules?




  1. Strip Wire (~8–10mm).




  2. Twist Strands (lightly to keep them together).




  3. Insert into Ferrule (ensure full seating).




  4. Crimp with Bootlace Ferrule Tool (special hexagonal crimper).




  5. Tug Test (confirm secure crimp).




⚠ Warning:





  • Never use standard crimpers (requires hexagonal crimp for proper compression).




  • Match ferrule size to wire gauge (too loose = poor contact, too tight = damage).

???? FAQ


❓ Can I use ferrules on solid wire?
→ No, only stranded (solid wire doesn’t need them).


❓ Are non-insulated ferrules available?
→ Yes, but insulated is recommended for most applications.


❓ Can I reuse crimped ferrules?
→ No, but the terminal block connection is reusable.
