RS PRO Insulated Crimp Bootlace Ferrule, 12mm Pin Length, 4.2mm Pin Diameter, 2 x 4mm² Wire Size, Grey

RS Insulated Twin Entry Bootlace Ferrules

From RS Pro a range of high-quality colour coded bootlace ferrules (also known as cord end terminals) with a twin entry for providing a clean end termination to multi-stranded wires. These reliable wire ferrules ensure that you have a positive connection when connecting wires to terminal blocks and captive terminals.

What Is a Bootlace Ferrule?
A bootlace ferrule is a metal tube or ferrule with a moulded colour coded insulating collar made from nylon. The ferrule is slipped over the end of a multi-stranded wire, crimped and then inserted into a screw or spring clamp connection.

Where is a Bootlace Ferrule Used?
When the end of a multi-stranded wire is stripped and placed directly under a screw terminal the strands of the wire will naturally fan out under the pressure of the screw. Some strands will go astray. This reduces the quality of the electrical connection and can also result in electrical shorts. When a bootlace ferrule is used, the insulated funnel with it's flared design captures all the strands. These strands are then crimped together in the ferrule tube. The crimped ferrule is then inserted into the terminal to create an electrical connection

Features and Benefits
• Insulation collar accepts two multi-stranded wires
• Excellent electrical connection
• Reduces short circuits
• DIN colour coded collar for easy ferrule size identification
• Nylon insulated collar for reduced leakage, creepage and gas intrusion
• Tin plated copper tube for excellent conductivity
• Crimped terminal can be repeatedly inserted and removed without degrading end of the wire

Applications
Bootlace ferrules are used on multi-stranded wires that are being inserted into screw terminals and terminal blocks. Applications include consumer units, circuit breakers, electrical control panels and any equipment where there is a requirement for a multi-stranded wire connection.

Questions and Answers

How to Crimp a Bootlace Ferrule
Select the correct size bootlace ferrule and strip the end of the wire. Cut the wires to the same length as terminal and twist the strands together. Slip the bootlace ferrule (insulated collar first) onto the ends of the wire until the wire strands are flush with the end of the tube. Using a ratchet crimping tool, insert the metal tube of the ferrule into the appropriate crimping section (indicated by sizes marked on the tool). Squeeze the tool handles together until the ratchet releases. A ratchet crimping tool is preferable as the handles will remain locked until a full crimp cycle is completed preventing partial crimps. The crimped wire end is now ready to be inserted into connecting terminal
