Insulated Cord End Terminals – Single & Twin Wire Ferrules

Clean Wire Termination. Secure Crimping. Precision-Molded Insulation Collars.

Insulated cord end terminals, also known as wire end ferrules or bootlace ferrules, are designed to protect stranded copper conductors and create clean, consistent wire ends for terminal block connections.

Available in single-wire and twin-wire designs, with vinyl (PVC) and nylon insulation options for different electrical installation requirements.

Reliable Termination for Stranded Wires

The tin-plated copper sleeve holds individual wire strands together after crimping, helping prevent fraying, stray strands and wire damage during terminal insertion.

The color-coded insulation collar guides the wire into the sleeve and helps identify the conductor size.

Precision Insert-Molded Collar Construction

Unlike conventional mechanically assembled insulation collars, our terminals use a precision injection molding process to integrate the plastic collar with the copper sleeve.

Key advantages include:

• Stable Collar Attachment: Helps reduce collar movement and separation during handling.
• Smooth Surface Transition: Consistent molded geometry for easier wire insertion and handling.
• Accurate Positioning: Controlled alignment between the copper sleeve and insulation collar.
• Consistent Production: Repeatable molding supports stable quality and efficient high-volume manufacturing.

Single & Twin Wire Ferrules

Single Wire Ferrules

Designed to terminate one stranded copper conductor. Ideal for electrical cabinets, control panels, terminal blocks and general equipment wiring.

Twin Wire Ferrules

Designed to terminate two conductors of the same cross-sectional size in one ferrule. Suitable for control circuit bridging and common terminal connections where the terminal block permits two conductors.

Vinyl & Nylon Insulation Options

Vinyl-Insulated (PVC): An economical option for general electrical wiring, with a maximum operating temperature of up to 75°C according to product specification.

Nylon-Insulated: Offers tougher insulation and higher temperature capability, up to 105°C according to product specification.

Different insulation colors and conductor size identification systems are available for specific market requirements.

Typical Applications

• Electrical control panels and distribution cabinets
• PLC and industrial automation systems
• Machinery and equipment wiring
• Screw and compatible spring-clamp terminal blocks
• Electrical assembly and maintenance
• Twin-wire bridging and control circuit connections

Choose the Right Wire Ferrule

Select according to the conductor cross-section, number of wires, copper sleeve length, insulation type and terminal block requirements.

Use a compatible crimping tool and verify terminal block compatibility before installation.

Frequently Asked Questions

1. What are cord end terminals used for?

Cord end terminals are used to crimp and protect stranded copper wire ends, helping prevent stray strands and improving insertion into compatible terminal blocks.

2. What is the difference between single and twin wire ferrules?

Single ferrules terminate one conductor, while twin ferrules accommodate two conductors of the same cross-section in one common sleeve.

3. What is the advantage of injection-molded insulation collars?

The molded construction helps maintain accurate positioning, a smooth collar-to-sleeve transition and stable attachment during handling and installation.

4. What is the difference between vinyl and nylon insulated ferrules?

Vinyl is a cost-effective insulation option for general wiring, while nylon offers tougher insulation and higher temperature capability, depending on the material specification.

5. Can I order different insulation colors?

Yes. DIN, French, German and customized color coding systems are available according to order requirements.
