Wire ferrules appear in electrical component lists, but a collar color alone is a poor spare-parts specification. Keep the complete component reference and its documented conductor and terminal context when comparing an offered replacement.
For an aluminum-cutting machine, this is a purchasing and service-record question. The qualified electrical team should define and review the connection. The buyer can make that review easier by ordering against a clear reference instead of a photograph of a colored sleeve.

What wire ferrules do in the referenced guide
Phoenix Contact’s April 2023 ferrule poster describes sleeves that bundle conductor strands and help insertion into terminals. It shows insulated, uninsulated and TWIN versions. Collar colors vary between coding systems; TWIN ferrules accommodate two conductors of the same cross-section.
The poster cautions against crimping aluminum conductors with copper ferrules. It also explains that a crimp form can create a fit issue at the maximum terminal cross-section, and that its stated UL certification concerns selected ferrule-and-tool combinations.
These points explain why the part, conductor, terminal and processing-tool references belong together. They do not identify the electrical components installed in any JiurunCut machine.
Check 1: read the color system before selecting a size
A fictional spare-parts request says “white ferrules, same as before.” The buyer has a clear photograph of a white collar, but the original package and service part number are missing. Keep that request open while the qualified service team resolves the exact reference.
The poster’s comparison shows why: white denotes 0.50 mm² in its DIN/UL color column and 0.75 mm² in its NF C column. This is a comparison from the source chart, not a size recommendation for the fictional machine.
Ask for the manufacturer, full part number and declared conductor specification. Use the collar color as supporting identification. Do not let a color match overwrite a different size in the product data.
If the existing package is available, retain its label image and reference. When it is unavailable, keep the missing information visible. A partly identified item should stay partly identified until the responsible reviewer can close the gap.
Check 2: retain conductor material in the spare-parts record
The machine processes aluminum stock, but that fact does not identify the material of an electrical conductor. Keep the electrical component record separate from the workpiece description.
Ask the service team to identify the conductor involved and the approved termination component. Keep those references with the terminal information. A request for an “aluminum machine ferrule” does not describe the connection accurately enough for a substitution review.
In a fictional supplier reply, the offered sleeve material differs from the approved record. Highlight that difference rather than accepting the offer because its collar looks familiar. The responsible electrical reviewer needs the actual component information to answer the compatibility question.
Use the exact product documentation when communicating the proposed item. Do not infer sleeve material from a silver-colored surface or from a generic product photograph.

Check 3: compare the complete form and supply scope
Separate the sleeve form, sleeve length, collar description and conductor entry in the offered component data. Keep each entry connected to the complete part number. An abbreviated catalog label can be useful, but the full record should remain available.
Ask whether the offer concerns a single-conductor or two-conductor component, and identify the terminal where it is intended to be used. Leave the connection arrangement to the qualified electrical team; this guide provides no wiring instructions.
When the seller offers a different length or form, record that proposal explicitly. Keep the original service reference beside it, so the reviewer can see what changed. Similar package colors or quantities should not hide a different component.
| Fictional item description | Information still needed |
|---|---|
| White collar only | Full part reference and applicable color system. |
| Same size, different sleeve | Documented form, length and proposed terminal context. |
| TWIN version proposed | Responsible review of the intended conductor arrangement. |
| Equivalent replacement | Named proposed item, documented differences and approved decision. |
This table organizes fictional purchasing descriptions. It is not a terminal compatibility chart or a list of approved components.
Check 4: keep the ferrule and tool combination documented
When the electrical team specifies a processing system, retain the component and tool references together. Ask the supplier what combination its quoted evidence covers. A general certification logo on a catalog page does not identify the complete proposed combination.
Keep the approved preparation and verification instructions in the service documentation. This article gives no strip length, crimp setting, terminal torque or test-force requirement. Those details belong to the actual connection and qualified work procedure.
If a tool or component changes, ask for a review of the changed combination. Record the result under the same service question, so purchasing and maintenance can see the current approved scope.
At receipt, compare the package identification with the confirmed order. Keep an unresolved difference out of the approved spare-parts list until the responsible team has answered it. The aim is a readable record, not a buyer’s improvised electrical test.

A simple decision for a replacement request
- Exact approved reference offered? Retain the offer and delivery identification with the service record.
- A documented alternative offered? Send the full proposed reference and differences to the responsible electrical reviewer.
- Only a color or photograph available? Keep the request open and recover the missing identification.
The machine spare-parts guide helps organize the broader service inquiry. The cable-carrier guide addresses a separate routing question, while the analog signal guide addresses interface documentation.
Contact JiurunCut with the machine identity and available service references. State whether you need the original spare, a proposed alternative or help resolving incomplete identification. Keep the electrical connection decision with the qualified team responsible for it.
