0.5 mm² (22 AWG) Bootlace Ferrules

Where this size is used

0.5 mm² is the cross-section used for sensor, signal and PLC input wiring. A ferrule at this size does the same job as at any other: it binds the strands into a solid pin so the terminal clamps metal rather than a spreading bundle.

The part is the same whether the drawing says 0.5 mm², 22 AWG, 22 gauge, bootlace ferrule, wire ferrule or cord end terminal. What actually varies within this page is pin length, whether there is an insulating collar, and whether one or two conductors enter the barrel.

Collar colour: white. DIN 47002 assigns white to 0.5 mm² under DIN 46228-4. Colour repeats across the standardised range, so it confirms a size rather than identifying one — read the marking on the collar.

0.5 mm² and 22 AWG ferrule models

Part numbers follow cross-section + length: HE0506 is 0.5 mm² with 6 mm of pin. The twin models take two 0.5 mm² conductors into one barrel, so they are not a drop-in alternative to a single-wire model.

Insulated single-wire

A plastic collar over the barrel. The default choice inside a panel, and the only series with any UL 486F coverage. Full range on the HE series page.

Twin (two conductors, one barrel)

One barrel, two conductors of the same size. Confirm the terminal accepts a twin ferrule before specifying one. Full range on the HTE series page.

Non-insulated

A bare tinned copper sleeve with no collar, so no colour coding and a shorter overall length where terminal entry is tight. Full range on the HEN series page.

AWG values are catalogue and packaging labels, not mathematical conversions. Select from the conductor’s marked mm² cross-section wherever it is available. The full standard range is set out in the wire ferrule size and colour guide.

Choosing the pin length

Cross-section selects the bore; it does not select the length. Every model above accepts the same conductor, and the terminal decides which one fits. Take the stated ferrule length from the terminal manufacturer’s data, or use its strip length as the compatibility basis and confirm the pin length rather than assuming the two are equal.

SN-06WF covers the 0.5 mm² range. The crimp profile, not just the tool, decides whether the joint passes inspection — see the ferrule crimping guide for preparation and inspection steps, and what a crimping tool does for how the die shapes compare.

Colour coding and UL coverage

cULus Listed to UL 486F covers HE0506, HE0508, HE0510, HE0512. The twin and non-insulated series are outside the listing entirely. All models at this cross-section are supplied with RoHS and a CE Declaration of Conformity as standard; the UL certificate is supplied with the quotation.

Colour is a confirmation, not an identifier: DIN 47002 reuses the same collar colours at several cross-sections across its 0.5–50 mm² range. The differences between colour standards are set out in the size and colour guide.

Ordering

• Sold by the pack. Pack quantity differs by series and length; each figure is listed in the table above.

• Factory packs are not split by the manufacturer.
• Mixed-size boxes covering this cross-section are listed under the wire ferrule kits.
• Not sure which series or pin length fits your terminal? Use the wire ferrule selector to filter by conductor size and requirement.
• Model-specific Declaration of Conformity and supporting compliance documents can be reviewed with the quotation.

FAQ

Which ferrule fits 0.5 mm² wire?

A ferrule labelled 0.5 mm², listed as 22 AWG in North American catalogues. Termnex lists 11 models at this cross-section across the insulated, twin and non-insulated series; they differ in pin length and collar, not in the conductor they accept.

What pin length should I use for 0.5 mm²?

The terminal decides, not the wire. Insulated models at this size come in 6 mm · 8 mm · 10 mm · 12 mm. Take the ferrule or strip-length requirement from the terminal manufacturer’s data and match it. See ferrule pin length.

Is a 0.5 mm² ferrule the same as a 22 AWG ferrule?

Yes. The part is manufactured to a metric standard and marked in mm²; 22 AWG is the catalogue label used for the same part in North America. There is normally no separate 22 AWG part number. The same size is also written as 22 gauge — a ’22 gauge wire ferrule’ is this page, not a different part.

What colour is a 0.5 mm² ferrule?

DIN 47002 assigns white at 0.5 mm² under DIN 46228-4. Colours repeat across the range, so confirm the size marking rather than relying on colour.

Are 0.5 mm² ferrules sold individually?

No. They ship in factory packs; the pack quantity is listed against each model in the table above. Evaluation quantities and commercial terms are confirmed with the quotation.
