The AWG value is the supplier catalogue reference, not a mathematical conversion. Select HEN4012 from the conductor’s marked 4 mm² cross-section first, then compare a 12 mm barrel with the terminal maker’s accepted ferrule and strip-length requirements.
4 mm² bare ferrule with a 12 mm barrel
The model code is direct: 40 identifies the 4 mm² conductor size and 12 identifies the nominal barrel length in millimetres. HEN4012 suits terminals that accept a 12 mm barrel.
Compliance and ordering
HEN4012 is not UL Listed. The UL 486F listing covers the HE insulated single-wire series only, and the non-insulated range is outside it. HEN4012 is supplied with CE and RoHS documentation. If the panel requires a UL Listed ferrule, specify the equivalent HE series instead.

FAQ
What does HEN4012 mean?
HEN identifies the non-insulated ferrule series – a bare tin plated copper sleeve with no collar. The 40 size code identifies the 4 mm² conductor size and 12 denotes a 12 mm barrel.
When is a non-insulated ferrule the right choice?
Where the terminal or enclosure already provides strain relief and insulation, or where collar height would not fit. The colour coding and strain relief of an insulated ferrule are given up in exchange.
Is HEN4012 UL Listed?
No. The supplier confirms UL 486F covers the HE insulated series only; the HEN non-insulated series is not UL Listed. It is supplied with CE and RoHS documentation.
Is HEN4012 a bootlace ferrule?
Yes. Wire ferrule, bootlace ferrule, cable ferrule and cord end terminal are common names for this type of stranded-wire termination.
Which crimp tool covers HEN4012?
SN-06WF covers the 4 mm² range that includes HEN4012. Verify the finished crimp against the conductor and terminal requirements.
Is HEN4012 sold individually?
No. The standard factory pack contains 1,000 pieces. Small evaluation quantities and commercial terms are confirmed with the quotation.
