Type2 to NACS Adapter for Single-Phase AC Charging

Last updated: 13 September 2026

Overview

A Type2 to NACS adapter joins a vehicle inlet built to one AC coupler
family to charge-point hardware built to the other. One end is an IEC 62196-2 Type 2 coupler,
the other is a connector built to the North American Charging Standard interface published as
SAE J3400. It carries single-phase AC and nothing else: it does not convert AC to DC, it does
not add current, and it does not turn a charge point into something it was not built to be. We
supply compatible components and build to the pinout, conductor size and length on your
drawing. We are not affiliated with any vehicle maker, and the interface names belong to their
respective owners.

Key Specifications

Adapter, charging cable, and vehicle inlet are three different parts

Most of the confusion around this product comes from mixing up three things that sit in the same
photo. The inlet is the socket on the vehicle, the charging cable is the assembly with control
electronics at the wall end, and the adapter is a passive length of cable with a coupler at each
end. Separate those three and the questions get easy.

The session always runs at the lower of the two limits. If the charge point offers one current
level and the vehicle accepts another, you get the smaller value, and that is correct behavior
rather than a defect.

Single-phase AC: what each Type 2 contact does

IEC 62196-2 gives the Type 2 interface seven contact positions. Three of them are always the
same, and the other four are allocated according to the operating mode. In single-phase AC
charging, four of the seven carry the work.

The Type
2 connector family is defined in IEC 62196-2 and, in its AC signaling, follows the same
control pilot and proximity pilot logic described in SAE J1772 and IEC 61851-1. That shared
signaling is why a passive adapter can work at all: both ends are already speaking the same
analog language, so nothing has to be translated.

Why this build is single phase only

A single-phase AC adapter carries one phase, the neutral, protective earth and the two
signaling contacts. Three-phase AC is a different cable with three phase conductors. DC charging
is different again: sessions run at currents where every extra contact set is a thermal risk, and
the signaling is digital rather than PWM. Our build does not populate DC contacts.

Construction

• Conductors: 3 x 6 mm2 power plus 1 x 0.75 mm2 signal as standard; 3 x 10 mm2 for the
  higher-current build.
• Jacket: TPU in black, chosen for oil, road salt and the abrasion of being dragged across a
  driveway or a workshop floor.
• Length: 5 m standard, other lengths to order.
• Molded coupler bodies with integrated strain relief, and a cap for the vehicle-side
  connector.
• Signaling contacts wired straight through, so the station and the vehicle still negotiate
  directly.

Inspection and care

An adapter adds one contact set to a high-current path, so inspect the coupling faces before
every session: pitting, discoloration, a loose fit, or a latch that no longer holds. Seat each connector until it latches and
let the cable hang from its own strain relief. Store it coiled off the ground with the caps on.
Do not use one that has been run over, cut or crushed, and do not use one to extend a lead that
is already at its limit.

How to specify your build

1. Inlet and socket — which coupler is on the vehicle and which is on the
   charge point you need to reach.
2. Current and conductor size — 32 A as standard, or state the figure you
   need.
3. Length, and whether it is a driveway, depot or worksite run.
4. Direction — Type 2 to NACS, or the NACS to J1772 reverse build.
5. Quantity, and whether this is a sample or a production order.

Typical applications for this Type2 to NACS adapter

• Fleet depots where the charge posts and the vehicles were bought to different standards
• Home and workplace charging where the wallbox lead is fixed and the vehicle inlet changed
• Worksite and temporary charging where a generator-fed station meets mixed vehicle types
• Vehicle preparation and logistics yards alongside our V2L
  discharge adapter cable from Type 2 inlet to AC sockets
• Distributor programs that need a private-labeled adapter with their own part number

Workmanship and testing

Our line is ISO 9001 certified and every assembly is built to IPC/WHMA-A-620 Class 3 workmanship across 32 to 12 AWG. Continuity and pinout are checked on every unit before packing, and seal checking can be quoted where an ingress rating is specified.

Custom builds and ordering

Prototypes are quoted from 5 pcs and ship within 3 working days. Volume production starts at 500 pcs with a 14 working day lead time after approval, and about 10 working days more when a new tool is needed. Private labeling carries your part number, and material certificates with first-article reports are available on request.
