MX34 Automotive Connector 12 Way – Non-Waterproof Board-to-Cable Connector, Tin or Gold Plated

Part number 2201AM-2X06-ESGY MX34 Automotive connector describes exactly what you get: two rows of six positions, twelve circuits in total. It is a non-waterproof board-to-cable connector, which means a header sits on the PCB and a crimped-wire housing plugs into it from the harness side. The housing is not sealed, so it belongs in dry locations: inside the cabin, or inside a closed module such as an ECU case, a switch pack or an instrument cluster.

If your connector will sit in the engine bay or anywhere it can be splashed, you need a sealed family instead. Our 12 pin waterproof automotive connector covers that case, and the guide on waterproof automotive connectors explains how sealing levels are chosen.

The MX34 name comes from JAE’s compact automotive series. JAE describes the family as a small, high-density, non-waterproof line for interfaces such as body and chassis ECUs, switches and sensors (see the JAE product release). Buyers who have this series written into a drawing often need a second source, and that is the job of this part: same format, same mating logic, supplied from Shenzhen with short sample lead times.

Because the part follows the MX34 format, it works with the crimp terminals already used for that series. Our MX34 crimp terminal page lists the matching contacts, so the housing and terminals can be quoted together.

A 12 pin automotive wire-to-board connector in this style is common wherever a small control module needs a removable harness connection. JAE lists electronic control units, meters, lighting, navigation, audio and air conditioning as typical uses for the MX34 series (DigiKey product highlight), and the same list applies here.

Transport and industrial equipment with similar vibration and packaging requirements, such as trailers, work vehicles and control cabinets, also use this format.

Tin is the usual choice for power and general-purpose signal lines. It costs less, and when both mating contacts are tin the joint behaves predictably. Gold makes sense on low-voltage, low-current circuits, such as sensor inputs, where a thin oxide layer on the contact could raise resistance enough to distort the reading.

The one rule to follow is to keep the plating the same on both sides of the mating pair. Mixing tin and gold invites fretting corrosion in a vibrating environment. When you send an inquiry, state the plating of the mating header or terminal, and we will match it.

A connector housing is only half of the joint. The other half is the terminal and the wire crimped into it, and both must match the housing. Tell us the wire gauge and insulation type, and we will point you to the right terminal from the MX34 crimp terminal range.

If you would rather receive finished harnesses, our team also builds cable assemblies to your drawing. For projects on a 2.0 mm grid, see the 2.0mm pitch wafer auto connector, and for surface-mount boards look at the 20 pin automotive wafer connector SMT. Working on a high-voltage platform? The EV battery connector guide covers that side of the vehicle.

Send us the part number, plating, the quantity you need and your target delivery date through the contact page, or use the Get a Quote button at the top of this page. If you are replacing an existing JAE part, include its full part number so we can check compatibility on our side first.

Samples are available for engineering evaluation. We normally reply within one working day with pricing, lead time and a datasheet.
