JAE Europe has enhanced its MX34 series automotive connector family to handle higher currents and to ease assembly. It has also embarked on testing for qualification to the USCAR standard. The MX34 current rating has been increased more than 200% to 10A per way dependent on derating curve* and the maximum operating temperature range has also risen, to 105ºC. The connector headers are now plated on all four sides, which simplifies the wave soldering process. Other connectors typically have their pins stamped, leaving two sides open as bare metal.

The trend to increase functionality whilst minimising the size of electronic control units (ECUs) has resulted in connectors becoming the limiting factor in the reduction of ECU package size. Consequently, there is now a lot of interest from automotive manufacturers in small format connectors, such as MX34, that are able to withstand high currents.

The JAE MX34 series low profile connectors are aimed at cabin applications where any space saved maximises the room available for the car occupants. Typical uses are for rear-seat mounted entertainment systems, and roof-mounted sensors for alarms and rain-sensitive windscreen wipers.

High density PCB-to-cable interconnects are achieved by utilising a 2.2mm contact pitch and a double row of contacts, together with JAE’s in-house thin-wall moulding technology. The MX34 series connectors are available with between 3 and 40 contacts.

The choice of a straight or right-angle pin header allows use in a wide range of applications and locations. The robust miniature box-section pin headers, together with double leaf spring contacts that are highly resistant to twisting, and a preset-type secondary locking mechanism enable rapid, failsafe assembly. A lock spring is also provided, featuring a bridge to protect the contacts from external load.

MX34 series connectors operate from –40 ºC to +105 ºC, provide insulation resistance greater than 100 MΩ and dielectric withstand voltage 1000 VAC for one minute. Maximum contact resistance is 5 mΩ, and durability is 50 insertions.
