E-Powertrain

Suyin’s custom-made connectors for e-power management modules such as DC/AC traction power inverters, bidirectional DC/DC converters, and high-voltage battery management controllers meet all the requirements for the aggressive environmental conditions in vehicles such as vibration, temperature fluctuations, and humidity.

  • Seal protection up to IP6K9K achieved via insert-molded contacts with application-specific back-potting
  • Housing material allows high working temperatures up to 150 °C
  • Vibration resistance up to 40 G achieved via rigid-flex cable connection between boards
  • High torque force beyond your requirement for cable lug or busbar connection to 12 V (KL30), 48 V (KL40) and GND (KL31/KL41) via class-10.9 bolts
  • For PCB mounting, Suyin offers both solder mounting connectors with optimized plating selection to reduce tin whisker risk, and certified press-fit contacts.

E-Charging

For the design of electric powertrains the efficiency of the electric systems is of utmost importance to achieve the maximum possible driving range, power consumption efficiency and shortest charging times. In the domain of electrical efficiency, one key area is the efficient thermal management of connectors – reducing temperature rise while being lighter in weight and less bulky than conventional connectors.

With our customized connectors for next-generation mobility, Suyin is highly engaged in supporting the development of a more sustainable and safe future.

Conventional ICE Powertrain

Suyin’s custom-made powertrain connectors withstand aggressive environmental conditions in vehicles such as vibrations, temperature fluctuations and humidity. A particular advantage of Suyin custom products is the integration of several individual connector interfaces into one multi-connector with high contact density and multiple contact sizes. This reduces the effort required to assemble and seal the individual connectors in your production and also makes the management of your supply chain much more efficient.

  • Seal protection up to IP6K9K achieved via insert-molded contacts, with back-potting
  • Ultrasonic-welded venting membrane to avoid humidity caused by air pressure changes in your device
  • Production, inspection and packing in a clean room to meet customer cleanliness requirements
  • Audible click feature confirms the connection in position even under blind mating
  • Connector housing material allows high working temperatures up to 150 °C
  • Meet automotive specifications VW75174 (LV214) and USCAR-2

Steering Control

Suyin custom-designed connectors support various steering control systems like electric power steering, steering wheel locking and steering angle sensors:

  • One single connector with multiple interfaces including torque, CAN and power contacts eases your challenge to meet the leakage level of the whole control unit, increase your production efficiency, and to also reduce effort and cost in your supply chain compared to separate connectors
  • Insert-molded contacts and back-potting ensure IP6K7 sealing class
  • Angled interface and contact design allows maximum flexibility of your system’s mechanical design
