Rewiring the Road: Unlocking the Power of 48V

Gain deeper insights into the transformative potential of 48V technology and its impact on the future of automotive design. This new report discusses how this emerging technology supports advanced features such as electric turbocharging, regenerative braking and sophisticated infotainment systems. These capabilities enable automotive manufacturers to meet the surging demand for more electronic features while helping to ensure reliable power distribution and vehicle functionality. This makes the shift from 12V to 48V systems critical to the evolution of automotive technology.

MX150 Connectors: Beyond the Garage

MX150 Connectors are highly versatile, offering up to 20 circuits in various wire-to-wire and wire-to-board configurations suitable for a wide range of applications. Designed for harsh environments, they can withstand high vibration conditions and temperatures of up to 125°C (260°F), which makes them ideal for fuel injection modules, traction control systems, brake calipers and general under-the-vehicle wiring applications in the automotive environment. Higher voltage versions of the connector offer a twist lock and multiple terminal sizes, enabling them to adapt to varied durable power and connectivity needs for powersports and even home appliance applications.

Frequently Asked Questions

What makes MX150 Connectors different from the competition?
With the mat seal technology, MX150 Connector System is significantly smaller than other comparable USCAR connectors, making it valuable for engineers struggling with space constraint challenges.

How does the Molex MX150 Pass-Through Sealed Connector design provide superior sealing performance?

  1. The design uses potting in the terminal interface.
  2. The unique two-ring seal option delivers redundancy when compared with typical single-ring sealed connectors.
  3. The two-lip ring seal design provides a more reliable seal.
  4. The anti-oil seal is designed specifically for oil-cooled motor applications.

Why do MX150 Pass-Through Sealed Connectors use a stackable 2 by 3 connector design?
The stackable design includes a connector for the temperature sensor assembly and a connector for the rotary transformer assembly. With other designs, these sub-assemblies are provided by different suppliers. With MX150 Pass-Through Connectors, the combined design provides procurement flexibility and helps reduce supply chain risks.
