Hybrid connectors target next-gen vehicle architectures

Molex’s new MX-DaSH family of data-signal hybrid connectors, combining power, signal and high-speed data connectivity in a single connector system, targets next-generation automotive architectures. These wire-to-wire and wire-to-board connectors support the transition to zonal architectures and address emerging applications that require reliable data transmission. These include autonomous driving modules, camera systems, GPS and infotainment devices, LiDAR, high-resolution displays and sensor-device connectivity.

In addition to offering savings in size, space and cost by integrating power and high-speed data transmission in a single connector system, the MX-DaSH family offers greater design flexibility with different terminal types and size, allowing designers to mix-and-match connectors across different vehicle designs and applications.

The MX-DaSH connectors are available with sealed and unsealed options to meet different environmental and design requirements. Configurations support different power and signal terminal sizes, such as 0.50, 0.64, 1.20, 1.50, 2.80 or 4.80mm, as well as high-speed FAKRA Mini (HFM) modules for high-speed data transmission.

For greater reliability, MX-DaSH wire-to-wire connectors feature male blade stabilization and independent secondary locks for reliable terminal mating. These connectors also offer modular sections or cartridges in the wire-to-board option that support various interfaces without changing form factors or footprints. This enables automotive engineers to accommodate a growing mix of devices and sensors with different network requirements, Molex said.

The MX-DaSH family also helps to reduce wiring harness cost and weight as well as design complexity. One example cited is the reduction in the number of inline, wire-to-board connectors from eight to two for an instrument panel and body control harness, while removing up to six meters of copper wiring, depending on the specific vehicle model.

In addition, multiple options in the connector system include a variety of wire-to-wire applications. One example is the 31+1-Way connector system that combines 31 power and ground circuits, as well as a high-speed data connection, to decrease packaging requirements by up to 30%, Molex said. This higher functionality translates into time savings through streamlined harness installations, while fewer component requirements offer a further reduction in the bill of materials.

The MX-DaSH connectors have been validated in accordance with global industry standards groups, including USCAR, Peugeot and IEC, to ensure reliable performance in harsh automotive environmental conditions. The wire-to-wire connector models are available, along with select wire-to-board models and custom configurations. Continued product expansion is underway to meet evolving vehicle connectivity requirements.
