In December 2025, Molex introduced the MX-DaSH modular wire-to-wire connector, a cartridge-based hybrid connection platform that unifies power, signal, and high-speed data into a single connector system. Designed specifically for zonal architectures in modern vehicles, this innovation reduces unique part counts, cuts wiring harness weight and size, and delivers cost savings for automakers.
For suppliers and buyers of cable protection components – including plastic corrugated conduits and cable glands – Molex’s announcement signals a broader industry shift toward modularization, weight reduction, and architectural simplification. This article explains how these trends affect your component choices and why Houxu Yangsheng’s products are well-suited for next-generation wiring systems.
Understanding Zonal Architectures
Traditional vehicle wiring uses a centralized architecture: a main engine control unit runs individual wire bundles to every sensor, actuator, and light across the vehicle. This approach requires long wire runs, heavy bundles, and hundreds of unique connectors.
Zonal architectures divide the vehicle into physical zones (front-left, front-right, rear, etc.). Each zone has a local controller that communicates with the central computer via data links. Within each zone, shorter wire runs connect local components. This reduces total wiring weight, simplifies assembly, and enables over-the-air updates.
How Zonal Architectures Change Conduit and Connector Requirements
When wiring runs become shorter but more concentrated in specific zones, the demands on cable protection change:
1. Higher density: More wires and connectors occupy less space. Conduits must be flexible enough to route through tight areas but strong enough to protect against abrasion.
2. Mixed cable types: Power cables, data cables, and sensor wires may share the same conduit. The conduit must provide adequate separation or shielding to prevent electromagnetic interference.
3. Environmental sealing: Zonal controllers are often mounted in non-protected areas (engine compartment, wheel wells, underbody). Conduits and connectors entering these controllers must provide reliable waterproofing.
Connector Selection Guide for Zonal Applications
When selecting cable glands or connectors for zonal architecture applications, consider these three factors:
Selection Factor What to Look For Why It Matters
IP rating IP67 or IP68 for exterior zones Prevents water ingress at zone controller entry points
Material compatibility PA66 for heat resistance in engine-adjacent zones Withstands elevated temperatures without softening
Installation ease Hand-tightenable designs Speeds assembly in high-volume production
Houxu Yangsheng’s waterproof connectors are rated IP68 when properly installed, making them suitable for exterior and underbody zones. Our PA66 connectors offer excellent heat resistance for engine-adjacent applications.
Application Scenario 1: Electric Vehicle Battery Pack Connections
Scenario: An EV battery pack has multiple zone controllers mounted on the pack housing, each receiving power and signal cables through sealed entry points.
Challenge: Traditional metal cable glands are too heavy and expensive for this application. Plastic alternatives must provide reliable sealing and strain relief while meeting automotive vibration standards.
Solution: Use Houxu Yangsheng’s PA66 cable glands with integrated sealing rings. Lightweight, corrosion-proof, and tested for vibration resistance, they provide reliable sealing at a lower cost than metal alternatives.
Our advantage: Factory-direct pricing allows EV battery manufacturers to reduce component costs without sacrificing quality.
Application Scenario 2: Commercial Vehicle Body Builder
Scenario: A commercial vehicle body builder installs lighting, sensors, and cameras on truck bodies. Each component requires a conduit run from the body to the chassis zone controller.
Challenge: The installer needs conduits and connectors that are easy to work with in the field, without special tools. They also need multiple size options to accommodate different cable counts.
Solution: Specify Houxu Yangsheng’s corrugated conduits (AD10.0 to AD54.5mm) with matching straight or 90-degree connectors. Hand-tightenable installation saves time on each connection.
Our advantage: Wide size range, on-hand inventory for quick shipping, and custom lengths available for large orders.
Corrugated Conduit Selection for Mixed Cable Types
When a single conduit carries both power and data cables, consider:
· Power cables only: Standard PA or PE conduit provides adequate protection.
· Mixed power and data: Use a larger conduit diameter (AD21.2 or larger) to allow physical separation between cable types.
· Sensitive data cables: Consider using shielded cables inside non-shielded conduit, or request special-order conduit with integrated shielding.
Houxu Yangsheng offers conduit in multiple materials – PA (high flexibility, good fatigue resistance), PE (economic, good chemical resistance), and PVC (cost-effective for indoor applications). Our technical team can recommend the optimal material and diameter for your specific cable mix.
The Weight Reduction Opportunity
Molex’s MX-DaSH connector reduces weight by consolidating multiple connector types into one. Similarly, choosing plastic cable glands over metal can save significant weight on a vehicle.
Component Typical Metal Option Houxu Yangsheng Plastic Option Weight Savings
M20 cable gland Brass, ~80g PA66, ~15g ~65g per unit
1-meter conduit segment Not applicable (metal conduit heavy) Plastic conduit, ~50g N/A
For a vehicle with 50 cable entry points, switching from brass to plastic glands saves over 3 kilograms – a meaningful reduction for EV range optimization.
