Würth Elektronik ICS introduces PCB-based splitter for reliable vehicle ground connections

Würth Elektronik ICS has introduced the Splitter C2-PE4, a compact PCB-based module designed to improve the reliability of ground and power distribution connections in commercial vehicles and mobile machines.

Loose or corroded ground connections can create recurring problems in vehicle electrical systems. Corrosion, vibration and wiring errors can lead to unstable connections, maintenance issues and electrical faults. The Splitter C2-PE4 is designed to reduce these risks by allowing multiple ground signals to be collected at a single contact point with the vehicle chassis.

Instead of using several grounding points, small screw connections and multiple splices in the wiring harness, the module brings ground connections together at one location and at the same electrical level. This can simplify vehicle electrical architecture and reduce the number of chassis interfaces.

The solution is also relevant for electric vehicles using non-metallic chassis structures to reduce weight. In these cases, collecting ground signals through the chassis can be more complex, making centralized distribution modules useful for system integration.

The Splitter C2-PE4 supports up to 70 signal lines and up to four power lines. Each pin can handle up to 15 A, while the module is designed for continuous currents of up to 200 A. It can be used for both GND and +BATT signal distribution.

The module measures 155 × 115 × 45 mm and is designed with IP66 and IP69K protection classes. These ratings support use in demanding environments where exposure to dust, water, cleaning processes and vibration must be considered.

By reducing wiring complexity and improving the reliability of ground and power distribution, PCB-based splitter modules can support safer and more maintainable electrical systems in commercial vehicles, mobile machines and electric vehicle platforms.
