PCM-XY-0007 is an automotive Ethernet breakout harness developed by Premier Cable. It features an Aptiv 35570183 four-port female connector at the main end and branches into four Aptiv 35191760 single-port female connectors. The assembly uses LEONI Dacar 647-4 automotive data cable to integrate multiple connection requirements into one pre-assembled harness.

For automotive electronics development and OEM harness integration, this configuration provides a common main interface for four separate physical connection points, making it easier to plan individual branch routes around equipment layouts. Compared with procuring and installing separate cables for each connection, a pre-assembled 1-to-4 harness can simplify material configuration and standardize port identification, wiring assignments, and quality inspection.

Importantly, a passive 1-to-4 harness is not an Ethernet switch and does not mean that one network port can directly serve four devices. The assembly establishes four physical connection paths according to a defined pin mapping. Suitability for a target network must be confirmed against the electrical definitions of the four main-end interfaces, device port configurations, and network topology.

Premier Cable can evaluate OEM customization based on interface configuration, cable length, pin assignments, and testing requirements, supporting sample development and volume supply for automotive electronics manufacturers, system integrators, and harness buyers.

Product Overview

PCM-XY-0007 is a pre-assembled 1-to-4 automotive data harness developed for projects where multiple interfaces are concentrated at one controller or device but require separate routes to different installation locations. When the main interface, four pin groups, and target equipment meet the design requirements, it establishes four physical connection paths between the main connector and the four branch connectors.

By combining these paths into one assembly, PCM-XY-0007 helps reduce repetitive termination and installation work while standardizing the bill of materials, interface configuration, cable lengths, and inspection procedures. This simplifies procurement, assembly, maintenance, and replacement for OEM and volume projects. As a passive harness, it does not actively duplicate or switch data.

Product Features

Four-Port Main Connector Configuration

The Aptiv 35570183 four-port connector organizes four interface groups within one main-end component. Compared with installing multiple separate main-end connectors, this arrangement helps centralize interface positioning and harness routing, depending on the equipment design.

Four Separate Single-Port Branches

All four branch ends use Aptiv 35191760 single-port connectors. Each branch can be routed separately according to equipment interface locations, making it easier to distinguish P2, P3, P4, and P5 and manage their respective wiring assignments.

Specified Automotive Data Cable

LEONI Dacar 647-4 as the cable material. A defined cable model helps customers verify the bill of materials, cable documentation, and replacement requirements. The LEONI Dacar family is designed for in-vehicle data communication, while application suitability must be confirmed for the specific cable variant and complete assembly.

Why Choose a 1-to-4 Automotive Ethernet Breakout Harness ?

When automotive electronic equipment requires four interface groups to be routed to different locations, PCM-XY-0007 can serve as a centralized pre-assembled harness solution. Compared with procuring four separate cables, a unified assembly helps standardize connector configurations, wiring drawings, length tolerances, and quality records, while making individual branches easier to identify during installation and maintenance.

However, the 1-to-4 harness establishes four physical connections according to the drawing; it does not provide active network switching or data duplication. Selection must therefore confirm that the four interface groups of Aptiv 35570183 correspond to the required independent channels and that the equipment design permits a passive breakout harness. Systems requiring active data forwarding need an appropriate network switch.

Product FAQ

Can a 1-to-4 Automotive Ethernet Harness Turn One Port into Four Network Ports ?

The number of connectors alone does not establish this capability. PCM-XY-0007 maps four contact groups at the main connector to four branch connectors, providing four physical connection paths. This does not mean it can actively distribute one Ethernet communication channel to four devices.

Actual automotive Ethernet connectivity depends on controller port design, the number of communication channels, and network topology. If the four contact groups correspond to four independent links, they should be connected according to the system design. If multiple devices must share or exchange data, a network switch or another architecture-compatible solution may be required.

Can All Four Branches Operate Simultaneously ?

This depends on the internal definition of the main interface and the target system architecture. The drawing shows four pin groups routed to four branches, but simultaneous communication requires confirmation that the interface groups correspond to independent channels and that the controller and network design support the intended operation.

Do All Four Branches Use the Same Connector ?

Yes. According to the engineering drawing, P2, P3, P4, and P5 all use Aptiv 35191760 single-port connectors, while P1 uses an Aptiv 35570183 four-port connector. The pin assignments for each branch should follow the approved wiring drawing.

Can Premier Cable Provide OEM Customization and Volume Supply for PCM-XY-0007 ?

Standard lengths, special cable lengths, wiring assignments, and inspection requirements can be evaluated according to project needs. When requesting a quotation, provide the complete main and branch connector part numbers, equipment interface drawings, network topology, and target testing requirements. Customization scope, minimum order quantity, and lead time should be confirmed during technical review and quotation.
