PCM-ZC-0181 is designed for dual-channel connectivity between advanced driver-assistance processors, domain controllers and other high-speed data equipment. It connects one dual-port GEMnet Z-coded interface to two separate A-coded branches, providing a compact physical breakout solution for devices with a corresponding dual-channel architecture.
By consolidating the main connection into a single interface, the design reduces repetitive connector arrangements and additional adapter requirements while allowing each branch to reach sensors or electronic modules at different locations. This helps optimize equipment space, harness organization and assembly efficiency.
Stable Connectivity
Locking down a strict 100 Ohm nominal characteristic impedance across its entire span, this wire harness supports an ultra-wide spectrum spanning from DC to 10GHz. This precision calibration allows for near-zero loss conduction of Multi-Gigabit (10Gbps+) automotive Ethernet protocols, maintaining an exceptionally suppressed Bit Error Rate (BER) and flawless signal integrity amidst tight, EMI-heavy electronic clusters.
Operational Lifespan
The total split harness assembly perfectly satisfies severe tier-1 automotive environmental weathering audits, exhibiting an operational envelope from -40°C to 105°C. The specialized LEONI insulation compound provides superb thermal-aging blocks and resistance against auto-fluid ingress, preventing coat cracking or dielectric drift even when routed adjacent to sizzling domain control computing bays for decades.
Installation Requirements
To accommodate distinct layout runs ranging from central gateways to rear LiDAR arrays or roof telematics units, this portfolio provides off-the-shelf options of 0.5m, 1m, and 2m. The TE-engineered housings come keyed with unique mechanical Code Z and Code A blind-mating rails and latches, allowing field technicians inside dark dashboard channels to guarantee fully locked connections simply by acoustic click feedback.

Dual-Port GEMnet Z-Coded Main Interface
The TE 1-2386612-4 dual-port Z-coded Jack consolidates two connections into one main interface for equipment with a corresponding dual-channel configuration. Exact mating compatibility must be verified against official drawings.
- Dual A-Coded Breakout Branches
Two TE 2368003-1 A-coded Plugs form separate breakout branches for compatible devices at different locations. Each branch's signal correspondence must follow the customer-approved pin mapping.
- LEONI Dacar 686-3 Cable
LEONI Dacar 686-3 provides a 100Ω nominal impedance and DC–10GHz frequency range as the cable foundation for compatible high-speed differential links. Actual data rates require complete channel validation.
- Multiple Lengths and Wide Temperature Range
Available in 0.5m, 1m and 2m lengths with a -40°C to +105°C operating temperature range, supporting different equipment spacing and project-specific length customization.
Core Application Scenarios
Automotive Domain Controllers and Centralized Electronics
Suitable for domain controllers, central computing units or automotive electronic modules with defined dual-port GEMnet interfaces, the harness routes the main multi-port connection to two compatible devices. It helps organize wiring in connector-dense controller areas and provides clearly identified channel connections for distributed equipment. The Ethernet PHY, protocol and channel mapping must match the equipment design.
ADAS Camera and Sensor Data Connectivity
The assembly can support high-speed differential connections between compatible ADAS cameras, sensors and data-processing modules. Its dual-branch structure is useful when a centralized equipment interface must route to two separate installation locations. Compatibility with specific cameras, LiDAR, RADAR or SerDes protocols requires verification of equipment interfaces, pinout and complete channel performance.
Core Performance Advantages
Improved Wiring Organization
Dual-channel branching reduces cable crossings and improves assembly and maintenance efficiency.
Simplified Connection Path
Directly connects compatible devices, reducing adapters and intermediate connection points.
High-Speed Link Validation
100Ω impedance and DC–10GHz frequency range support differential link validation.
Flexible Project Configuration
Multiple lengths and custom configurations accommodate different equipment layouts and OEM requirements.
Frequently Asked Questions
Q1：Is PCM-ZC-0181 an Ethernet Switch or Network Splitter ?
A1：No. It is a passive dual-channel physical breakout harness without a switching chip, PHY or protocol conversion. Two destination devices can operate independently only when the host provides the corresponding separate channels and the pin mapping is correct.
Q2：Is It Compatible with All GEMnet Equipment ?
A2：No. Port count, coding, mating part numbers, terminal types, pin assignment, impedance and protocol requirements must be verified. Similar connector appearances may still correspond to different channel definitions or electrical configurations.
Q3：Can Different Lengths or Branch Structures Be Customized ?
A3：Custom configurations can be evaluated for OEM projects. Provide equipment interface drawings, exact mating part numbers, pin mapping, target lengths, installation clearance and high-speed channel requirements to confirm the design, prototype and testing plan.
