XTS Empowers Highly Compact & Flexible Automotive Wiring Harness Automation

Introduction

With the rapid iteration of automotive electrical and electronic architectures, zonal wiring systems and miniaturized data cables have become mainstream. Traditional fixed-takt assembly equipment can hardly meet the strict demands of high precision, compact layout, full traceability and multi-model flexible switching for modern vehicle wiring harnesses. Komax SLE, a subsidiary of Swiss Komax Group headquartered in Grafenau, Germany, has launched the Lambda X modular equipment platform. By integrating Beckhoff’s XTS eXtended Transport System and PC-based control architecture, the platform achieves a revolutionary breakthrough in automated wire harness manufacturing, slashing machine footprint while lifting overall production efficiency and product consistency.

1. Lambda X: Modular Platform Tailored for Complex Wiring Assembly

The Lambda X series is a fully modular machine platform supporting semi-automatic and fully automatic assembly of multi-stage contact connectors and complex wiring assemblies. Its hardware, control system and human-machine visualization all adopt modular design, with around 100 standardized process modules and interchangeable contact components. Engineers can freely combine and arrange modules to match diversified cable and connector specifications without extensive rework.

In software architecture, Komax SLE applies the unified Solutions Software Framework compatible with all Lambda equipment and other Komax processing machines. To deliver intuitive, streamlined operation experience, the platform leverages flexible Beckhoff IPC solutions, including fixed CP3921 multi-touch panels and optional movable custom operation panels that can be tilted and shifted across the production line.

All high-precision motion logic on Lambda X relies on high-speed EtherCAT real-time communication. Over 100 controllable motion axes are realized via two drive schemes: AX5000 servo drives paired with AM8000 servo motors, or compact EP7211 EtherCAT drive terminals matched with AM8100 motors. Beckhoff’s One Cable Technology (OCT) drastically cuts cabinet space occupation, while EtherCAT’s free topology, strong stability and broad third-party compatibility simplify overall system integration.

2. XTS Magnetic Conveying System: Core Competitive Edge of Lambda X

Beckhoff XTS serves as the decisive innovation that differentiates Lambda X from conventional wiring processing equipment, eliminating the shackles of fixed beat sequences and enabling dense arrangement of process modules:

2.1 Dramatic Space Reduction

Thanks to XTS, the equipment length is shortened from 20m to 10m, and the overall machine footprint is reduced by up to 45%. The oval XTS track can be configured from 38 to 62 motor modules, supporting a maximum of 60 independently controlled movers to avoid idle waiting during continuous production.

2.2 Bidirectional Flexible Movement

Unlike traditional unidirectional conveyors, XTS movers support reverse operation. For small wire processing scenarios, cables can repeatedly approach the same stripping module without adding extra stations, lowering equipment investment and mechanical wear. The system features low failure rates and long service life, aligning with Komax SLE’s long-lifecycle equipment design philosophy.

2.3 Simplified Commissioning & Quick Product Switchover

Traditional conveyor equipment requires precise alignment of every process module, which costs massive mechanical and sensor debugging labor. XTS’s software configuration eliminates complex mechanical calibration. Combined with deep TwinCAT integration, switching between different cable assemblies takes far less time, greatly shortening production changeover downtime. Equipment developers can design ultra-compact process modules and freely define processing positions without layout limitations from rigid transmission chainsBeckhoff.

3. Future-ready PC-based Control & Integrated Energy Monitoring

The control core of Lambda X is Beckhoff C6032 ultra-compact Industrial PC equipped with Intel® Core™ i7 processor. Its powerful computing capacity covers motion control, HMI visualization, SQL database traceability and carbon emission calculation. Supported by TwinCAT Core Boost and upcoming TwinCAT MC3 multi-core motion control technology, computing tasks can be evenly distributed across multiple CPU cores with adjustable clock frequencies on demand, laying a solid foundation for future function expansion.

The platform integrates EL3443 power measurement terminals and SCT1111-0032 miniature ring current transformers to realize real-time energy monitoring of each process station. Based on collected energy consumption data, manufacturers can accurately calculate power consumption, carbon footprint and CO₂ equivalent per finished wire harness, a critical indicator for automotive OEMs pursuing sustainable production.

For human-machine interaction, Lambda X supports up to two customized CP3921 touch screens connected via CP-Link 4. The panels integrate RFID readers and extended button units, meeting long-term stable operation requirements in automotive workshop environments.

4. Application Value for Automotive Wiring Manufacturers

1. Higher Consistency & Miniaturization Capacity: XTS improves precision in conductor crimping and connector assembly, enabling thinner conductor cross-sections and shorter stripping lengths to support lightweight, miniaturized vehicle wiring design.

2. Lower Total Cost of Ownership: Reduced factory floor occupation, fewer mechanical parts, simplified maintenance and fast format switching cut labor, workshop rental and changeover costs.

3. Full Compliance with Automotive Quality Standards: 100% online inspection and full product traceability supported by PC-based control meet strict automotive industry quality tracking regulations.

4. Sustainable Production Visibility: Built-in energy measurement modules quantify carbon emissions, helping wiring suppliers fulfill OEM carbon neutrality requirements.

Conclusion

As vehicle E/E architectures grow increasingly complex, flexible, compact and sustainable automation becomes the core competitiveness of wire harness manufacturers. Komax SLE’s Lambda X platform, powered by Beckhoff XTS magnetic conveying system and PC-based control, delivers a forward-looking solution for automated automotive wiring production. Independent mover control, modular mechanical design and integrated energy monitoring jointly address the pain points of traditional processing equipment, helping automotive suppliers boost productivity while realizing space-saving, low-carbon and high-flexibility manufacturing.
