A 50 Watt fiber laser marking source uses a high-power pulsed fiber laser (wavelength ~1,064 nm) to deliver intense, rapid laser pulses that interact with the material surface to create permanent marks. In the cab XENO 4 variant, the beam source is housed in a control unit (19″ rack) and connected via fiber to a compact galvanometric scan head, enabling flexible positioning and minimal footprint.  The high beam quality (M² < 1.8) and pulse peak powers ensure sharp, deep marks even on hardened metals or coated components. The system supports marking fields ranging from 69×69 mm to 290×290 mm depending on the lens used. Typical features include an integrated focus-finder, shift of focus up to ±70 mm (in the S-variant) and full TCP/IP connectivity for Industry 4.0 integration.  The 50 W output class ensures faster marking and deeper or higher-contrast marks compared with lower-power models, making it ideal for industrial throughput applications.

The 50 Watt Fiber Laser Marking Source delivers a powerful combination of high-performance laser, agile scanning and industrial-grade integration features designed for manufacturing scale.

High‐Power Fiber Laser Source:

With 50 W of continuous wave (cw) output in a pulsed format, the laser provides substantial energy for rapid marking of metals, plastics and coated surfaces. According to cab, the beam source in the XENO 4 series is diode-pumped and air-cooled, paired with high pulse peak powers for optimum mark quality.  The high beam quality (M² < 1.8) ensures tight focusing and excellent resolution—even when covering larger mark fields. 

Flexible Marking Fields & Optics:

Different plano-spherical lenses enable mark fields from 69×69 mm up to 290×290 mm.  Smaller fields produce finer details (e.g., ~25 μm spot diameter), while larger fields cater to bigger components or multiple mark zones in one go. Example: the F-Theta 100.2 lens gives 69×69 mm field (~25 μm spot) and the F-Theta 420.2 lens provides 290×290 mm field (~85 μm spot). 

Compact, Modular Build & Automation-Ready:

The source and control unit combine in a 19″ rack, while the galvanometer scan head is mounted remotely via fiber. This modular form allows flexible integration in OEM systems or factory cells.  With height-shift capability up to ±70 mm (in XENO 4S version) and an integrated focus-finder, the system accommodates components with variable topography with minimal cycle time penalty.  TTL and Ethernet / TCP/IP connections allow full MES/PLC integration, aligning with Industry 4.0 demands. 

Material Versatility and Mark Quality:

The system supports permanent marking on various materials—stainless steel, aluminium, brass, painted/coated metals and engineering plastics. The 50 W class enables deeper annealing marks or faster throughput compared to 20–30 W alternatives, making it ideal for high-volume production scenarios. The non-contact nature of the process ensures minimal tool wear and no consumables.

Reliability & Serviceability:

Air-cooled architecture reduces maintenance. The compact scan head (≈3-4 kg) and stable mechanics minimise downtime. From the catalog: control unit power consumption up to ~350 W for the 50 W version. 

In sum: the 50 W Fiber Laser Marking Source combines performance (output power and optics), flexibility (field sizes, focus shift), integration (modular, IoT ready) and durability (industrial-grade design). It is tailored to high-throughput marking of industrial components requiring precision, speed and reliability.

Automotive & EV Manufacturing

In automotive and electric vehicle production, the cab XENO 4 Laser Marking System is widely used for VIN plates, engine and gearbox identification, battery pack labels, and traceability codes. The permanent laser marks withstand heat, oil, vibration, and long operational lifecycles, making them ideal for safety-critical and compliance-driven applications.

Electronics & Electrical Industry

Electronics manufacturers use XENO 4 for PCB identification, enclosure labels, QR codes, serial numbers, and component traceability. The non-contact laser marking process ensures high precision without damaging sensitive electronic components or insulation materials.

Industrial Machinery & Equipment

For industrial machinery manufacturers, XENO 4 produces durable name plates, asset tags, safety labels, and specification plates. These markings remain legible in harsh environments involving dust, chemicals, and mechanical wear, supporting asset tracking and regulatory compliance.

Medical Devices & Instruments

In medical manufacturing, the system is used to mark surgical instruments, tools, and medical devices with sterilisation-resistant serial numbers and UDI-compliant codes. High precision and repeatability ensure compliance with stringent healthcare regulations.

Aerospace, Defence & Heavy Engineering

Aerospace and defence industries rely on XENO 4 for permanent marking on alloys and critical components where long-term legibility is mandatory. The system supports traceability, quality control, and compliance with international standards.

Consumer Goods, Tools & Packaging

XENO 4 is also used in consumer goods, appliances, tooling, and packaging industries for branding, batch numbers, and compliance markings. Its flexibility makes it suitable for both batch production and fully automated manufacturing lines.
