AREX400 AF is the newest laser marker by DATALOGIC that breaks free from the constraints of traditional fixed-focus laser markers. AREX400 AF introduces software-controlled Adjustable Focus technology embedded in the scanhead, enabling simpler setup, faster job changeover and reliable marking on multi-surface parts. This translates into higher throughput, lower reconfiguration costs and consistent quality across every marked piece.

The AREX400 AF laser marker sets a new benchmark for high-performance industrial marking. Compact yet robust, it is engineered to excel in the most demanding  environments in industries such as Automotive, Electronics, Machine Tools and Precision Mechanics.

In modern Direct Part Marking (DPM) applications, readability and durability are essential. AREX400 AF ensures that crucial data are permanently marked directly onto your components, thus eliminating the risk of lost or damaged labels and guaranteeing consistent traceability throughout your product's lifecycle.

Most real-world marking applications don't require full 3D capability, yet many marking systems are over-engineered as if they did. The AREX400 AF showcases a more pragmatic approach: as a 2.5D laser marking solution, it efficiently handles both flat and multi-level workpieces.
It avoids unnecessary cost and complexity while enabling flexible marking at different heights.

Unlike traditional fixed-focus systems, focus distance can be adjusted instantly via LIGHTER™ 9 software, allowing quick adaptation to different parts, reducing setup time, and ensuring smoother, more efficient production.

With an optional accessory micrometric Distance Sensor connected to the scanhead, AREX400 AF can dynamically adjust the focus to compensate parts height fluctuations or positioning errors, thus ensuring consistent marking quality and zero scraps.

The AREX400 AF marks complex components with multiple surfaces or height levels in a single cycle, without external motorized Z-axes or dedicated fixtures. By removing mechanical adjustments and costly additional hardware, it ensures flawless marking across diverse assemblies with minimal setup and easy machine integration.

Its streamlined design minimizes commissioning effort, delivering an unparalleled price-to-performance ratio, lower integration costs, and reduced total cost of ownership.

This combination of versatility, simplicity, and efficiency makes the AREX400 AF a breakthrough for manufacturers seeking fast return on investment without compromising marking quality or reliability.

Modern agile manufacturing require fast adaptation to changing parts, formats and batch sizes. AREX400 AF is designed to handle format changes effortlessly using software-controlled Z positioning and automatic focus adjustment that eliminate manual reconfigurations.

The benefits are seamless transitions, minimal downtime and consistent marking quality. When a line switches to new products or part dimensions change, AREX400 AF will adapt in a flash.

AREX400 AF is ideal in industrial scenarios where production demands change often and there is extensive parts variability. Switch instantly to new product requirements, from batch-of-one to mass production, with minimum reconfiguration costs.

The AREX400 AF is built for dynamic marking integration where flexibility truly matters. Thanks to market-unique robotic‑grade cabling and a lightweight scanhead, the system unlocks marking on-the-move within robot cells.

This delivers hassle‑free installation on low-payload robots and reliable performance in continuous‑motion environments, breaking free from the common limitations of static setups.

Production lines are increasingly becoming denser, and space-saving is crucial. AREX400 AF features the market’s most compact Adjustable-Focus scanhead, designed to fit where traditional laser markers can’t, while delivering full IP64 environmental protection.

The AREX400 AF fits seamlessly into high-density automated lines and tight robotic cells, with IP64 protection covering the entire scanhead, including the lens and conduit. This ensures reliable operation in dusty, harsh industrial environments while reduced maintenance requirements extend service intervals. 

AREX400 AF's fully electronic Safe Laser Off (SLO) module offers failsafe laser beam shutdown, without the typical wear of traditional contactors or electromechanical shutters that require periodic replacement.

This TÜV-certified redundant module provides best-in-class safety protection regardless of the number of switching operations, allowing the achievement of Performance Level PLe in ISO 13849-1 compliant integrations.
