Leuze Introduces New Code Reader Series for Fast and Accurate Scanning
Leuze’s DCR 100i series code reader combines adjustable focus, high-speed imaging, and a compact industrial design to deliver reliable 1D and 2D code reading in demanding production settings.
Modern production depends heavily on traceable parts. A tiny 2D mark on an electronic component or a printed label moving down a packaging line serves the same purpose; it allows manufacturers to confirm where an item came from and where it is going. This information plays a crucial role in quality control.
Leuze has introduced its new DCR 100i series code reader to meet modern production demands, combining a high-resolution 1.3-megapixel CMOS imager with an adjustable-focus optical system engineered for flexible working distances. The result is a compact reader that delivers consistent, accurate decoding in environments where small codes, shifting surfaces, and rapid motion typically challenge vision systems.

DCR 100i Series Code Readers
At the heart of the DCR 100i series code reader is a global-shutter CMOS sensor paired with robust decoding algorithms; an architecture designed to extract clean, accurate reads even when codes are small, worn, or positioned unpredictably. Its 120 frames-per-second capture rate keeps pace with processes running at up to 2 m per second, allowing the device to read bar codes on moving packaging reliably.
Direct part mark (DPM) codes are particularly tough codes to capture, especially in electronics manufacturing, where they’re etched directly onto metal or uneven surfaces. The DCR 100i is built to read those marks cleanly. It also has enough horizontal coverage to take in more than one code at a time, which is useful when products carry both a 1D and 2D label or when several items pass through the scan area together.
Flexible Focus, Simple Setup
A defining feature of the new series is its manually adjustable focus, which lets operators tailor the device to code size, distance, and material without swapping hardware. Four selectable focus regions span 40 mm to 550 mm, accommodating everything from ultra-dense microcodes on semiconductor components to broader markings on assembled packaging.

Furthermore, Leuze has designed its code reader to be easy to set up. The unit includes its own trigger and teach controls, so operators can dial in exposure, lighting, and decoding settings right on the hardware instead of going through a computer. It also offers an automatic mode that fine-tunes those adjustments on the fly, a practical advantage in plants where code quality changes from batch to batch or where lighting conditions aren’t always consistent.
Connectivity options include Ethernet with TCP/IP and Modbus TCP support, plus RS232 for legacy compatibility. Two switching outputs (good read/no read) and a trigger input round out the interface package, allowing the reader to fit into both new and established automation architectures cleanly.
Built To Withstand Industrial Environments
Despite its compact footprint (just 44 x 53 x 29 mm), the DCR 100i is built for durability. The housing is made of aluminum and designed to hold up under tough conditions. Its IP64 rating protects the internal components from dust and splashing water, and the glass cover keeps the optics safe from wear and debris. Because the device is small and easy to position, it can be installed in tight spaces, from robotic mounts to narrow areas along busy conveyor lines.

In electronics production, the DCR 100i’s DPM reading capabilities and fine-focus modes allow it to read intricate codes on ICs and PCB assemblies with the precision required for traceability workflows. For packaging environments, the device’s fast frame capture and optimized illumination enable accurate reads on boxes moving at conveyor speeds up to 2 m/s. Its ability to decode multiple codes simultaneously offers greater efficiency for grouped packaging lines that require validating both 1D and 2D marks.
High-Resolution Performance for Modern Production Lines
Leuze has developed the DCR 100i series for manufacturers who need reliable decoding without the complexity that normally comes with vision systems. The DCR 100i brings several practical strengths together, including an adjustable focus, fast image capture, and straightforward setup work alongside a rugged housing built for demanding environments. This combination gives operators a reader they can place in almost any part of the line where dependable code capture is essential.
As manufacturers push for clearer traceability and higher throughput, the need for compact and reliable identification tools continues to grow. The DCR 100i fits into that movement by offering a small footprint and the flexibility required for production systems that are expected to handle the next generation of output.
