Code reading without compromise
The new DCR 100i series code reader from Leuze reliably captures 1D and 2D bar codes and provides an adjustable focus for a flexible working distance within the reading field.
Owen, December 5, 2025 – Whether on printed circuit boards, assemblies, or moving packaging, tracking and quality control in industrial production require sensors that can reliably detect bar codes. This is where the new DCR 100i series code reader from Leuze comes in: It provides precise reading of 1D and 2D codes through its high-resolution 1.3-megapixel CMOS imager. Users also benefit from simple commissioning and intuitive software.
Precision across the board
Leuze's Sensor People have equipped the DCR 100i code reader with powerful decoding algorithms and flexible focus areas. The sensor thus reliably detects even small 1D and 2D bar codes from different distances. With a frame rate of 120 frames per second, the DCR 100i captures even fast-moving objects – ideal for systems with high process speeds of up to two meters per second. DPM codes applied directly to components are also detected. This is particularly important in the electronics industry. Another advantage: The DCR 100i’s large field of view allows it to read multiple codes simultaneously. This allows it to identify complex or grouped packaging efficiently.
Exact focus
System operators can flexibly adapt the DCR 100i to different working distances, code sizes and surfaces using the manually adjustable focus. Four selectable focus ranges – from very short (40 mm) to a long operating range (550 mm) – enable sharp images and high read rates in any application. This gives system operators maximum flexibility for various industrial application scenarios.
Integrated in no time
Users can conveniently set up the code reader directly on the device: Integrated trigger and teach buttons as well as automatic adjustment of exposure, illumination and decoding allow fast and error-free commissioning without requiring a PC. The DCR 100i series provides Ethernet connectivity and supports industrial protocols such as Modbus and TCP/IP, as well as the RS232 serial interface. This allows the device to be integrated seamlessly into different automation systems.
Robust design
The DCR 100i also stands out for its compact and robust design: The sturdy aluminum housing with protection class IP64 reliably protects the device from dust and splash water. A glass cover provides lasting protection for the optics. With its space-saving dimensions (44 x 53 x 29 millimeters), the code reader is easy to integrate into industrial environments.
