The Leuze BPS 348i SM 100 D Bar Code Positioning System (Part Number: 50124982) belongs to the flagship BPS 300i generation developed by Leuze electronic (Germany). As a premier industrial optical solution, it is engineered to deliver highly accurate, contactless, and absolute position measurement along linear and curved trajectories for automated warehouse stacker cranes, overhead conveyors, and mobile robot platforms.

Operating via a red laser light source (Laser Class 1, eye-safe conforming to IEC 60825-1:2014), the system features a lateral light beam exit (SM configuration) designed to continuously scan industrial barcode tape fixed along the mechanical travel axis. With an expansive working depth of field from 50 mm to 170 mm and an extensive measurement range spanning from 0 up to 10,000,000 mm (10 km continuous travel), it provides uninterrupted absolute positioning without mechanical wear. The unit boasts an ultra-fine reproducibility of 0.05 mm (1 sigma) and a 2 ms rapid measurement output cycle, ensuring that position feedback remains strictly real-time and error-free even when vehicles operate at extreme speeds up to 10 m/s.

Constructed for harsh factory environments, the BPS 348i SM 100 D is housed in a rugged die-cast metal enclosure with a scratch-resistant glass optical window and rated to IP65 ingress protection. The instrument offers industrial reliability with an outstanding Mean Time to Failure (MTTF) of 83 years. The "D" model designation indicates an integrated monochromatic graphic display (128 x 32 pixels) paired with diagnostic LEDs, enabling commissioning technicians to monitor real-time millimeter coordinates, evaluate barcode reading quality, and calibrate parameters directly on-site without requiring external programming equipment.

For seamless network integration, the BPS 348i integrates a high-performance PROFINET RT process interface with embedded dual-port Ethernet switch capability, enabling easy daisy-chain topology directly to industrial PLCs. A dedicated USB port is also available for rapid offline service and configuration via GSDML modules. It is the definitive positioning standard for automated high-bay warehouses (AS/RS), automotive body-in-white transfer lines, overhead electric monorails (EMS), and smart factory autonomous mobile robots (AGVs/AMRs).
