The Leuze AMS 348i 200 Optical Distance Sensor (Part No: 50113711) belongs to the world-renowned AMS 300i generation developed by Leuze electronic (Germany). Engineered specifically for demanding high-bay warehouse operations and industrial material handling, this high-precision optical distance sensor provides dependable non-contact positioning and collision avoidance over long distances with millimeter precision.

Operating on advanced Time-of-Flight optical principles combined with high-frequency modulated red laser light at 655 nm (Laser Class 2, compliant with IEC/EN 60825-1:2014), the AMS 348i 200 measures distances ranging smoothly from 200 mm up to 200,000 mm (0.2 m to 200 m). The sensor delivers an absolute measurement accuracy of ±3 mm and a reproducibility (3 sigma) of 2.1 mm. With an ultra-fast measurement output cycle of just 1.7 ms and a processing calculation time of 8 ms, the unit maintains high-accuracy position updates even when targets traverse at extreme mechanical travel speeds of up to 10 m/s.

From a hardware and reliability perspective, the AMS 348i 200 is built with a rugged diecast zinc/aluminum housing and scratch-resistant optical glass window, rated to IP65 environmental ingress protection. It features an impressive Mean Time to Failure (MTTF) of 31 years, ensuring dependable 24/7 industrial service. The sensor integrates a high-contrast multi-line LC display, four status LEDs, and an ergonomic membrane keypad, allowing commissioning technicians to verify signal reception quality, diagnose bus status, and fine-tune operational parameters directly on-site without requiring external programming laptops.

The primary system-integration feature of the AMS 348i 200 is its integrated PROFINET RT interface (Conformance Class B, 100 Mbit/s) with embedded dual-port Ethernet switch functionality (BUS IN / BUS OUT on standard M12 D-coded connectors). This allows seamless daisy-chain or ring network topologies without requiring external industrial switches, significantly lowering wiring expenses and system complexity. Position and velocity parameters are streamed cyclically in real-time to central PLC systems, making it the premier choice for gantry cranes, overhead hoists, automated AS/RS stacker systems, and high-speed automotive skillet transfer conveyors.
