The Leuze AMS 348i 200 Optical Distance Sensor (Part Number: 50113711) is an advanced laser measurement and positioning instrument from the flagship AMS 300i Series engineered and manufactured by Leuze electronic (Germany). Designed specifically for dynamic absolute positioning tasks and millimeter-accurate distance measurement over an expansive envelope from 200 mm to 200,000 mm (0.2 to 200 meters), this high-performance sensor meets the highest reliability benchmarks of modern intralogistics, automated warehousing, and intelligent manufacturing plants.

At the core of the AMS 348i 200 is Leuze's proven optical phase-comparison measurement technology utilizing a high-visibility red laser transmitter (655 nm wavelength, Laser Class 2 eye-safe compliance). Empowered by advanced internal digital signal processing algorithms, the sensor achieves an impressive absolute measurement accuracy of ±3 mm and a reproducibility (3 sigma) of 2.1 mm across the full 200-meter operating span. In addition, the instrument delivers a rapid measurement update rate of 1.7 milliseconds and accommodates target traversal speeds of up to 10 m/s (36 km/h). This enables host PLCs to execute closed-loop motion control in real-time, eliminating overshoot and oscillation when automated stacker cranes accelerate and brake during high-throughput warehousing cycles.

A premier technical hallmark of the AMS 348i model is its integrated industrial PROFINET RT communication interface (Conformance Class B) featuring dual-port M12 D-coded connectors (BUS IN and BUS OUT) with embedded line-switch functionality. This allows seamless daisy-chain or ring network topology integration directly onto factory automation fieldbuses without requiring external network switches, drastically cutting hardware deployment costs and streamlining cable runs. Device configuration, diagnostics, and parameter assignment are effortlessly executed via standardized GSDML device description files in engineering environments such as Siemens TIA Portal, or locally via the integrated backlit LC Display and tactile membrane keypad.

The instrument is encapsulated in a rugged, monolithic diecast zinc and aluminum alloy enclosure weighing 2.45 kg, fitted with a scratch-resistant optical glass lens aperture, and sealed to an IP65 ingress protection rating. This robust mechanical packaging ensures complete immunity against industrial shock, high-vibration gantry crane travel, and airborne industrial particulate contamination, delivering an exceptional Mean Time To Failure (MTTF) of 31 years for uninterrupted 24/7 industrial service.
