The Leuze DDLS 508 200.4 L Optical Data Transmission Transceiver (Order Code: 50132930) is part of the premier DDLS 500 generation engineered by Leuze electronic (Germany). Designed to establish contact-free, wear-free wireless communication over extensive industrial distances, this system acts as a high-speed "virtual fiber-optic link." It completely eliminates the mechanical wear, costly downtime, and complex cable-drag chains (festoon/reeling cables) typically associated with moving machinery.

Operating via an eye-safe infrared laser light source with a 1° beam opening angle on transmission frequency F4, the unit maintains reliable bidirectional communication across distances from 100 mm up to 200,000 mm (0.1 m to 200 m). It delivers an uncompromised real-time data throughput of 100 Mbit/s. Featuring a transparent Ethernet architecture, it natively supports demanding industrial network protocols such as PROFINET (RT, IRT, Conformance Class B), PROFIsafe over PROFINET, EtherNet/IP, CIP Safety, and TCP/IP/UDP without protocol latency. The optical design is fully immune to ambient industrial lighting and reflective surfaces, and allows adjacent parallel light axes to operate side-by-side without optical cross-talk.

The defining highlight of the "L" model is its integrated laser alignment aid. This embedded alignment laser allows a single commissioning technician to rapidly and accurately aim the optical axis across long distances within minutes, drastically reducing installation labor and commissioning costs. The front interface features a dynamic multi-segment LED bar graph that displays real-time received signal strength, enabling proactive diagnostics against optical misalignment or front-lens contamination before any communication drop occurs.

Constructed for severe factory environments, the DDLS 508 200.4 L is enclosed in a rugged, die-cast metal housing weighing 1,422 g and certified to IP65 environmental ingress protection. It withstands operational temperatures from -5°C to +50°C and meets stringent EN 60068 standards for mechanical shock and vibration resistance. Equipped with standard industrial M12 metal connectors (5-pin A-coded for power; 4-pin D-coded for network bus), it is the industry standard communication bridge for automated high-bay warehouses (AS/RS), harbor container cranes, overhead monorail systems (EMS), and automotive manufacturing plants.
