Description
Core Product Summary
The Leuze DDLS 200/200.2-60 is an optical data transmission transceiver designed for non-contact, point-to-point wireless communication in automated industrial environments. Operating over an infrared light beam, the module enables transparent data transfer without physical cable wear or trailing cable assemblies. It is primarily deployed on automated guided vehicles (AGVs), rail-guided gantry cranes, stacker cranes, and transfer cars where mechanical cable carriers are impractical or prone to fatigue.
This model supports a working range from 200 mm up to 200,000 mm (200 m) and operates on transmission frequency F2. It provides real-time data transmission at speeds up to 2 Mbit/s for optical signals while interfacing with standard industrial Ethernet protocols (TCP/IP, UDP). Featuring integrated optical alignment displays, an IP65 metal enclosure, and immunity to ambient light interference, the unit maintains stable point-to-point communication across moving machinery axes.

Detailed Product Overview
The Leuze DDLS 200/200.2-60 establishes a contact-free, optical communication link across moving system components where hardwired connections suffer from mechanical stress or flexural fatigue. In automated material handling setups, stacker cranes and transfer carriages move continuously along fixed tracks; replacing festoon cables or drag chains with optical data transmission eliminates mechanical wear points and increases communication reliability.
The DDLS 200 series uses modulated infrared light to create an interference-free transmission path that remains immune to ambient lighting and reflective background surfaces. Data handling is protocol-transparent, allowing Ethernet frame transfer (TCP/IP, UDP) between the moving device and stationary control cabinets without altering the network payload.
The transceiver includes built-in signal diagnostics displayed directly on the unit via an integrated LED bargraph. This visual feedback simplifies mechanical alignment during commissioning and provides continuous signal margin monitoring. An integrated digital switching output can trigger a pre-failure warning signal if optical path attenuation occurs due to dirt buildup on the optics or structural misalignment, allowing maintenance prior to communication interruption.
