Leuze Sensor DDLS 200 with 2 Mbit/s transmission rate

Description

Leuze Sensor DDLS 200 optical data transceiver from Leuze electronic transmits data from industrial networks via infrared light without contact or wear. Transmission is fast, deterministic and immune to interference. The method of function is absolutely transparent: This means that the optical data transceiver does not represent a participant on a given network, but rather handles data communication without intervening in the communication process. Thus, it functions as reliably and as simply as a copper cable.

The optical data transceivers are used primarily in plant engineering, especially in applications where industrial networks such as PROFIBUS, DeviceNet or Ethernet etc. are transmitted to system components which are moved. Examples include high-bay storage devices, gantry crane bridges or side-tracking skates.
The DDLS 200 supports all of the major international interfaces
Infrared data transmission protects the DDLS 200 from interference.
The fast transmission rates and enormous operating ranges of up to 500 m make the DDLS 200 an essential centrepiece in modern plant engineering.

Features

2 Mbit/s High-Speed Digital Interface: Features a fast, dedicated 2 Mbit/s synchronous serial interface (DDLS – Digital Data Transmission Leuze Sensor) for rapid and deterministic data exchange, minimizing latency in time-critical control loops.
Bidirectional Data Communication: Enables two-way communication between the sensor and a master controller (e.g., PLC), allowing not only for the transmission of measured values but also for remote configuration, parameterization, and command of the sensor.
Integrated Diagnostics & Status Monitoring: Transmits comprehensive device health data alongside process values, enabling predictive maintenance, rapid troubleshooting, and increased system availability through early fault detection.
Noise-Immune & Robust Communication: Utilizes a differential signal transmission (typically RS-485/422 physical layer), providing excellent immunity against electromagnetic interference (EMI) in harsh industrial environments.
Synchronized Operation: Supports precise synchronization with other devices on the network, which is crucial for coordinated multi-sensor applications like position synchronization or contour measurement.
Scalable System Integration: Allows the connection of multiple DDLS-compatible sensors (e.g., distance sensors, light curtains, scanners) on a single cable run, simplifying wiring and reducing installation costs.

Applications

High-Speed Positioning & Measurement: Used in robotics, pick-and-place systems, and CNC machinery where real-time, high-resolution position or distance feedback is required for closed-loop control.
Automated Material Handling & Logistics: Integration into conveyor systems, automated storage and retrieval systems (AS/RS), and packaging lines for precise object detection, dimensioning, and sorting control.
Printing & Converting Machinery: Provides synchronized registration control, web tension monitoring, and cut-to-length applications requiring fast and accurate sensor feedback.
Electronic Assembly & Semiconductor Manufacturing: Enables precise component placement, wafer handling, and quality inspection in cleanroom or ESD-sensitive environments with reliable data integrity.
Industrial Safety Systems: Integration into safety light curtains or laser scanners where fast, reliable transmission of safety-related signals (e.g., muting status, diagnostic information) is paramount.
