Leuze DDLS

Technical Specifications: Light source infrared laser / infrared LED; working distance ranges from several meters up to 200 m; supply voltage 18‑30 VDC; support PROFIBUS‑DP, PROFINET, EtherNet/IP industrial Ethernet protocol; laser safety class 1; M12 industrial connectors; operating temperature ‑20 °C to +60 °C; integrated alignment auxiliary function; built‑in heater for low‑temperature condensation prevention for partial models.

Functional Features: Bidirectional high‑speed real‑time optical data transmission; laser‑assisted alignment auxiliary function; anti‑reflection‑surface interference capability; built‑in heating module for cold‑condensation prevention; support multiple mainstream industrial bus protocols; status LED diagnosis indicator; digital input/output signal channel; laser class 1 safe for personnel eyes.

Application Scenarios: Automated high‑bay warehouse stacker cranes, moving gantry equipment, building‑to‑building short‑distance wireless industrial communication, rotating machinery data transmission, occasions where cable dragging cannot be used for moving automation equipment.

Performance Parameters: Real‑time industrial‑grade communication cycle; stable transmission under fog and light‑interference environment with line‑of‑sight guarantee; comply with international laser safety standard EN 60825.

Material Composition: Die‑cast aluminum alloy housing; optical lens assembly; infrared laser / LED light‑emitting component; industrial communication PCB; M12 shielded metal connectors.

Structural Features: Metal housing with mounting bracket for wall‑and‑panel installation; front‑side optical transmitting‑receiving lens window; front‑panel status indicator lamps; M12 power‑and‑bus connectors on side surface; adjustable mechanical installation bracket for optical‑path alignment.

Working Principle: Convert electrical industrial‑bus signal into modulated infrared optical signal and emit it; opposite‑end device receives infrared optical signal and restore it into electrical bus signal, realize bidirectional transparent data transmission between two devices, complete industrial bus real‑time communication via optical path.

Installation Requirements: Two DDLS devices must keep direct unobstructed line‑of‑sight optical path; fix installation bracket firmly; adjust optical‑path alignment with built‑in auxiliary laser; install inside non‑condensing environment, use heater option for cold‑humid outdoor environment; reliable protective ground connection.

Usage Notes: Must ensure no obstacles block optical path during operation; belong to laser class 1 device, do not stare at optical‑window for long‑time close observation; avoid severe vibration impact on optical‑lens assembly; lens surface must be kept clean; do not use if lens is scratched or damaged; verify bus protocol configuration matches system requirements.
