Industrial Applications

1. Automated Guided Vehicle (AGV) Communication in Warehouses

Provides reliable, high-speed Ethernet communication between a stationary control system and an AGV moving within a large warehouse. The 0-150m detection range and 100 Mbit/s data rate are ideal for real-time control and data exchange (e.g., inventory updates, navigation commands) for AGVs traversing aisles.

Problem Solved

Overcomes the limitations of physical cables or unreliable wireless solutions in dynamic environments, ensuring continuous, high-bandwidth data flow for mobile robotics using its 150m range and 100 Mbit/s data rate.

2. Stacker Crane Data Transfer in High-Bay Storage Systems

Facilitates robust Ethernet communication for stacker cranes, allowing them to exchange position data, order information, and diagnostic messages with the Warehouse Management System (WMS) as they move vertically and horizontally in high-bay racks. The 150m range is suitable for many such systems, and its IP65 rating protects against dust.

Problem Solved

Ensures uninterrupted data flow for precise crane movements and efficient material handling, even when spanning significant distances and operating in dusty industrial environments, thanks to its 150m range and IP65 protection.

3. Cross-Docking Conveyor System Synchronization

Enables seamless Ethernet data exchange between different sections of a large, modular conveyor system in a cross-docking facility, where sections may need to communicate across gaps or movable bridges for precise package routing and sorting. The 100 Mbit/s speed allows for quick decisions and synchronization of multiple conveyor segments.

Problem Solved

Eliminates the need for complex slip rings or drag chains for power and data on moving or separated conveyor segments, providing flexible and maintenance-free high-speed 100 Mbit/s data links for distributed control.
