Belden, in collaboration with Accenture and NVIDIA, is demonstrating that the true potential of "Physical AI" in manufacturing—such as virtual safety fences—is unlocked only by Time-Sensitive Networking (TSN). This high-speed, deterministic network infrastructure provides the microsecond-level synchronization and closed-loop control necessary for AI to perceive hazards and trigger real-time safety responses, moving factories beyond rigid physical cages.
