SR-1 vs Light Curtains

Light Curtains: Advanced Safety Barrier with Multiple Infrared Beams.

Light curtains solve a specific problem: guarding a known opening. They work best when you can define where people enter, keep the cell geometry stable, and maintain a clean line of sight.

That breaks down in modern production:

• People enter from multiple directions.

• Pallets, carts, and tooling change the environment.

• Maintenance requires flexible access.

• Safety becomes a patchwork of curtains, gates, interlocks, and exceptions.

  
  

Light curtains protect a line. Real work happens in 3D.

SR-1 uses redundant 3D sensing to detect people in the active area, not just at an entry point. This lets you protect the workspace as it exists, even as the cell evolves. You can support flexible access while controlling safe behavior, reduced speed or stop all based on your risk assessment and system design.

Common reasons plants outgrow curtains:

• More than one access route

• Frequent changeovers that force retuning

• Need for shared space (people and robots)

• Hard-to-guard areas that become “workarounds”

  
  

What SR-1 changes:

• You stop treating safety like a doorway problem

• You base safety behavior on the live environment

• You can reduce nuisance stops caused by rigid entry guarding

  
  

If your cell keeps evolving, your safety should handle change without constant rebuild.
