Example Safety System Combinations

Real-world configurations using Omron Safety Components

Use Case 1 – Robotic Cell with Hazardous Motion (Pick & Place / Assembly)

A compact robot cell with hazardous moving parts where operators frequently enter for adjustments, tooling changes, and cleaning.

Recommended Device Combination:

  • D40A-2 Non-contact Door Switch: Detects door status reliably even when alignment is imperfect.
  • D4SL-N Guard Lock: Keeps the gate locked until the robot arm reaches a safe stop state.
  • F3SG-SR Light Curtain: Adds a secondary protective boundary at openings or part-feeding areas.
  • A22E Emergency Stop: Mounted on the robot cell frame for immediate access.
  • G7SA Relay (compact): Suitable for single-cell safety implementations.

Key Benefits:

  • Non-contact detection reduces mechanical wear and maintenance.
  • Guard lock ensures safe stop before gate opening.
  • Light curtain provides additional protection without blocking visibility.
  • Ideal for small automated cells and retrofits.

Use Case 2 – Conveyor Line with Long Travel Zones

Long-distance conveyor systems where operators walk alongside equipment, requiring “stop from anywhere” functionality.

Recommended Device Combination:

  • ER6022 Rope Pull Switch: Allows operators to trigger an emergency stop from any point up to 200 m.
  • F3SG-SR Light Curtain: Secures loading/unloading zones or transfer points.
  • A22NE-P Emergency Stop: Installed at fixed inspection or operator stations.
  • G9SE Safety Relay: Handles safety inputs with simple wiring and LED diagnostics.

Key Benefits:

  • Rope pull provides comprehensive, intuitive emergency-stop coverage.
  • Light curtain prevents entry into hazardous automatic-transfer zones.
  • Compact safety relay simplifies troubleshooting and minimizes downtime.
