The XUSL4E30H061N: Type 4 per IEC 61496-1 means it can detect a 30 mm object (finger or small hand) reaching into the hazard zone — the resolution sets the minimum object size that triggers the safety output.
Deployment context — guarding a hazard zone
This light curtain mounts between the emitter and receiver columns, typically guarding a machine access point or robot cell. The 610 mm protected height covers a mid-sized opening; 30 mm resolution catches fingers reaching past the detection plane. The Type 4 SIL 3 / PL e rating means the safety output is reliable enough for the highest-risk guarding applications without a separate safety relay in the loop.
