Its 4 infrared beams create a 910mm protective height, covering a 0 to 12.0m operating range — sized for guarding access to a machine hazard zone like a press brake or robotic cell perimeter. Rated IP65/IP67, the body withstands washdown and outdoor exposure, so it's suited for food processing lines or automated assembly stations where hosing down the cell is part of the cleaning cycle.
Type 4 per IEC 61496-1 means this is the highest safety integrity level for electro-sensitive protective equipment — it can detect a finger or hand reaching into the hazard zone and trigger a stop signal within the safety-rated response time. The 4-beam array is a body-detection pattern, not a finger or hand detection grid; it catches a torso or limb crossing the plane, so it's appropriate for perimeter guarding where fine resolution isn't needed. The 910mm protective height covers the vertical span from roughly knee to shoulder for a standing operator. Paired with the 12m maximum range, this curtain can guard a large machine opening from a single emitter-receiver pair mounted at the far end of the cell. Runs on 24VDC supply, standard for safety circuits in most industrial control panels.
