Its 55 mm detection capability means it reliably detects a human leg or torso entering the guarded area, which is the standard for body protection per IEC 61496 — not finger or hand detection. The 20 beams at a 50 mm pitch create a protective height of 970 mm, covering the lower body zone up to about hip height on an average adult. Operating range spans 0.2 m to 9.0 m, so it works across a typical machine opening or conveyor aisle without needing a separate long-range variant. Supply is 24 VDC, standard for safety circuits in industrial control panels.
Built-in blanking and muting functions allow the curtain to ignore fixed obstructions (like a machine frame) or temporarily suspend detection during a workpiece pass-through. These are programmable features that reduce false trips without external bypass modules.
