What the key ratings mean for fit
The F3SJ-A0695P20 is an Omron F3SJ-A series safety light curtain with a 20 mm detection capability — finger-protection class per IEC 61496-1/2, meaning it catches individual fingers reaching into the hazard zone, not just a whole hand. The 15 mm beam pitch and 46 beams create a 695 mm protective height, sized for guarding a single-station access opening on a machine cell. Operating range spans 0.2 m to 9.0 m, so it works across short reach-in zones up to full machine perimeter distances. Rated IP65 — dust-tight and protected against water jets — which suits washdown environments in food-and-beverage or packaging lines where the sensor body and optics must withstand hose-down cleaning without sealing failures. Blanking and muting functions are built in, so the curtain can ignore fixed obstructions (blanking) or be overridden during a material pass-through cycle (muting) without external controller logic. Supply is 24 VDC, standard for safety circuit power in industrial control panels. Operating temperature range of -10°C to 55°C covers most indoor production floor conditions but not freezer or outdoor environments.
