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.

Frequently asked questions
What does the 20 mm detection capability mean for guarding?
The 20 mm detection capability means the light curtain can detect a 20 mm diameter object — typically a finger — entering the protected field. This is finger-protection class per IEC 61496, used where an operator can reach into the hazard zone and the machine must stop before a finger contacts the danger point.
What is the protective height and beam count?
The protective height is 695 mm, formed by 46 beams at a 15 mm pitch. This height covers a single-station access opening; for taller openings, multiple curtains are stacked.
Can this light curtain be used in washdown environments?
Yes. The IP65 rating means the housing is dust-tight and protected against water jets from any direction, making it suitable for food-and-beverage or packaging lines where hose-down cleaning is routine.
