The Omron F3SJ-A1955P20 is a safety light curtain from the F3SJ-A series, built for finger and hand protection with a 20 mm detection capability. That 20 mm detection means it catches fingers reaching into the hazard zone (finger-protection class per IEC 61496-1). The 1955 mm protective height covers a wide vertical opening, and the 130 beams at 15 mm pitch give it a 0.2 m to 7.0 m operating range. It runs on 24 VDC and is rated IP65 for dust-tight, water-resistant duty — suitable for washdown environments in food-and-bev or packaging lines.
Integration Notes
The light curtain includes blanking and muting functions, which let it ignore fixed obstructions (like a conveyor frame) and temporarily bypass during a material pass-through. That's a practical feature for automated assembly or palletizing cells where you need the guard to stay on but not trip on every cycle. The IP65 rating means the sensor body and optics withstand washdown — suitable for food-and-bev lines. Operating temperature range is -10°C to 55°C.
