The Omron F3SJ-A1505P20 is a type-4 safety light curtain from the F3SJ-A series, designed for finger and hand detection with a 20mm detection capability. Its 1505mm protective height covers a wide access area, and the 15mm beam pitch across 100 beams means it catches a finger reaching into the hazard zone before contact occurs — this is finger-protection class per IEC 61496. The operating range spans 0.2m to 9.0m, giving you flexibility for guarding openings from short reach zones up to machine perimeters. It runs on 24VDC supply and carries an IP65 rating — dust-tight and protected against water jets, so it holds up in washdown environments typical of food processing or automotive assembly lines. Built-in blanking and muting functions let you configure the curtain to ignore fixed obstructions (like a machine frame) or automatically bypass during material pass-through, which saves wiring a separate bypass sensor.
There are no known PCN or obsolescence triggers on this code as of the latest lifecycle record.
Integration Notes
Mounting the F3SJ-A1505P20 requires aligning the emitter and receiver columns with the protective height centered on the hazard zone. The IP65 housing is sealed for washdown but needs the gland plate entry properly torqued to maintain the rating. The 24VDC supply must be from a safety-rated PELV source. The blanking and muting configuration is set via the controller or software — verify the controller model supports the feature set you need before committing the panel layout.
