The Omron F3SJ-A2495P30 is a type-4 safety light curtain from the F3SJ-A series, rated for hand/arm detection with a 30mm detection capability. That 30mm resolution means it catches a hand or forearm reaching into a hazard zone — it's sized for point-of-operation guarding, not whole-body presence sensing. The 2495mm protective height covers a tall access area, and the 200 beams at 25mm pitch give continuous coverage across that span. Operating range runs 0.2m to 7.0m, so it fits both tight machine openings and wider conveyor access points. Rated IP65 — dust-tight and protected against water jets — so it holds up on washdown lines or in dusty assembly cells. Powered at 24VDC, standard for safety circuits; the built-in blanking and muting functions let it ignore fixed obstructions (like a fixture) or suppress during a material pass cycle without tripping the safety relay.
For a safety light curtain guarding a production line, that means the manufacturer still supports it — no last-time-buy clock ticking. No official successor has been issued, so this order code remains the direct fit for any BOM that calls out the F3SJ-A2495P30.
Panel and machine integration
Mounts via the standard F3SJ-A bracket set; the 2495mm column needs a rigid extrusion or two-point support to keep alignment stable over the 7m range. The IP65-rated housing handles washdown, but the cable entry and M12 connector (if used) should be oriented downward to avoid pooling. Power draw is minimal at 24VDC — a standard safety power supply handles it — but the muting and blanking inputs need to be wired per the system's safety logic, typically through a safety PLC or a dedicated safety relay module. The 200-beam array means the controller must process a full scan; verify the cycle time of the safety CPU if the curtain is used in a high-speed stop category.
