The Omron F3SJ-A1460P25-TS is a Type 4 safety light curtain from the F3SJ-A series, designed for hand detection at machine access points. Its 25mm detection capability means it catches a hand or finger reaching into a hazard zone — the 20mm beam pitch and 73 beams create a protective curtain 1460mm tall. That height suits it for guarding vertical openings on assembly stations, packaging machines, or press brakes where the operator needs to reach in but the machine must stop before fingers enter the danger area. Operating range spans 0.2m to 9.0m, so it works both in tight reach-in applications and across wider machine openings. The 24VDC supply is standard for safety circuits; plan for a dedicated safety-rated power source, not a shared 24V bus that could drop under load.
Hand protection (25mm detection) is the key spec: it meets the finger-protection class per IEC 61496-1, but note it's not finger-safe — that would require a 14mm or finer resolution. If your risk assessment calls for finger detection, step up to the 14mm variant in the same F3SJ-A family. The 20mm beam pitch gives you 73 beams across 1460mm, which is a good match for guarding a standard operator station opening. IP65 rating means the emitter and receiver housings withstand washdown splashing and dust — suitable for food processing or packaging lines where hoses are used, but not for submersion or high-pressure spray (that's IP67 or IP69K territory). The blanking and muting function lets you program fixed or floating blanking zones (for a workpiece passing through) and muting sensors for automatic material feed — this is what the -TS suffix indicates, a model with these advanced features enabled.
Integration notes
Mounts with standard brackets (sold separately); alignment aids and a built-in alignment tool simplify setup. The 24VDC supply powers both emitter and receiver; check the current draw against your safety relay or controller's output capacity. The muting and blanking functions require external muting sensors wired into the control logic — plan for two muting sensors per zone if you're using automatic feed. The IP65 housing means you can mount it in washdown zones without an extra enclosure, but keep the connector ports oriented downward to prevent water pooling.
