The F3SJ-A1025P20 is a Type 4 safety light curtain from Omron's F3SJ-A series, designed for finger and hand protection on access and hazard-point guarding applications. The 20 mm detection capability and 15 mm beam pitch mean it catches fingers reaching into the danger zone — meeting finger-protection class per IEC 61496-1. With 68 beams over a 1025 mm protective height, it covers a single machine opening or a conveyor infeed up to about a meter wide. Operating range spans 0.2 m to 9.0 m, so it works for both tight machine guarding and longer access paths. The 24 VDC supply is standard for safety circuits. IP65 rating means the housing and optics withstand washdown — suitable for food-and-bev or wet machining lines.
Integration notes
Built-in blanking and muting functions reduce external logic hardware. Blanking lets you ignore fixed obstructions (e.g., a machine frame) within the field; muting suspends the safety output during a defined material pass cycle. Both are configured via the controller, not dip switches. Mounting brackets and alignment aids are separate; the light curtain body is IP65 sealed. Supplied in bulk packaging — no individual retail box.
