The 20mm beam pitch and 90 beams create a detection plane covering a 1825mm protective height. Rated for 0.2m to 7.0m operating range, this curtain fits guarding zones from tight machine apertures to wider cell perimeters. The 24VDC supply is standard for safety controllers and PLC-based safety relays. IP65 ingress protection means the emitter and receiver withstand washdown spray and dust ingress — suitable for food processing, packaging lines, and wet machining areas where hose-down cleaning is routine. ## Blanking and muting for production flow Built-in blanking and muting functions let the curtain ignore fixed obstructions (like conveyor frames or part fixtures) and temporarily suspend detection during material pass-through. This avoids false trips that stop production while maintaining safety integrity for the rest of the zone. For a line running mixed product sizes, muting eliminates the need for a separate bypass circuit.","metaTitle":"Omron F3SJ-B1825N25 Safety Light Curtain, 25mm Hand Detectio","metaDescription":"Omron F3SJ-B1825N25 safety light curtain with 25mm detection capability, 1825mm protective height, 20mm beam pitch, 90 beams, IP65, 24VDC.

With 90 beams at 20mm pitch, this height covers typical access openings on machines like press brakes, assembly stations, and palletizers. The 0.2m to 7.0m operating range gives flexibility for both tight and wide guarding distances."},{"question":"What does 25mm detection capability mean in practice?","answer":"The 25mm detection capability means the curtain reliably detects objects 25mm or larger — typically fingers and hands — entering the protected zone. This qualifies as hand protection under safety standards like IEC 61496, and is the most common specification for point-of-operation guarding where operators reach into the hazard area."},{"question":"Can this light curtain be used in washdown environments?","answer":"Yes, the IP65 rating means the emitter and receiver are sealed against dust ingress and low-pressure water jets from any direction. This makes the F3SJ-B1825N25 suitable for food-and-beverage lines, meat processing, and other wet environments where hose-down cleaning is required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/F3SJ-B1825N25","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/F3SJ-B1825N25 when reusing this data.
